UML:

Design a simple UML class diagram for a software address book. The address book stores contacts with names, addresses and phone numbers. Contacts may be for personal or business. Contacts are stored alphabetically on pages. For example if you turn to the C page, it will display all the contacts with last name starting with the letter C.

Notes on UML Modeling
Class Diagrams
- Are class name spellings consistent with the class naming
rules in the implementation language?
- Are class names nouns not verbs?
• Example, LoglnRecord not Login
- Do the arrows/lines properly differentiate between
inheritance and association.?
- Is cardinality correctly shown?
- Is visibility specified on all attributes and operations.
- Are the classes arranged in a visually meaningful way?
Multiple pages are to be preferred to a cluttered
arrangement that obscures the concepts. Use "off page"
connectors if necessary.

Sequence Diagrams
- Are responses shown for all "synchronous calls"?
- Do calls exit from the right-hand side of the
- Are "activation boxes" consistent with the class
-
execution definition?
- Are all message arrows shown exiting the right and
side of the "activation box"
- Are the sequences arranged in a visual meaningful
way? Again multiple pages are to be preferred to a
cluttered arrangement that obscures the concepts.
