ENTITY RELATIONSHIP MODELING

Suppose you have been asked to design a database for a small, independent store that rents Videogames. Your database should deal with data associated with Videogames, customers, rentals, etc. Think about the essential data needs of the store, and then g at least 5 entity sets) based on your thoughts. Do NOT include attributes in your diagram. Instead, list them in the format shown for the (library) case study discussed in class (and shown on the slides). For each entity, mark the attributes that make up its primary key and alternate keys using the notation used in ER Modeling. Include a few comments to explain your design decisions. Note that there is no single right answer to this question, although some answers may be better than others. (30 Points)
