Subdatasheets—A Product of Relationships

Did you notice the plus signs (+) to the left of each record in the Catalog table as you worked with it? Access displays those signs in the primary key table when a relationship exists between two tables. If you open all three tables, as we’ve done in Figure 6.17, you’ll see that the Types and Catalog tables both have a column of plus signs, but the Plants table doesn’t.

Figure 6.17. The plus signs in a table indicate that Access has related records available.
