Modeling tools to work with UMP

There are three categories of modeling tools:

CASE (Computer Aided Software Engineering)
Graphics tools
Visualizers

CASE (Computer Aided Software Engineering)

CASE tool allows not only drawing model diagrams, but also checking diagram rules and consistency. Some tools are capable of generating code from the model.

CASE tools' pro and contra:

Pro	Contra
Ease of modeling (diagram drawing)	High cost
Automatic model consistency	Modeling constraints
Code generation	Difficult (or impossible) to customize
Document generation

Graphics tools

Graphics tools allow drawing diagrams as vector graphics.

Graphics tools' pro and contra:

Pro	Contra
Ease of modeling (diagram drawing)	Model inconsistency and errors
Customized models	Difficulty in supporting changes
Low to average cost

See UMP modeling templates for Microsoft Visio.

Visualizers

Visualizers allow generating visual models from existing source code.

Visualizers tools' pro and contra:

Pro	Contra
Strict models	Useless for analysis and design
Models consistent with code	Difficult (or impossible) to customize
Code visualization and documenting
