4. Suppose you are given the following business rules that will form the basis for a database design. The database must enable the manager of a company dinner club to mail invitations to the club's members, to plan the meals, to keep track of who attends the dinners, and so on. Because the manager is not a database expert, the first attempt at the "database" uses the following structure. Draw its dependency diagram and identify all dependencies (including all transitive dependencies). Attribute name MEMBER NUM MEMBER NAME MEMBER ADDRESS MEMBER CITY MEMBER ZIPCODE INVITE NUM INVITE DATE ACCEPT DATE DINNER DATE DINNER ATTEND DINNER CODE DINNER DESCRIPTION ENTREE CODE ENTREE DESCRIPTION DESSERT CODE DESSERT DESCRIPTION

A student basketball club wants to keep track of their players, games, and teams for the season. The club currently has several teams, but players can only play on one team during the season. Multiple games will be played throughout the season, and each team will participate in multiple games, each against a different team. From this information, create an entity relationship diagram for a database that would help the basketball team tracks the season.

Q3. Suppose you are given the following business rules to form the basis for a database design. The database must enable the manager of a company dinner club to mail invitations to the club's members, to plan the meals, to keep track of who attends the dinners, and so on. Each dinner serves many members, and each member may attend many dinners. A member receives many invitations, and each invitation is mailed to many members. A dinner is based on a single entree, but an entree may be used as the basis for many dinners. For example, a dinner may be composed of a fish entree, rice, and corn. Or the dinner may be composed of a fish entree, a baked potato, and string beans. Because the manager is not a database expert, the first attempt at creating the database uses the structure shown in the table below: Attribute Name MEMBER_NUM MEMBER_NAME MEMBER_ADDRESS MEMBER_CITY MEMBER_ZIPCODE INVITE_NUM INVITE_DATE ACCEPT_DATE DINNER_DATE DINNER_ATTENDED DINNER_CODE DINNER_DESCRIPTION Sample Value…
