Transform the following entity relationship diagram into a relational schema.
What are three signs that a surrogate key should be generated for the primary key of a relation instead of using the main key?
Table 4-8 shows a portion of a shipment table for a large manufacturing company. Each shipment (identified by Shipment#) uniquely identifies the shipment Origin, Destination, and Distance. The shipment Origin and Destination pair also uniquely identifies the Distance.
Question:
a. Develop a diagram that shows the functional dependencies in the SHIPMENT relation.
b. In what normal form is SHIPMENT? Why?
c. Convert SHIPMENT to third normal form if necessary. Show the resulting table(s) with the sample data presented in SHIPMENT.

- For developing our queries, we will be using the following relational schema: Student(SID, name, username, major) Course(cname, description, department, weight) Offering(OID, cname, year, term, duration) Enrolled(SID, OID, grade) A course relation is the generic description of a course which is offered by a department. The offering relation is the specific instance of a course being taught in a given term, and is the entity which will be associated with the student enrollment. Students are enrolled in these offerings and achieve a mark.

- Create a relational diagram for the database using crow’s foot notation. The ERD should include all the entities, relationships, and connectivity where applicable. 4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table. CHECKOUT table records the date of check-out, patron’s ID, the identifier of the book copy…arrow_forwardWhat are three advantages of using a surrogate key rather than the main key to access a relation instead?arrow_forward
