A winter sports shop rents out equipment such as skis, boots and poles. A database is required to manage the rental equipment and record any repairs. The E-R diagram below shows the relevant entities and the relationships between them. The following conceptual schema describes the entities and their attributes. The relationships are as given on the diagram. Item(Itemcode, purchased, condition) Type(Manufacturer, CatNo, description) Repair(JobNo, work) Staff(EmpNo, name, address, position) Transform the above E-R model into a logical schema (i.e. a set of tables), clearly indicating which attributes are primary or foreign keys. Clearly explain your reasoning, including discussion of the options available for representing relationships.
