ADO.NET Architecture
ADO.NET's architecture is based on two main concepts: disconnected data and the eXtensible Markup Language (XML). Having these items at the core of ADO.NET makes for a powerful and flexible data access object.
ADO.NET is based on an XML format, which provides for richer data types, sharing of data, and improved performance. All these topics will be discussed in this appendix.
The main components that make up ADO.NET include the Connection, Command, DataAdapter, and DataSet objects. We'll also look at XML Schema Definition (XSD) schemas and the role they play with datasets.
