1. An Introduction to Models & The UML The Unified Modeling Language Copyright © 2007 Patrick McDermott College of Alameda pmcdermott@peralta.edu Not really Unified… Not a Language… But you CAN Model!

2. Why Model? Business modeling is an important skill for the analyst: not only is it a powerful tool for conducting analysis and design, but frequently coders receive specifications as models and therefore must be able to read them. “We decide which details are irrelevant for the questions of interest and proceed to ignore them. This has the effect of collecting into a category things that differ only in the abandoned details; the category becomes a building block for the model.” —John Holland

3. The UML UML unified three competing Object Oriented (O/O) methodologies into a single methodology- independent modeling technique. UML is has gained wide acceptance within the O/O community and has become a standard tool for O/O development. It has been adopted by the largest players in the software industry (IBM, Microsoft, Oracle and Hewlett Packard, for example). The major O/O modeling techniques include: Use Cases, CRC (Class-Responsibility-Collaborators) sessions, Static Structure (Class and Object) diagrams, Interaction (Sequence and Collaboration) diagrams, and State and Activity diagrams.
