Working with Tables

  • Article

Building your database includes creating tables. When you designed your database, you specified the table fields and relationships required for your application. Now, as you create those tables, you make more detailed choices about the data types, captions, and potential default values for each field, the triggers for each table, and the table indexes you build to establish relationships between tables.
