The Referential Integrity (RI) builder helps you ensure referential integrity by setting up triggers to control how records are inserted, updated, or deleted in related tables.

The RI Builder is displayed when you:

  • Double-click a relationship line between two tables in the Database designer and choose the Referential Integrity button in the Edit Relationship dialog box.
  • Choose Edit Referential Integrity from the Database Designer shortcut menu.
  • Choose Edit Referential Integrity from the Database menu.

  • Rules for Inserting
