Please answer ALL of the questions in my homeworkd:”DATA BASE MANAGEMENT SOLUTIONS BOOK – I really need to answer this question ASAP:Exercise 20.4 The Globetrotters Club is organized into chapters. The president of a chapter can never serve as the president of any other chapter, and each chapter gives its president some salary. Chapters keep moving to new locations, and a new president is elected when (and only when) a chapter moves. This data is stored in a relation G(C,S,L,P), where the attributes are chapters (C), salaries (S), locations (L), and presidents (P). Queries of the following form are frequently asked, and you must be able to answer them without computing a join: “Who was the president of chapter X when it was in location Y ?”1. List the FDs that are given to hold over G.2. What are the candidate keys for relation G?3. What normal form is the schema G in?4. Design a good database schema for the club. (Remember that your design must satisfy the stated query requirement!)5. What normal form is your good schema in? Give an example of a query that is likely to run slower on this schema than on the relation G.6. Is there a lossless-join, dependency-preserving decomposition of G into BCNF?7. Is there ever a good reason to accept something less than 3NF when designing a schema for a relational database? Use this example, if necessary adding further constraints, to illustrate your answer.
