6.1 .NET technology and ADO.NET
.NET is Microsoft's Web services architecture, which represents a set of
Microsoft frameworks and technologies. It is alternative to J2EE, the distributed
application infrastructure based on Java language and is available for Windows
platforms.
ActiveX Data Object for .NET (ADO.NET) provides classes, methods, and
attributes to access data source utilizing features of Web services and XML.
ADO.NET serves as a single data access layer used by all server processes and
applications running on Microsoft platforms. ADO.NET consists of objects such
as Connection, Command, DataAdapter, and DataReader to access data source
