ASP.NET Data source controls

Question

I am learning ASP.NET. I noticed there are several types of ASP.NET data source controls available in Microsoft Visual studio, including SqlDataSource, AccessDataSource, ObjectDataSource, and XmlDataSource. Does anyone could explain the differences among SqlDataSource, AccessDataSource, ObjectDataSource, and XmlDataSource? Which one is more useful in the real world? Thank you.

Answer 4

You choose XMLDataSource if you connect to an XML file. You choose AccessDataSource if your source of data is from Access database. You choose SqlDataSource if you connect to any data source that has an ADO.NET data provider (SQL Server, Oracle, OLEDB, ODBC). You choose ObjectDataSource if you want to connect to a custom object to fetch/take data from the database (a very efficient way for a medium-to-large application).

Most of my projects are using N-Tier architecture and my best option is always ObjectDataSource. It gives my team a freedom to work independently, but simultaneously in one big project!

I hope it helps you.
