Ņ 5. Table 4-5 shows a shipping manifest. Your assignment is as follows: a. Draw a relational schema and diagram the functional dependencies in the relation. b. In what normal form is this relation? + c. Decompose MANIFEST into a set of 3NF relations. d. Draw a relational schema for your 3NF relations and show the referential integrity constraints. TABLE 4-5 Shipping Manifest 00-0001 Boston Brazil 39 Shipment ID: Origin: Destination: Ship Number: Item Number 3223 3297 Type BM BM Description Concrete Form Steel Beam Shipment Date: Expected Arrival: Captain: Weight 500 87 Quantity 100 2,000 Shipment Total: 01/10/2010 01/14/2010 002-15 Henry Moore TOTALWEIGHT 50,000 174,000 224,000
For each of the following relations, indicate the normal form for that relation. If the
relation is not in third normal form, decompose it into 3NF relations. Functional
dependencies are shown where appropriate.
a) CLASS(CourseNo, SectionNo)
b) CLASS(CourseNo, SectionNo, Room)
c) CLASS(CourseNo, SectionNo, Room, Capacity)
d) CLASS(CourseNo, SectionNo, CourseName, Room, Capacity)
Map the ER diagram below to a set of relations (i.e., relational schema). Underline the primary key attributes of each relation. Indicate referential integrity constraints using arrows. An arrow from an attribute A to an attribute B represents that A references
