Question

1- Enforce Referential Integrity prevents you from entering a value in the ________
field if a corresponding value does not exist in the Primary key field​

Answer 1

Explanation:

A relationship in Access helps you combine data from two different tables. Each relationship consists of fields in two tables with corresponding data. For example, you might have a ProductID field in a Products table and in an OrderDetails table. Each record in the OrderDetails table has a ProductID that corresponds to a record in the Products table with the same ProductID.

When you use related tables in a query, the relationship lets Access determine which records from each table to combine in the result set. A relationship can also help prevent missing data, by keeping deleted data from getting out of synch, and this is called referential integrity.
