Given a database consisting of one first normal form relation SECOND with attributes A, B, C, D, E, and the functional and multi-valued dependencies as well as the functional and the multi-valued dependency diagram as follows: SECOND Functional Dependencies (AB-C,C B Multivalued Dependencies C-- D, C->-> E; Dependency Diagram 1. 2. 3. What is the key for SECOND? What is the highest normal form this relation is in? Normalize the relation into BCNF by giving its relation names, their attributes with primary keys as showing above Normalize the result in the third question into the fourth normal form by giving its relation names, their attributes with primary keys underscored and foreign keys pointing to the corresponding attributes properly and its dependency diagrams as showing above 4
