Summary

This chapter took a look at ActiveX Data Objects. ADO provides a common interface that can be used in a wide variety of different programming environments, including Visual C++, Visual Basic, VBScript, and JavaScript. ADO also enables you to access a wide variety of different OLE DB data sources. To recap:

• If you're developing new database applications, try using straight OLE DB instead of ADO. In Visual C++ 6.0, it's faster and easier.
• Various objects make up the ADO interface, including connections and recordsets, as well as several other classes that are used by these objects.
• You can perform basic database operations with ADO including connecting to a data source, forming a recordset, and executing commands.
