You can use Visual Basic to JtTite projects that display and update the data from databases. Visual Basic uses ADO.NET, which is the next generation of database technology. following Microsoft's previous version called ActiveX Data Objects (ADO). One big advantage of ADO.NET is that information is stored and transferred in Extensible Markup Language (XML). You will find more information about XML in the section "XML Data" later in this chapter.
ADO.NET allows you to access database data in many formats. The basic types of providers are OleDb. SQLClient for SQL Server (Microsoft's propri- etary DBMS). Odbc. and Oracle. Using OleDb you can obtain data from sources such as Access, Oracle, Sybase. or DB2. The examples in this text use Micro- soft's SQL Server Express (SSE). which installs automatically with Visual Studio.
