To create diagramming exercises you must have access to a drawing tool capable of making a GIF.
For example, you might choose a tool such as Visio, or a freeware product. Later in this module, the details of exercise submission are outlined.

If you use an OO modeling computer-assisted software engineering (CASE) tool, you will still have to be able to save your diagram as a GIF to submit it to the tutors.
Open Source Case Tools can be acquired by searching the Internet.
However, use of a CASE tool is not required for this course. The course will not provide support for the use of any of the drawing tools or CASE tools, and instructions will not be provided on how to use any of these tools.

Optional books for the course include:
(as indicated below)

1. UML Distilled: Applying the Standard Object Modeling Language
2. UML Toolkit
3. Instant UML

If you'd like to purchase any of these optional texts, you can do so online at the RationalDB Store.

you will find a number of helpful references on the Help pages, including a list of frequently asked questions, links to UML Internet and print resources, and links to CASE tool vendor Web sites.
