ADO.NET is a disconnected, n-tier data-access model with better integration with XML and XSD. ADO.NET has two core components: .NET Data Provider and DataSet. The Data Provider defines a set of interfaces for data access and provides and resolves data to and from a DataSet. DataSet represents relational data in memory from a data source. The data source can be either a Relational Database Management System (RDBMS) or an XML file. This paper introduces the Borland ® Data Provider (BDP) for the Microsoft® .NET Framework included in Borland rapid application development (RAD) tools, such as the newly released Borland ® C#Buildertm - a pure C# development solution for .NET. BDP is a .NET data provider implementing the Microsoft .NET Data Provider core interfaces. BDP provides a set of Common Language Runtime (CLR) components that allows data access from one of the BDP supported databases. BDP also comes with a rich set of component designers and tools that make database development easier. BDP architecture 永遠追不上技術更新的速度
