📝§ Software Modeling

Modeling does not necessarily involve building programs and running simulations. Sometimes, it’s just writing text explanation, drawing a diagram or a table.

Master models:

• Business model (TODO)

• Domain model—describe the problem domain regardless of your solution

  • For domain modeling, beware of adding technical details

• Design model—describe designed solution

• Code model—the code of actual implementation

Tips

• Question first and model second

• When modeling, pick important details and ignore the rest

• Use simple notations

• Put legend on diagrams

• Avoid arrowheads on connectors

• Use hand-drawn diagrams to convey a feeling of casual and temporary
