ADO.NET is a set of computer software components that can be used by programmers to access data and data services. It is a part of the base class library that is included with the Microsoft .NET Framework.
It is commonly used by programmers to access and modify data stored in relational database systems, though it can also be used to access data in non-relational sources. ADO.NET is sometimes considered an evolution of ActiveX Data Objects (ADO) technology, but was changed so extensively that it can be conceived of as an entirely new product.

ADO.NET consists of two primary parts: the Data Provider and the Datasets.
Data Providers are classes that provide access to a data source, such as a Microsoft SQL Server or Oracle database and OLEDB data provider. Each data source has its own set of provider objects, but they each have a common set of utility classes which are connection, command, parameter, DataAdapter, and DataReader. Learn more about this with the houston .net consultant.
DataSets objects, a group of classes describing a simple in-memory relational database, were the star of the show in the initial release (1.0) of the Microsoft .NET Framework. The classes form a containment hierarchy which is DataSet object, DataTable object, DataView object, DataColumn, DataRow object, DataRowView, DataRelation, and Constraint.
A DataSet is populated from a database by a DataAdapter who’s Connection and Command properties have been set. However, a DataSet can save its contents to XML, or populate itself from XML, making it exceptionally useful for web services, distributed computing, and occasionally-connected applications. Learn more about this with the houston .net consultant.
Functionality exists in the Visual Studio .NET IDE to create specialized subclasses of the DataSet classes for a particular database schema, allowing convenient access to each field through strongly-typed properties.
This helps catch more programming errors at compile-time and makes the IDE's Intelligence feature more useful. For more information about the .NET, then visit the houston .net consultant.
