Table names and types
See your database software documentation to determine valid file names for its tables. For example, an Access table has no extension requirement because it is stored within an Access database with an .MDB extension. On the other hand, .DB is the required extension for Paradox tables and .DBF for dBASE tables.
The table name should indicate its purpose and be easy to remember. For example, if a table contains employee information, you might call it EMPLOYEE.DBF.
Table types
The table type determines the file format of a table.
The table type you define depends on the way you plan to use the table. If you expect to use the table only with dBASE Plus applications, the dBASE Level 7 format is recommended for its flexibility and rich feature set. If the table is to be shared with other applications, consider the most useful format for all applications involved.
The dBASE Level 7 format offers all the features of the previous dBASE file formats, including expression indexes and extensive table-, row-, and field-level security.
The dBASE Plus interface adjusts automatically to accommodate the type of table you are using. For example, if the table with which you are working supports it, you can specify data-entry constraints in the Inspector while working in the Table designer. Otherwise, data-entry constraints are unavailable in the Table designer.
