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	Sample Value	Sample Value	Sample Value
MEMBER_NUM	214	235	214
MEMBER_NAME	Alice B. VanderVoort	Gerald M. Gallega	Alice B. VanderVoort
MEMBER_ADDRESS	325 Meadow Park	123 Rose Court	325 Meadow Park
MEMBER_CITY	Murkywater	Highlight	Murkywater
MEMBER_ZIPCODE	12345	12349	12345
INVITE_NUM	8	9	10
INVITE_DATE	23-Feb-2016	12-Mar-2016	23-Feb-2016
ACCEPT_DATE	27-Feb-2016	15-Mar-2016	27-Feb-2016
DINNER_DATE	15-Mar-2016	17-Mar-2016	15-Mar-2016
DINNER_ATTENDED	Yes	Yes	No
DINNER_CODE	DI5	DI5	DI2
DINNER_DESCRIPTION	Glowing sea delight	Glowing sea delight	Ranch Superb
ENTREE_CODE	EN3	EN3	EN5
ENTREE_DESCRIPTION	Stuffed crab	Stuffed crab	Marinated steak
DESERT_CODE	DE8	DE5	DE2
DESERT_DESCRIPTION	Chocolate mousse with raspberry sauce	Cherries jubilee	Apple pie with honey crust

Given the information in the table above:

1. Given the table structure illustrated above, write its relational schema and draw its dependency diagram. Label all transitive and/or partial dependencies. (Note: For this example, you can use the table name and attribute names as given even though they don't strictly follow the relational schema naming conventions given in the notes. You can also create a shortened version of these attribute names if it is easier to work with).
2. Break up the dependency diagram you drew in part (a) to produce dependency diagrams that are in 3NF and write the relational schema. (Hint: You might have to create a few new attributes. Also, make sure that the new dependency diagrams contain attributes that meet proper design criteria; that is, make sure that there are no multivalued attributes, and so on.)
3. Draw the Crow's Foot ERD to reflect the dependency diagrams you drew in Part (b).
