In any programming language Database Programming is very essential part of it. In here you can implement your database with a single computer or within a client server system. When you are working with a stand alone pc, it is very easy to maintain the program. But when work with client server environment, database programming is little bit difficult to handle comparing with previous one.
When you are working with client server environment you must have good database management like SQL Server, My SQL, or Oracle. This DBMS manage the database that is stored in the server. When comparing with the client server with stand alone systems, client server systems need additional preparations for the tasks. Although the application software is running on the client, it uses data that stored on the server. To make this conversion with the client and the data source is possible for VB application.
The client access the database, where the data access API such as ADO.Net. Once the software for both client and server are installed, the client communicates with the server by passing SQL quarries to the DBMS through the data access API. These quarries are written in standard language like SQL. SQL lets any application to communicate with any DBMS. After implementing the SQL in the server side, the result again passed into the client for required activities.
