10. Relationships and Heuristics

• Relationships provide a problem solving methodology, among other things:

  • Heuristics (trial and error experimentation), previous experience, knowledge of best practices, and a "rule of thumb" approach can help to find a solution. Design patterns also communicate the "best practice" idioms and solutions.

• For example,

  • A is a logical/physical part of B.

  • A is logically/physically contained in B.

  • A has a knowledge/awareness of B with persistence beyond a single encounter.

  • A is a member of B.

  • A communicates with B (on a regular basis.)

  • A owns or manages B.
