The smaliest unit of application data recognized by system software is a: A) field. data type. column 21. (20 Points) The relation PART_SUPPLIER (Part No, Description, Vendor Name Vendor Address, Unit Cost) below contains sample data for parts and for vendors who supply those parts. The composite primary key of this relation is Part No and Vendor_ Name. The meaning of each row in PART_SUPPLIER relation (see below) is that a particular vendor supplies a particular part at a certain unit cost In discussing these data with users, the database analyst found that part numbers (but not descriptions) uniquely identify parts, and that vendor names uniquely identify vendors. Moreover, a single vendor may supply multiple parts and a single part might be supplied by different vendors. Please answer each of the following questions: a. Draw a relational schema for this relation and show the functional dependencies. b. In what normal form is this relation? c. If this relaton is not in third normal form, normalize the relation so the the resulting relations are in third normal form.
