3rd Normal Form 1.  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 (other than those implied by the primary key) are shown where appropriate. a) CLASS(CourseNo, SectionNo)   b) CLASS(CourseNo, SectionNo, Room)   c) CLASS(CourseNo, SectionNo, Room, Capacity)         [FD: Room ---> Capacity]   d) CLASS(CourseNo, SectionNo, CourseName, Room, Capacity)        [FD:  CourseNo --> CourseName; FD: Room è Capacity]   2.  The below table contains sample data for parts and for vendors who supply these parts.  In discussing these data with users, we find that part numbers (but not description) uniquely identify parts and vendor names uniquely identify vendors.   Link to view table mentioned above at http://i.imgur.com/wBlODnQ.png     a)      Convert this table to a relation (named PART SUPPLIER) in first normal form.  Illustrate the relation with the sample data in the table   b)    List the functional dependencies in PART SUPPLIER and identify a candidate key.   c)     For the relation PART SUPPLIER, identify each of the following: an insert anomaly, a delete anomaly, and a modification anomaly.   d)    Draw a relational schema for PART SUPPLIER and show the functional dependencies.   e)     In what normal form is this relation?     f)     Develop a set of 3NF relations from PART SUPPLIER.   All of this is also attached!
