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).

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…
