SqlDataSource and ObjectDataSource Differences

why we should use SqlDataSource and why ObjectDataSource.
why we do not directly use SqlDatasource and prefer ObjectDataSource even SqlDatasource is less code and fast also.

> Basically ObjectDatasource is business object that calls the stored procedure to get records from database whereas we can do directly this one by using Sqldatasource in very less code.

> Objectdatasource provide a perfect abstraction of our design and code.

> While using objectdatasource our pages does not depend upon the database information used in code behind.

> SqlDataSource is typically two-tier in nature but ObjectDataSource is based on three-tier architecture.

> SqlDataSource requires very less line of code to connect with database and ObjectDataSource needs more coding to build data access classes to communicate with database.

> SqlDataSource does not support data encapsulation whereas ObjectDataSource is fully designed for encapsulation.

> For SqlDataSource we write complete connection string for database connection. ObjectDataSource exposes TypeName attribute as a middle layer class mainly used to perform database operations.

> Sqldatasource uses ADO.NET mainly. we have to write all database queries, connections and commands on the page which looks very raw data.

> Objectdatasource behave like a wrapper which control all crud operations.

> Normally if we have to do same thing for a short time span and for a limited time perioed then it's okay to use SqlDatasource but when we talk about a big application and for long run we prefer to use Objectdatasource because direcltly use sqldatasource in your code behind is very quick but dirty habbit which is not preferable always.

> When we face frequent changes in our system then we have to go for page by page and change all sections of code which are directly accessing that change. so by using objectdatasource it is very professional and pretty to have such changes in practice.
