Visual Basic Concepts

Using Data Access Objects with Remote Databases

Data Access Objects (DAO) can be used either with the Microsoft Jet database engine or, using the ODBCDirect option, without it. This chapter discusses design and implementation issues that arise when using the Data Access Objects (DAO) to access remote databases.

You may find the Jet Database Engine Programmer's Guide and Hitchhiker's Guide to Visual Basic and SQL Server (both published by Microsoft Press) useful sources of information on using DAO to access ODBC data sources using Jet.

Topics
