Phase-1 (Macro Process): OO Analysis

What is OOA?

• To analyse and globally define the classes and objects found in the vocabulary of the GEANT4 problem domain. The user requirement document was the source of vocabularies.
• To build real-world models, using an OO view of the detector simulator.

Goal:

• To identify all major objects in the problem domain, including all data and major operations that will be needed to carry out the system functions.
• To produce central models of class relations and interactions.
• To identify clusters of classes that are themselves cohesive, but are loosely coupled relative to other clusters.

Major Products:

• Class diagram - analysis phase
• Scenario (Object/Interaction) diagram - analysis phase
• Class category diagram

Period:

• February 1994 ~ April 1995

Note:

• A blurred boundary between analysis and design.
• Not much codings execpt prototyping of classes. Most time for design works and decisions.
