What is ADO.NET and What Should You Know About It?

What is ADO.NET and What Is It Used For?

ADO.NET is a data access technology within the .NET Framework that enables applications to communicate with various data sources, such as SQL Server, Oracle, MySQL, and other databases.

ADO.NET provides a variety of Data Providers, each designed to work with specific database systems or communication protocols. Regardless of the provider you use, the programming model remains largely the same.

The most commonly used ADO.NET objects include:

• SqlConnection – Establishes and manages the connection to a SQL Server database.
• SqlCommand – Executes SQL queries, commands, and stored procedures.
• SqlDataReader – Provides fast, forward-only, read-only access to data.
• DataSet – Allows working with disconnected data in memory.
• SqlDataAdapter – Transfers data between the database and a DataSet for reading and updating.

Throughout this course, you will work with SQL Server as the database management system while learning how to build real-world Windows applications using ADO.NET.
