Database Connectivity in .NET Framework

This article explains how to create a connection string or database connectivity in .NET framework (for example, between MS SQL Server and Visual Studio).

Database Connectivity

So basically, what is database connectivity?

In the most simple and easy words I can say that database connectivity is nothing but an interface, bridge or a communication medium between your database and your web through which you can manage various applications or functionalities of your web.

Functionalities | Connectivity

The major functionalities of database connectivity are:

  • Helps in Session mechanism
  • Helps in solving puzzles of user registration pages
  • In database binding
  • Accessing files/data/information that is already stored in database
  • Basic operation of SQL

Coding | Web Configuration

For creating database connectivity (I am giving you guidelines on the basis of the tools in Visual Studio):

  • Open Visual Studio
  • Access your desired website
  • Access the main page of your website; the main page will be like this:

  • Now click on Solution Explorer at the very right corner; a box like this will be opened:

  • Now click on web.config link
  • A web.config page will be opened
  • Create a connection string in this page

The following shows how to establish a connection string.
