ADO.NET is the data access component for the . NET Framework. ADO.NET leverages the power of XML to provide disconnected access to data. ADO.NET is made of a set of classes that are used for connecting to a database, providing access to relational data, XML, and application data, and retrieving results.
What is ADO.NET and uses?
ADO.NET provides consistent access to data sources such as SQL Server and XML, and to data sources exposed through OLE DB and ODBC. Data-sharing consumer applications can use ADO.NET to connect to these data sources and retrieve, handle, and update the data that they contain.
What is the use of ADO.NET in C#?
ADO.NET is a set of classes that expose data access services for . NET Framework programmers. ADO.NET provides a rich set of components for creating distributed, data-sharing applications.

Where are datasets stored?
Disks or tape are most frequently used for storing data sets on a long-term basis. Disk drives are known as direct access storage devices (DASDs) because, although some data sets on them might be stored sequentially, these devices can handle direct access.
How use SQL DataReader?
If the DataReader returns multiple result sets, call the NextResult method to iterate through the result sets sequentially. The following example shows the SqlDataReader processing the results of two SELECT statements using the ExecuteReader method.

Is ADO.NET backend?
ADO.NET is a tool that acts as a bridge between the front end application and the back end database. It provides consistent access to backend technologies such as SQL Server and XML. ADO.NET includes different classes and different options to fetch data with different use-cases.
Why is ADO.NET faster?
Because ADO.NET always establishes the connection directly to the database. That's why it provides much better performance compared to the Entity Framework. It is because, in Entity Framework, the entity first translates the LINQ queries to SQL and then it processes the query to perform database operations.
Is ADO.NET fast?
ADO.NET provides better performance as it is directly connected to the data source, which makes the processing faster than Entity Framework. ADO.NET is not an open source and neither ORM.

How does .NET access data?
It takes two types of data controls to retrieve and display data in ASP.NET: A data source control - It manages the connection to the data, selection of data, and other jobs such as paging and caching of data etc. A data view control - It binds and displays the data and allows data manipulation.
