Pass 5a Read the following narrative: Pete’s Pools have a number of swimming centres. Each centre has a name, establishment date, and a description. Clients (who have an ID and name) can join one or more of these swimming centres. As a client joins a centre, the date that the client joined is to be recorded. • Draw an ERD based on this case study. Fully expand all M:M relationships into M:1 relationships. Do not introduce any surrogate keys. The ERD may be neatly hand drawn or can be created in a package such as Visio or draw.io. The symbols in the ERD must conform to the symbols used throughout all ERD lectures this semester. Clearly indicate strong and/or weak entities, all identifiers and all relationship names. Mehr sehen
