What is ADO.NET?

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.
