Unit 01 - Modeling Data and Business Processes

Question 1

What are the guidelines of modeling?

Answer 1

1. Correctness
   
   • Usage of allowed modeling primitives and combining them according to predefined rules (syntactic correctness)
   • Model has to be formally correct and consistent with the real world (semantic correctness)
2. Relevance
   
   • Only interesting parts of the universe of discourse are reflected in the model
3. Economic efficiency
   
   • Trade off between benefits and costs
4. Clarity
   
   • Model must be understood by the model user (highly subjective)
5. Comparability
   
   • Consistent utilization of a set of guidelines in a modeling project (e.g., naming conventions)
6. Systematic design
   
   • Clear separation between models in different views
   • Definition of mechanisms for the integration of views
