A table relation associates two tables that contain related information. Usually the primary key field of one table appears as a foreign key field of the related table. The table with the primary key is called the parent table. The table with the foreign key is called the child table.
For example, a parent table named Department can have a departmentId field as its primary key. A child table named Employee can have a departmentId field as a foreign key. All values in the foreign key field must exist in the primary key field of the parent table. Any value in the foreign key field can be used to find the parent row that contains the matching primary key value. Then any other field in the parent row can be accessed.
For a list of the tables that are related to a specific table, see the Help topic for the specific table. The Help topic has a section named Relations. These reference topics are available at Tables.
