Implicit Checking

Definition

The UML suite supports specific diagram notation, which prescribes certain low-level details, such as the following:

• Which symbols you can use in a diagram
• Which of these symbols can be connected
• How these symbols are connected

Implicit checking enforces these rules. The UML suite monitors your actions while you create or modify a diagram. If you attempt to carry out an action that is inconsistent with the notation, a warning appears in the message area of the editor.

Other methodology constraints

On a higher level, the methodology also dictates:

• What each type of diagram represents
• When to use each type of diagram

These high-level points are taken care of by the organization of your project into phases and the types of diagrams that are available.
