- Considering the un-normalized relational table PROJECT below: PROJECT (Project Title, EmpeName, ManagerName, Location, Hours Work, ManagerPhone) The attributes of PROJECT table satisfy the following properties: Each project has many employees, Each employee may involve in one or more projects, Projects are managed by managers; there are many managers in the company, hence a project may be assigned to any one of the managers, but each manager manages only one project. Each project is located in a specific location, The number of hours an employee works at each project is determined by a project title and the name of an employee. Each manager has a telephone number. Normalize the relational table PROJECT into a minimal number of relational tables in BCNF.

Each order contains quantity of books required, mode of delivery and the order date. The detail captured about a book includes the ISBN number, the title, author and publisher of the book. Books may be borrowed by registered members, who are identified by a borrower number. The library also keeps members’ name, email address and phone number. A member may borrow a maximum of two (2) books on each occasion. A supplier delivers one or more books orders to the library. The supplier’s name, address and telephone contact is kept by library.

A) For each employee, we will keep track of either the employee name or the unique employee ID. B) For each department, we will keep track of either the unique department ID or the department location. C) Each employee reports to exactly one department. A department may have many employees reporting to it, but it does not have to have any. D) None of the above. Answer: EmpID EmpName EMPLOYEE Reports To Figure 1 DeptID DEPARTMENT DeptLocationarrow_forwardEach publisher has a unique name; a mailing address and telephone number are also kept on each publisher. A publisher publishes one or more books; a book is published by exactly one publisher. A book is identified by its ISBN, and other attributes are title, price, and number of pages. Each book is written by one or more authors; an author writes one or more books, potentially for different publishers. Each author is uniquely described by an author ID, and we know each author’s name and address. Each author is paid a certain royalty rate on each book he or she authors, which potentially varies for each book and for each author. An author receives a separate royalty check for each book he or she writes. Each check is identified by its check number, and we also keep track of the date and amount of each check. As you develop the ERD for this problem, follow good data naming guidelines.arrow_forward
