Suggested December 2023 Cardence To Enhance Its Platform With Multiple Chainlink Oracle Services

Cardence is happy to announce that it is integrating Chainlink Price Feeds and Chainlink Verifiable Random Function (VRF) to bring enhanced functionality to its decentralized presale platform and launchpad.

Through the highly secure and reliable market data of Chainlink Price Feeds, Cardence will enable its users to participate in presales using multiple different cryptocurrencies, while the auditable source of on-chain randomness is provided by Chainlink VRF helps ensure fair and transparent reward distribution and IDO whitelisting.

Chainlink Price Feed Integration

Integrating Chainlink Price Feeds will be an important step forward for our ecosystem. Chainlink Price Feeds are the most widely used price oracle solution in the smart contract industry, already helping secure tens of billions of dollars for DeFi projects on various blockchains. For our initial integration, we are using three Chainlink Price Feeds—ETH/USD, BNB/BUSD, and MATIC/USD.

One of the constraints of traditional presale platforms is that they typically allow purchases using only a single asset. For example, on Binance Smart Chain (BSC), one can only use BNB. Similarly, ETH is Ethereum’s native payment token while Polygon’s is MATIC. Cardence is changing this dynamic by using Chainlink Price Feeds for secure and precise crypto-to-crypto conversions at the time of allocation purchases, allowing us to accept BUSD, USDT, and USD on their respective networks.

The next step will be to use more price feeds from Chainlink in order to facilitate cross-chain purchases, such as user purchases in a BSC presale using ETH. 

Unique Benefits of Chainlink Price Feeds for Cardence

Accurate Trading Data

Chainlink Price Feeds source data from numerous premium data aggregators, leading to price data that are aggregated from hundreds of exchanges (both centralized and decentralized), weighted by volume, and cleaned of outliers and suspicious volumes.

Data security

Chainlink Price Feeds decentralized the data sourcing and data delivery processes, generating strong protections against tampering or anomalies by a single or small set of exchanges, such as flash crash outliers and flash loan attacks.

High reliability

No single entity can tamper with a Chainlink Price Feed, meaning Cardence’s users get a much more objective analysis of price data because the information is supplied and evaluated by large groups of independent entities. To be specific, Chainlink Price Feeds are secured by security-reviewed, Sybil-resistant nodes run by leading blockchain DevOps teams and traditional enterprises with a strong track record for reliability.

Chainlink VRF Integration

In addition to price feeds, we are also integrating Chainlink VRF—a tamper-proof and auditable source of randomness—to distribute project prizes and airdrops, host secure and honest competitions, and engage in fair and unbiased whitelisting. We plan to create an ecosystem where projects can carry out their community-building efforts as well as their presales.

Using Chainlink VRF, we are creating a secure and transparent ecosystem that is completely impartial. This will allow us to create user reward portals for distribution of airdrops, create portals for presale whitelisting activities, and any other function where a verifiable source of randomness is required for fair and transparent selection.

Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The Cardence smart contract will only accept the random number input if it has valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof.

About Chainlink

Chainlink is the industry standard oracle network for powering hybrid smart contracts. Chainlink Decentralized Oracle Networks provide developers with the largest collection of high-quality data sources and secure off-chain computations to expand the capabilities of smart contracts on any blockchain.

Managed by a global, decentralized community, Chainlink currently secures billions of dollars in value for smart contracts across decentralized finance (DeFi), insurance, gaming, and other major industries.

About Cardence

Tips To Enhance Mobile Search Interaction

Mobile search is becoming increasingly important for companies of all shapes and sizes. According to the latest quarterly report from RKG, more than a quarter of organic and paid search traffic went through smartphones and tablets in the second quarter of this year. And this isn’t just restricted to domestic markets. In China and India, mobile has already overtaken static search, meaning that any marketers wishing to target those nations would do well to keep mobile in mind.

Mobile Mistakes

Google recently announced changes in its algorithms that would effectively penalize sites that were not optimized for mobile. Some common mistakes they listed include unplayable videos, faulty redirects, URLs that show as an error page to smartphone users, irrelevant cross-linking, and slow page loading speeds. Wherever your markets are, it’s clearly important to make your content visible and accessible to mobile users.

Make it Easier to Search

One way to ensure users can find the information they need without leaving your site is by having a high quality site search. Mobile users do not want to browse through huge product displays or be forced to navigate through several pages until they find what they want. Site search allows them to access the relevant products or pages quickly. Site search users also tend to convert at a higher rate, so it’s essential for companies to strengthen their mobile website search and maximize the website’s performance.

Here are a few tips for a more effective site search:

Use a Prominent Search Box

Don’t make them look for it!  If they want to use site search (and you want them to as well!), then it makes sense to ensure that the search box is one of the first things they see. Display it prominently at the top of the homepage and other important pages and make sure it’s clearly labelled.

Use Auto Complete

Auto Complete suggests terms when visitors type the first letters of a keyword, making it easier for users to find what they are looking for. You might also consider an Auto Suggest feature, which suggests alternative items based on products the user already viewed. The Deb Shops chain reported a 20 per cent increase in adds to cart for users exploring with a ‘More Like This…’ feature.

Use Infinite Scrolling

Provide Localized Information                

Many mobile search tasks are localized in nature, meaning users are looking for goods or services relevant to their current location. This can be provided using the mobile device’s GPS tracking facilities.

Display your Promotions

When visitors search for a brand name or product that is on sale, include a keyword-driven banner at the top of the search results to emphasize that promotion. You get to push your promotion and the visitor could get a great deal!

As mobile usage continues to grow, businesses will need to focus on making their mobile sites easy to navigate. What suggestions do you have for making mobile sites more user friendly?

How To Add Multiple Users With Bulk Import In Office 365

This feature allows you to import multiple users’ information into Office 365 from a single file source. The file must be a comma-separated values (CSV) file and adhere to the required format. It will then automatically do the rest of the thing for you.

So, before I start telling you the steps to use the bulk import, you must first know about CSV files and how to create an Office 365 supported file.

A CSV file is an easy way to transfer a large amount of data between programs. It is a plain-text file that stores database-style information in a particular format. The format requires one record on each line. Commas must separate fields within records.

You can use the Bulk add users wizard to upload an existing CSV file, or you can use the provided blank CSV template and edit it in a text editor such as Notepad.

The template contains user data column labels under which you enter information about the users you want to import. The wizard also includes a sample CSV file that provides a correctly formatted example containing sample user data.

When you create a CSV file, you can enter user data column labels in any language or characters, but the order of the labels, as shown in the sample, is essential for the correct fields to be populated. You can then make entries into the fields, using any language or characters, and save your file in a Unicode or UTF-8 format.

The minimum number of rows is two, including the first row of user data column labels (the second row is a user). The maximum number of rows is 251, including the first row of user data column labels. Only the user name and display name are required entries. If you need to import more than 250 users, create multiple CSV files.

The user data column labels and maximum character length for each in the sample CSV file are:

User Name (Required): The maximum total length of the user name is 79 characters (including @ symbol) in the format [email protected] The user’s alias cannot exceed 30 characters, and the domain name cannot exceed 48 characters.

First Name: 64

Last Name: 64

Display Name (Required): 256

Job Title: 64

Department: 64

Office Number: 128

Office Phone: 64

Mobile Phone: 64

Fax: 64

Address: 1024

City: 128

State or Province: 128

ZIP or Postal Code: 40

Country or Region: 128

While making your CSV file for Office 365, you must keep these few things in mind, or else you will get an error:

Suppose you are importing users from different countries or regions. In that case, we recommend creating a separate CSV file for each country or region and performing a bulk import operation for each CSV file. You will indicate the users’ location in the CSV file as part of this import process, and only one location can be selected per bulk import operation.

Ensure that the User Name column of your CSV file contains the full email address (for example, [email protected]) for each of your users, or you will receive an error when you upload the file.

Add users with bulk import in Office 365

Once your CSV file is ready, you are now ready to add multiple users. Take the following steps to perform the action.

Do not add, change, or delete column labels in the CSV template or sample file, and make sure that you save the file with a .csv extension, or the file may not upload correctly.

Can multiple users use the same Office 365 account?

Microsoft Office 365 works on multiple PCs, and it can use on up to 5 devices simultaneously as well. However, it has to be the same account and either directly subscribed or part of the Microsoft 365 Family subscription. If you try to sign to more than five devices, Office will sign out of one other device, so the limit is honored. However, for Office for Business, you can install and sign in to Office on 5 PCs or Macs, five tablets, and five phones.

Is Office 365 per user or per device?

Microsoft 365 subscriptions provide per-user licenses, so you must use the same account everywhere. Using Office 365 for home lets, you add more users based on family sharing.

Restful Web Services Tutorial: What Is Rest Api With Example

What is Restful Web Services?

Restful Web Services is a lightweight, maintainable, and scalable service that is built on the REST architecture. Restful Web Service, expose API from your application in a secure, uniform, stateless manner to the calling client. The calling client can perform predefined operations using the Restful service. The underlying protocol for REST is HTTP. REST stands for REpresentational State Transfer.

In this REST API tutorial, you will learn-

RESTful Key Elements

REST Web services have really come a long way since its inception. In 2002, the Web consortium had released the definition of WSDL and SOAP web services. This formed the standard of how web services are implemented.

In 2004, the web consortium also released the definition of an additional standard called RESTful. Over the past couple of years, this standard has become quite popular. And is being used by many of the popular websites around the world which include Facebook and Twitter.

The key elements of a RESTful implementation are as follows:

Request Headers – These are additional instructions sent with the request. These might define the type of response required or the authorization details.

Request Body – Data is sent with the request. Data is normally sent in the request when a POST request is made to the REST web services. In a POST call, the client actually tells the REST web services that it wants to add a resource to the server. Hence, the request body would have the details of the resource which is required to be added to the server.

Response Status codes – These codes are the general codes which are returned along with the response from the web server. An example is the code 200 which is normally returned if there is no error when returning a response to the client.

Restful Methods

The key elements of a RESTful implementation are as follows:

The below diagram shows mostly all the verbs (POST, GET, PUT, and DELETE) and an REST API example of what they would mean.

POST – This would be used to create a new employee using the RESTful web service

GET – This would be used to get a list of all employee using the RESTful web service

PUT – This would be used to update all employee using the RESTful web service

DELETE – This would be used to delete all employee using the RESTful services

The following actions would have their respective meanings.

POST – This would not be applicable since we are fetching data of employee 1 which is already created.

GET – This would be used to get the details of the employee with Employee no as 1 using the RESTful web service

PUT – This would be used to update the details of the employee with Employee no as 1 using the RESTful web service

DELETE – This is used to delete the details of the employee with Employee no as 1

Why Restful

Restful mostly came into popularity due to the following reasons:

1. Heterogeneous languages and environments – This is one of the fundamental reasons which is the same as we have seen for SOAP as well.

It enables web applications that are built on various programming languages to communicate with each other

With the help of Restful services, these web applications can reside on different environments, some could be on Windows, and others could be on Linux.

But in the end, no matter what the environment is, the end result should always be the same that they should be able to talk to each other. Restful web services offer this flexibility to applications built on various programming languages and platforms to talk to each other.

The below picture gives an example of a web application which has a requirement to talk to other applications such Facebook, Twitter, and Google.

Now if a client application had to work with sites such as Facebook, Twitter, etc. they would probably have to know what is the language Facebook, Google and Twitter are built on, and also on what platform they are built on.

Based on this, we can write the interfacing code for our web application, but this could prove to be a nightmare.

Facebook, Twitter, and Google expose their functionality in the form of Restful web services. This allows any client application to call these web services via REST.

2. The event of Devices – Nowadays, everything needs to work on Mobile devices, whether it be the mobile device, the notebooks, or even car systems.

Can you imagine the amount of effort to try and code applications on these devices to talk with normal web applications? Again Restful API’s can make this job simpler because as mentioned in point no 1, you really don’t need to know what is the underlying layer for the device.

3. Finally is the event of the Cloud – Everything is moving to the cloud. Applications are slowly moving to cloud-based systems such as in Azure or Amazon. Azure and Amazon provide a lot of API’s based on the Restful architecture. Hence, applications now need to be developed in such a way that they are made compatible with the Cloud. So since all Cloud-based architectures work on the REST principle, it makes more sense for web services to be programmed on the REST services based architecture to make the best use of Cloud-based services.

Restful Architecture

An application or architecture considered RESTful or REST-style has the following characteristics

1. State and functionality are divided into distributed resources – This means that every resource should be accessible via the normal HTTP commands of GET, POST, PUT, or DELETE. So if someone wanted to get a file from a server, they should be able to issue the GET request and get the file. If they want to put a file on the server, they should be able to either issue the POST or PUT request. And finally, if they wanted to delete a file from the server, they can issue the DELETE request.

2. The architecture is client/server, stateless, layered, and supports caching

Client-server is the typical architecture where the server can be the web server hosting the application, and the client can be as simple as the web browser.

Stateless means that the state of the application is not maintained in REST. For example, if you delete a resource from a server using the DELETE command, you cannot expect that delete information to be passed to the next request.

RESTFul Principles and Constraints

The REST architecture is based on a few characteristics which are elaborated below. Any RESTful web service has to comply with the below characteristics in order for it to be called RESTful. These characteristics are also known as design principles which need to be followed when working with RESTful based services.

RESTFul Client-Server

This is the most fundamental requirement of a REST based architecture. It means that the server will have a RESTful web service which would provide the required functionality to the client. The client send’s a request to the web service on the server. The server would either reject the request or comply and provide an adequate response to the client.


The concept of stateless means that it’s up to the client to ensure that all the required information is provided to the server. This is required so that server can process the response appropriately. The server should not maintain any sort of information between requests from the client. It’s a very simple independent question-answer sequence. The client asks a question, the server answers it appropriately. The client will ask another question. The server will not remember the previous question-answer scenario and will need to answer the new question independently.


The Cache concept is to help with the problem of stateless which was described in the last point. Since each server client request is independent in nature, sometimes the client might ask the server for the same request again. This is even though it had already asked for it in the past. This request will go to the server, and the server will give a response. This increases the traffic across the network. The cache is a concept implemented on the client to store requests which have already been sent to the server. So if the same request is given by the client, instead of going to the server, it would go to the cache and get the required information. This saves the amount of to and fro network traffic from the client to the server.

Layered System

The concept of a layered system is that any additional layer such as a middleware layer can be inserted between the client and the actual server hosting the RESTFul web service (The middleware layer is where all the business logic is created. This can be an extra service created with which the client could interact with before it makes a call to the web service.). But the introduction of this layer needs to be transparent so that it does not disturb the interaction between the client and the server.

Interface/Uniform Contract

This is the underlying technique of how RESTful web services should work. RESTful basically works on the HTTP web layer and uses the below key verbs to work with resources on the server

POST – To create a resource on the server

GET – To retrieve a resource from the server

PUT – To change the state of a resource or to update it

DELETE – To remove or delete a resource from the server

Create your first Restful web service in ASP.NET

Now in this REST API tutorial, we will learn how to create a Restful web service in ASP.NET:

Web services can be created in a variety of languages. Many integrated development environments can be used to create REST-based services.

In this RESTful API example, we are going to create our REST application in .Net using Visual Studio. In our example, for Restful web services we are going to emulate the following REST service example.

We are going to have a Restful web service which will work on the below set of data.

The below set of data represents an REST API example of having a company which exposes the Tutorial’s they have based on the Tutorialid.

Tutorialid TutorialName

0 Arrays

1 Queues

2 Stacks

In our REST API tutorial example, we are going to implement the below Restful Verbs.

GET Tutorial – When a client invokes this Restful API, they will be given the entire set of Tutorials available from the web service.

GET Tutorial/Tutorialid – When a client invokes this Restful API, they will be given the Tutorial name based on the Tutorialid sent by the client.

POST Tutorial/Tutorialname – When a client invokes this Restful API, the client will submit a request to insert a Tutorialname. The web service will then add the submitted Tutorial name to the collection.

DELETE Tutorial/Tutorialid– When a client invokes this Restful API, the client will submit a request to delete a Tutorialname based on the Tutorialid. The web service will then delete the submitted Tutorial name from the collection.

Let’s follow the below steps in this RESTful API tutorial to create our first RESTful web services, which carries out the above implementation.

How to Create Your First Resful Web Service

Step 2) Enter project name and location.

Ensure to first choose the RESTful web services C# web template of chúng tôi Web application. The project has to be of this type in order to create web services project. By choosing this options, Visual Studio will then carry out the necessary steps to add required files which are required by any web-based application.

Give a name for your project which in our case has been given as “Webservice.REST”.

Then ensure to give a location, where the project files will be stored.

Once done you will see the project file created in your solution explorer in Visual Studio 2013.

The next step is to create the web service file which is going to have the RESTful web service

In this step,

In the dialog box which appears, you need to perform the following

Choose the option of WCF Service (Ajax-enabled) – Choose a file of this type, it causes the Visual studio to add some basic code which helps one create a RESTful web service. WCF stands for Windows Communication Foundation. WCF is a library for applications of various platforms or the same platform to communicate over the various protocols such as TCP, HTTP, HTTPS. Ajax basically is Asynchronous JavaScript and XML. AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes.

Next give a name for the service which is TutorialService in our case.

The next step is to actually make a configuration change to enable this project to complete work with RESTful web services. This requires to make a change to the file called Web.config. This file appears in the same window as the Webservice project file. The file Web.config contains all configurations that make the web application work as it should. The change being made actually allows the application to send and receive data as a pure RESTful web service.

The next step in this RESTful API tutorial is to add our code for implementation. All of the below-mentioned code has to be written in the chúng tôi file

The first bit is to add code to represent our data which will be used in our program. So we are going to have a list of string variables with values of “Arrays”, “Queues” and “Stacks”. This will represent the tutorials name available through our hosting web service.

namespace Webservice.REST { [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed public class TutorialService { (new String[] {"Arrays","Queues","Stacks"});

Next we will define the code for our GET method. This code will also reside in the same chúng tôi file. This code will run whenever we call the service from our browser.

The below method will be used to fulfill the below-mentioned scenario

If a user wants a list of all Tutorials available, then the below code would need to be written to accomplish this.

[WebGet(UriTemplate="/Tutorial")] public String GetAllTutorial() { int count = 1st.Count; String TutorialList = ""; for (int i = 0; i < count; i++) TutorialList = TutorialList + lst[i] + ","; return TutorialList; }

Code Explanation:-

This section of code is used to go through our list of strings in the ‘lst’ variable and return all of them to the calling program.

The code below ensures that if a GET call is made to the Tutorial Service with a Tutorial id, then it would return the corresponding Tutorial Name based on the Tutorial id.

[WebGet (UriTemplate = "/Tutorial/{Tutorialid}")] public String GetTutorialbyID(String Tutorialid) { int pid; Int32.TryParse(Tutorialid, out pid); return lst[pid]; }

Code Explanation:-

This section of code is used to return the “Tutorial name” which has the Tutorial id passed to the web method.

By default, what needs to be remembered is that whatever is passed to the URL in the browser is a string.

But you have to remember that the Index to our list has to be an integer, so we are adding the necessary code to first convert the Tutorialid to an Integer and then use it to access the index position in our list and

Then return the value to the calling program accordingly.

The next step is to write up the code for our POST method. This method will be invoked whenever we want to add a string value to our list of Tutorials via the POST method. For example, if you wanted to add the Tutorial name of “Software Testing” then you would need to use the POST method.

Code Explanation:-

The first line is the ‘WebInvoke’ attribute which has been attached to our method. This allows the method to be invoked via the POST call. The RequestFormat and ResponseFormat attribute have to be mentioned as JSON, since when posting values to a RESTFul web service, the values have to be in this format.

The second line of code is used to add the string value passed via the POST call to our existing list of Tutorial strings.

Finally we are going to add our method to handle the DELETE operation. This method will be invoked whenever we want to delete an existing string value from our list of Tutorials via the DELETE method.

[WebInvoke(Method = "DELETE", RequestFormat = WebMessageFormat.Json, UriTemplate = "/Tutorial/{Tutorialid}", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)] public void DeleteTutorial(String Tutorialid) { int pid; Int32.TryParse(Tutorialid, out pid); 1st.RemoveAt(pid); }

Code Explanation:-

The first line is the ‘WebInvoke’ attribute which has been attached to our method. This allows the method to be invoked via the POST call. The RequestFormat and ResponseFormat attribute have to be mentioned as JSON, since when posting values to a RESTFul web service, the values have to be in this format. Note that the Method parameter is being set to “DELETE.” This means that whenever we issue the DELETE verb, this method will be invoked.

The second line of code is used to take the Tutorialid sent via the DELETE call and subsequently delete that id from our list. (The Int32 function in code is used to convert the Tutorial ID from a string variable to an integer).

Running your first Restful web service

Now that we have created our entire web service in the above section. Let’s see how we can run the Tutorial service so that it can be invoked from any client.

To run the web service, please follow the below steps

Step 2) Choose the menu option ‘Set as StartUp Project’. This will ensure that this project is run when Visual Studio runs the entire solution


When the project is run, you can browse to your chúng tôi section, and you will get the below output.

In the above output,

You can see that the browser is invoking the ‘GET’ verb and executing the ‘GetAllTutorial’ method in the web service. This module is used to display all the Tutorials exposed by our web service.

Testing your first Restful web service

In the above section, we have already seen how to use the browser to execute the ‘GET’ verb and invoke the ‘GetAllTutorial.’

Let’s now use the browser to execute the following use case scenario.

GET Tutorial/Tutorialid – When a client invokes this Restful API, they will be given the Tutorial name based on the Tutorialid sent by the client

In your browser, append the string /1 after the Tutorial word in the URL. If you hit the enter button, you will get the below output

Now you will see the output of Queues which actually corresponds to the number 1 in our list of Tutorial Strings. This means that the ‘GetTutorialbyID’ method is now being invoked from our Webservice. It also shows that the value of 1 is being passed successfully via the browser to our web service and to our method and that is why we are getting the correct corresponding value of “Queues” in the browser.

Next let’s consume our web service by executing the below scenario. For this, you need to install the tool called “Fiddler” which is a free downloadable tool from the site.

POST Tutorial/Tutorialname – When a client invokes this Restful API, the client will submit a request to insert a Tutorialname. The web service will then add the submitted Tutorial name to the collection.

Run the Filddler tool and perform the below steps;

Go to the composer section. This is used to create requests which can be submitted to any webapplication.

Make sure the Content-Type is marked as application/json. Remember that our POST request method in our Web service only accepts json style data so we need to ensure this is specified when we are sending a request to our application.

Finally, we need to enter our data. Remember that our method for POST accepts a parameter called ‘str.’ So here we are specifying that we want to add a value called “Trees” to our collection of Tutorial names and ensure that it is tagged to the str variable name.

Now, when we browse to the Tutorial URL to show all the strings in our Tutorial list, you will now see the value of “Trees” is also present. This shows that the POST request to the web service was successfully executed and that it was successfully added to our Tutorial List.

Next let’s consume our web service by executing the below scenario. For this also we need to use the fiddler tool

DELETE Tutorial/Tutorialid- When a client invokes this Restful API, the client will submit a request to delete a Tutorialname based on the Tutorialid. The web service will then delete the submitted Tutorial name from the collection.

Run the Filddler tool and perform the below steps

Go to the composer section. This is used to create requests which can be submitted to any webapplication.

Now, when we browse to the Tutorial URL to show all the strings in our Tutorial list, you will notice that the value of “Queues” is no longer present.

This shows that the DELETE request to the web service was successfully executed. The element at index no 1 in our list of Tutorial strings was successfully deleted.


REST stands for REpresentational State Transfer. REST is used to build web services that are lightweight, maintainable, and scalable in nature.

More and more applications are moving to the Restful architecture. This is because there are a lot of people now using mobile devices and a wider variety of applications moving to the cloud.

The main aspects of REST are the resources which reside on the server and the verbs of GET, POST, PUT and DELETE, which can be used to work with these resources.

Visual Studio chúng tôi can be used to create Restful web services.

When Testing web services for POST and PUT, you need to use another tool called fiddler which can be used to send the POST and PUT request to the server.

Oracle Vs Sql Server – Difference Between Them

Key Differences between Oracle and SQL Server

Oracle runs on a wide variety of platforms, while the SQL server can be installed on a handful of platforms.

Oracle supports star query optimization while SQL server doesn’t offer query optimization.

In oracle, values do not change before committing, whereas in SQL Server values are changed even before committing.

Oracle allows rollback during the transaction process, whereas SQL server doesn’t allow rollback in the transaction process.

Oracle supports many “Schemas” with the instance, whereas SQL server offers “Schemas” within each user database.

Oracle allows database, full, file-level, incremental & differential backups, on the other hand, SQL server allows full, partial, and incremental backups.

Oracle uses both “after” and “before” triggers, whereas SQL server mostly uses only “after” triggers.

Oracle vs SQL Server

What is Oracle Database?

Oracle database is an RDMS system from Oracle Corporation. The software is built around the relational database framework. It allows data objects to be accessed by users using SQL language. Oracle is a completely scalable RDBMS architecture which is widely used all over the world.

Oracle is one of the biggest vendor in the IT market and the shorthand name of its flagship RDBMS product, that was formally called Oracle Database.

What is Microsoft SQL server?

MS SQL server is a database product of Microsoft. It allows users to SQL queries and execute them. It is among the most stable, secure and reliable database solutions. It supports wide variety of transaction processing, analytics, and business intelligence applications in corporate IT environments.

Difference between SQL Server and Oracle

Early History of Microsoft SQL:

In 1987, Microsoft partnered with Sybase Solutions for developing DBMS which may compete with other IT giants like IBM and Oracle. Both these companies agreed that Sybase will have all the selling rights and profit earned from the product designed for the Non-Microsoft platform.

Microsoft, on the other hand, will have rights to the database product designed for Microsoft Platforms. In 1989 the first database server product version was released.

After that, Microsoft purchase all the rights from Sybase and they changed the name to MS SQL Server. Till date, 30 versions of MS SQL, has been released.

Early History of Oracle:

Oracle Corporation has a distance long journey to become the multinational technology company that it has at the current time.

In 1977 the Oracle Organisation was founded by two developers, Larry Ellison and Bob Miner. Both had prior experience in developing database software for different organizations.

In the year 1978, they were able to build a first RDBMS using SQL. This software is known as Oracle Relational Database Management System.

Oracle became the first company to sell the RDBMS software and within 1982 had yearly revenue of $2.5 million.

Oracle Lifts Peoplesoft Bid By $1.2 Billion

billion to $6.3 billion, significantly sweetening the offer in what has become an escalating takeover/merger struggle among three enterprise application companies.

The database giant also fired back at lawsuits from PeopleSoft and its intended merger partner before Oracle’s bid, J.D. Edwards , by saying it intends to file a suit against the companies.

was a fair offer.

Oracle Executive Vice President Chuck Phillips moved to clear up any misconceptions on a conference call Wednesday.

“We are extending the support period for PeopleSoft products,” said Phillips. “Contrary to numerous reports in the press, we do not plan to eliminate support for PeopleSoft products — period. PeopleSoft customers will not be forced to migrate to Oracle applications — period. Instead, when and if these customers elect to migrate to Oracle’s eBusiness Suite, they will receive a free license upgrade for like modules.”

Oracle’s reaffirmation of its intent was supported in the industry.

Ken Marlin, managing partner at high-tech investment consulting firm Marlin & Associates, said the bid increase solidifies Oracle’s intent as serious.

“Absolutely, I think it’s attractive,” Marlin told chúng tôi “They’ve [Oracle] been serious from the begining. Pundits have speculated somehow that he [Ellison] was not, but this has always made fabulous strategic sense for Oracle. I think that Ellison’s opening bid was a reasonable place to start. He signaled from the beginning that he tried to have discussions with PeopleSoft and negotiate in good faith to remove the poison pill. This new bid values the company at 3 times its current revenue. That’s a healthy price for a company whose revenue growth is not what it once was.”

Marlin said all industry eyes are now on PeopleSoft. “This puts pressure on PeopleSoft’s board to exercise fiduciary reponsibility to the shareholders. This is a classic case of where we’ll find out whose interests the board is trying to protect. I think the probability is very high that if PeopleSoft spurns Oracle, and goes ahead with its J.D. Edwards merger, you’ll see a drop in their purchase price. There is some danger that PeopleSoft’s stock price will drop below Oracle’s original bid of $16 — and then you’ll see some lawsuits.”

Forrester Research analyst Paul Hamerman agreed the bid increase shows that Oracle is serious. However, he still believes that if PeopleSoft’s board takes the offer to shareholders and they approve the offer, the deal could be tied up by regulatory issues for months.

“Oracle still gains if this runs into regulatory issues,” Hamerman told chúng tôi “Even if they’re not successful, they will have disrupted PeopleSoft’s sales cycle and left a dark cloud over that company. This just gets uglier by the minute and there will be more lawsuits.”

Also, in its response to lawsuits by both PeopleSoft and J.D. Edwards over the hostile bid, Oracle also said it will file suit Wednesday in a Delaware court against PeopleSoft, its board of directors, and J.D. Edwards “in response to their collective efforts to eliminate PeopleSoft shareholders’ ability to accept Oracle’s tender offer.”
