Introduction A Data Dictionary provides the software developers with further detail on the properties of a Class Diagram. Unlike Class Diagrams a Data Dictionary does not show relationships or methods. Class Diagrams are sometimes created, or completed, after the Data Dictionary is completed. Data Dictionaries are often used in SDLC and in developing the user interface (Screens & Reports).
