Enter Relations

Use the Edit Database Relations panel to enter relation statements to declare the entities in your data model. The panel shown in the following illustration has three main columns labeled Object, Relation, and Referenced object:

There are eight possible relations; however, the most common relations are:

• Has
• Known by
• Owned by
• Refers to

For ease of use and efficiency, there are some shortcuts for entering relations:

• You can use the DUP key to reduce the amount of typing. When the cursor is in a field and you press the DUP key, values from the previous line will be duplicated on the line below when you press Enter.
• You only need to type the first letter of a relation; for example, you can enter K or O in place of Known by or Owned by, respectively.

When you press Enter after entering all the relations you will get a display like the following illustration:
