When modelling a real-world phenomenon, it can often be useful to have multiple descriptions of the phenomenon, each expressed using a different modelling approach or representation . Different representations such as entity-relationship modelling, data flow modelling and use case modelling allow analysts to describe different aspects of real-world phenomena, thus providing a more thorough understanding than if a single representation were used. Researchers working with multiple representations have approached the problem from different directions, resulting in a diverse and potentially confusing set of terminologies. Relative Resource |
