Draw the ERD with appropriate mapping cardinalities for mail order database in which employees, each identified by unique employee number, first name last name and ZIP code. Employee are categorized as manager, clerk ad delivery staff. Each customer of the company is identified by a unique employee number, first and last name and ZIP code. Each part sold by the company is identified by unique part number, part name, price and quantity stock. Each order placed by a customer is taken by a clerk and is given a unique order number. Each order contains specified quantities of one or more parts. Each order has a date of receipt as well as an expected ship date. The actual ship date is also recorded. The delivery boy places the order of specified customers. There is a provision of replacing one or many fault parts to the customer but before that it must be verified by the manager.
Consider a MOVIE database in which data is recorded about the movie industry. The data requirements are summarized as follows:
Each movie is identified by title and year of release. Each movie has a length in minutes. Each has a production company, and each is classified under one or more genres (such as horror, action, drama, and so forth).
Each movie has one or more directors and one or more actors appear in it. Each movie also has a plot outline. Finally, each movie has zero or more quotable quotes, each of which is spoken by a particular actor appearing in the movie.
Actors are identified by name and date of birth and appear in one or more movies. Each actor has a role in the movie.
Directors are also identified by name and date of birth and direct one or more movies. It is possible for a director to act in a movie (including one that he or she may also direct).
Production companies are identified by name and each has an address. A production company produces one or more…
