OMT Object Model
11. Similar Techniques
In chapter three ( system development context ) we already discussed some techniques serve the same puprpose as OMT's Object Model.
We will give a short overview:
- Booch method
- This method uses both class as wel as object diagrams. The class diagram resembles OMT't Object Model the most.
- Fusion (do not mix this op with Rumbaughs and Booch's new Fusion method)
- The object model used here resembles our Object Model. There however are two object models: problem domain model and system model.
- Wirfs-Brock et al.
- This method consists of two phases. To structure these phases, cards are used to model the different aspects. These cards have the same goal as our Object Model.
- HOOD
- HOOD is a hierarchical method. The diagram that is formed is the analysis phase resembles the Object Model, because it consists of parent and child diagrams with their operations. This is the same as inheritance in the Object Model.
Of course there are a lot more techniques to model the data structure of a system (e.g. ER diagrams), but we restricted ourselves to data modelling thechniques for object oriented systems. The methods mentioned above are the ones most frequently mentioned in literature and on the internet.
