ADO.NET is a data access technology in the .NET Framework that provides a set of classes for interacting with data sources, such as databases, in a disconnected manner.
The primary components are Connection, Command, DataReader, DataAdapter, and DataSet.
Connection object in ADO.NET?The Connection object is used to establish and manage a connection to a data source, such as SQL Server or Oracle.
Command object in ADO.NETThe Command object is used to execute SQL queries and commands against a data source, including SELECT, INSERT, UPDATE, and DELETE operations
DataReader is a forward-only, read-only cursor used to efficiently retrieve data from a data source in a fast and lightweight manner
Explain the difference between DataSet and DataTable in ADO.NET.
Answer: DataSet is an in-memory representation of data that can contain multiple DataTable objects, while DataTable represents a single table of in-memory data.
DataAdapter class in ADO.NET?Answer: The DataAdapter class acts as a bridge between a DataSet and a data source, facilitating the retrieval and updating of data.
Answer: Connection pooling is a technique used to manage database connections efficiently by reusing active connections instead of creating new ones for each request, improving performance
Answer: ADO.NET handles transactions using the SqlTransaction class, allowing multiple operations to be executed as a single unit of work, with methods like BeginTransaction, Commit, and Rollback.
The advantages include efficient data management, support for disconnected data architecture, strong type safety, integration with XML, and robust transaction management.
