Database Explorer

Description

The Database Explorer provides a quick way to examine the properties of the tables and sets in your database. The Local Tables section lists the tables (including passive-link tables) and sets in your database. When you expand the Tables section and expand a table, you will see a list of the table's fields. The entry will contain the field type and length of each field. The Sets section lists the tables in each set and their linking relationships. A single arrow indicates a one-to-one relationship. A double arrow indicates a one-to-many relationship.
