Questions 1. Create a database to keep track of books, authors, publishers, and the employees that work with each publisher. The database also keeps information about the jobs that employees can do at a publishing company. An Excel spreadsheet Assignment1Data.xlsx containing the data to be stored at creation (initial load) is provided. There are six tables: Authors, BookAuthor, Books, Employees, Publishers, and Jobs. Each table must have a primary key, relationships between tables must be defined, and relationships must enforce referential integrity. The following guidelines are given about the tables. a. Authors are in Canada and each one has an Id, first name, last name, phone, postal code, province, sex, salary, birth date and a book subject. The Id is the primary key. b. For each book, we keep track of the title Id, the title of the book, publisher, price, advance for the author, year-to-date sales (quantity sold to date), and the publication date. The primary key is the titleId. c. Several authors can publish a book. Information about authors and the book in which they were an author stored in the BookAuthors table. The database also keepstrack of the ordering of author names and how often each author is paid a royalty. The primary key for this table is composite, comprising of the author Id and the title Id of the book authored. d. For each publisher, we keep track of the publisher Id (which consists of 4 digits), name, city, state, and country. The publisher Id is the primary key. e. Employees work with specific publishers. The database keeps track of employee first name, middle initial, last name, job Id, job level, publisher with which they work and their hire date. Several employees can work for the same publisher and may have the same job id. Employees are identified by their employee Id (empId). f. The jobs that employees do are stored in the Jobs table. The database keeps track of the job Id, description, min job level required for this position. A job is identified by the Job Id. 2. Choose datatypes and properties that are most appropriate for each field. For instance, names must be text, dates must be date/time and so on. Also note the following: a. Make all fields required, except for employee middle initial and publisher state (since some countries do not have states). b. Include a validation rule and text for book prices: Price must be greater than $0. c. Assume that the following fields only allow data having the same structure/format as the given initial data. Add an appropriate Format and/or Input mask for the following fields. Also set any other applicable property for the fields and any other field based on the given data. i. titleId of books ii. publisherId iii. Author phone iv. Author postal code v. Books publication date d. Include a lookup for sex field, so that the domain is limited to F, M, or U. 3. Create the following relationships. A lookup must be included for each foreign key. a. A book may have many authors / books have an author b. An author may have several books / books may have several authors c. A book has a publisher / a publisher may be the publisher for many books d. An employee works with a publisher / a publisher may have many employees e. An employee has a job / a job may be done by many employees 4. Add some data manually as follows: a.
