Introduction to "Relationships" In an Access database, there is a relationship between the data in different tables, which links each data record in each table in the database to the only subject in the database, making the operation of a single data the whole operation of the database, the so-called "far-reaching". Take a few lessons to set up the table, the "Customer Information table" in the "Company n

In the Access database, there is a relationship between data in different tables. This relationship Associates each data record in each table in the database with a unique topic in the database, this makes all operations on a data database an overall operation. Take the tables created in the previous lessons as an example. In the

Using Access as an application is often made into two databases: Data and program. The data database only stores data tables, and the program database stores all form, query, report, and module, you can access tables in all data databases through the table Connection Program database.

We open a database for analysis, and then click Analysis on the Tools menu, and the menu pops up with the table, performance, and document manager three commands. These three commands can be optimized for the appropriate content. 1, first of all to the table to optimize, click the "table" this command. Access begins to prepare the Table Analyzer Wizard, on the first page of the wizard, which provides us with a common problem when creating
