ADO.NET (Active Data Objects .NET) is a data access technology in the .NET framework
that enables applications to interact with databases and other data sources. It provides a set
of classes for connecting to databases, retrieving data, manipulating data, and updating
data. ADO.NET is designed for disconnected data access, meaning that data can be
retrieved, modified, and worked with without maintaining an ongoing connection to the
database.
Real-Time Example:
In a C# application, ADO.NET is used to retrieve a list of products from a database and
display it in a UI like a GridView. The data is fetched from the database, stored in a DataSet
or DataTable, and then bound to the UI controls.

The SqlDataReader is used to retrieve data from the database in a forward-only and
read-only manner. It is more efficient than a DataSet when you need to retrieve a large

A stored procedure is a precompiled set of SQL statements that are stored and executed
on the database server. They can improve performance and security by encapsulating
complex operations.
In ADO.NET, stored procedures are executed using the SqlCommand object, where the
