Explain the difference between ADO.NET and traditional ADO.?

• ADO (ActiveX Data Objects): ADO is a COM-based technology that works with

databases in a connected environment (requiring an open connection to the

database for the duration of data retrieval).

• ADO.NET: ADO.NET, in contrast, focuses on disconnected data access. It allows

you to retrieve data, work on it offline (disconnected), and then send any changes

back to the database.

Key Differences:

• ADO relies on active connections to the database, whereas ADO.NET uses a

disconnected model (DataSet, DataTable).

• ADO.NET provides better support for XML, scalability, and performance in multi-tier

applications.
