The ADO.NET of the .NET Framework

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: its Data Provider and its DateSets.
The ADO.NET Data provider classes 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:
Connection: Provides a connection used to communicate with the data source. Also acts as an abstract factory for command objects. Learn more of this with the austin .net developer.
Command: Used to perform some action on the data source, such as reading, updating, or deleting relational data.
Parameter: Describes a single parameter to a command. A common example is a parameter to a stored procedure. Learn more of this with the austin .net developer.
DataAdapter: A bridge used to transfer data between a data source and a DataSet object. Learn more of this with the austin .net developer.
DataReader: Used to efficiently process a large list of results one record at a time. It allows records to be accessed in a read-only, forward-only mode, i.e., records have to be accessed in sequential order; they can neither be randomly accessed nor can a record which has been processed previously be accessed again. Learn more of this with the austin .net developer.
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. A DataSet is populated from a database by a DataAdapter whose 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.
