Tips for the Case Study: Read the narrative carefully, as it fully describes the ‘scenario’ for the case study, defines the basic business model involved, and identifies the primary ‘players’ in the case study; e.g. entities, attributes, and actors. Remember that the swim lane diagram is designed by the Business Analysts, to address the organizational problem and requirements, establish the process model, and to identify ‘who needs & does what’. The ERD diagrams are then developed by the Systems Analysts, to establish what types of IT systems are needed and how the databases need to be structured. The focus with the ERD is to identify the Entities and their attributes, and establish the relationships and meaningful connections between the entities.
