You have been called upon to do some conceptual data modeling for Purdue Summer Concert Series (PSCS). Purdue Summer Concert Series (PSCS) business scenario: A concert season indicates a period when a series of concerts are performed. The attributes of concert season should include at least season ID and opening date. Season ID uniquely identifies each concert season. A concert is a performance that consists of one or more compositions. The primary key of concert is concert number. Another attribute is concert date. The composition entity keeps records the compositions to be performed in each concert. Information tracked on each composition includes at least composition ID (primary key), composer name (last name, first name), and composition name. Conductors conduct concerts. The PSCS tracks conductor names (last name, first name) and conductor IDs. Conductor ID uniquely identifies each conductor. Soloists perform compositions during concerts. The attributes for soloists are at least soloist ID (primary key) and soloist name (last name, first name). Each composition may need multiple soloists, or may not require any soloists. A soloist may perform multiple compositions, or may not perform any compositions. In each concert season, at least one or more concerts are scheduled. A particular concert is scheduled in only one concert season. For each concert there is one and only one conductor. A conductor may conduct many concerts, or may not conduct any at all. A concert includes the performance of one or more compositions. A composition may be performed at one or more concerts, or may not be performed at all. Create an ERD based on the scenario. . Clearly show all other attributes of all entities in the ERD. If the scenario does not specify an identifier, make one for that entity. Show all cardinalities. Please write down any assumptions you make
