BCS Practitioner Certificate in Systems Modelling Techniques
0/2 checked
A business analyst has been asked to produce a model that captures the effect of events on a single entity over time. According to the syllabus, which type of model is appropriate for this requirement?
Explanation
The dynamic model requirement is met by an entity life history showing the effect of events on an entity (or alternatively a sequence diagram realising a use case) [1]. Entity relationship models and analysis class models are data models, and process models are functionality models [1].
The exam tests the BCS Practitioner Certificate in Systems Modelling Techniques; it has been superseded by the BCS Practitioner Certificate in Systems Modelling and Development.
