Day 4. Building a Database and Organizing Data > Creating Data Relationships

Creating Data Relationships

Different database applications have widely varying methods for creating relationships, and, in fact, some consultants have built entire careers around mastering the methods of just one application. For this 21-day tutorial, I'll detail a fairly simple relationship—the list box—and hope that the concept gets your mental gears spinning and causes you to seek out other ways to share table data.
