Frequently Answers and Questions

How do I define a primary key in a table?

To define a primary key, you need to open the table in Design view. There you can click the desired field in the Field Name column and then click the Primary Key button in the Tools group on the TABLE TOOLS DESIGN tab. A key icon is inserted in the field selector bar for the desired field.

How do I create a one-to-many relationship between tables?

In Access, you can create a one-to-many relationship between tables by dragging the common field from the primary table's field list box to the related table's field list box. This will open the Edit Relationships dialog box. Here, you can select the Enforce Referential Integrity option to ensure that the relationship between records in related tables is valid.

What is referential integrity and how do I enforce it?

Referential integrity is a set of rules that ensure consistency between related tables. It prevents you from adding a record to a related table if the primary key value does not exist in the primary table. To enforce referential integrity, you need to check the Enforce Referential Integrity box during the relationship creation process.
