Consider the following enterprise, which includes movies, actors, and studios that produce movies. Actors are people with normal attributes, like Id, name, date of birth, etc. Actors play in movies. A movie has the usual attributes: title, release date, director, etc. (you choose ? we do not need many). Studios are companies. A company has an address, phone numbers (typically more than one),
name, etc. Studios have additional attributes, such as the artistic director. Constraints: A movie has at least one actor, and exactly one studio makes each particular movie. Every actor played in at least one movie. Some studios may be brand new and had no time to make any movies yet. (a) Represent the above as an E-R diagram; include all relevant constraints. (b) Translate the above diagram into the relational model by supplying the appropriate CREATE TABLE statements. Note that actor's Id is a 10-digit string and a phone number is a 10 digit number that never starts with a zero. Specify these as domains in SQL. Specify all the key and foreign key constraints. Try to preserve as many participation constraints as possible. List all the participation constraints that are present in the E-R diagram, but not in its translation to SQL.
