- Draw an ER diagram that captures the following information: A book identified by (unique Id number, a title and one or more authors), A library identified by (unique name and adders), A borrower has a name and a unique ID code. The library service may own several copies of a given book. A borrower can have many books on loan, but each copy of a book can only be on loan to one borrower. A borrower could borrow the same book on several occasions, but it is assumed that each such loan will take place on a different date. *In Chapter 3 of Sharma et al. (2010), you will be introduced with a case study: "This case study describes a simple Library Management System. Assume the requirements for the system were written by your client exactly in these terms: The system will manage the author's and loaner's information, and keep track of books loaned. The borrower's information includes name, address, e-mail, and phone. The author's information includes name, address, and e-mail. New books, authors and clients are entered into the system. When a client checks out a book, the system will register the date the book was loaned and calculate the days the book can be loaned. It will also calculate the date the book is due to be returned. If the borrower returns the book late, he must pay a fine based on the number of days overdue." (Sharma, et al., 77). Assume that the traditional file system is currently used in this library and a DBMS is to be developed. Discuss the advantages and challenges for the use of…Luxury-Oriented Scenic Tours (LOST) provides guided tours to groups of visitors to the Washington, D.C. area. In recent years, LOST has grown quickly and is having difficulty keeping up with all of the various information needs of the company. The company's operations are as follows: LOST offers many different tours. For each tour, the tour name, approximate length (in hours), and fee charged is needed. Guides are identified by an employee ID, but the system should also record a guide's name, home address, and date of hire. Guides take a test to be qualified to lead specific tours. It is important to know which guides are qualified to lead which tours and the date that they completed the qualification test for each tour. A guide may be qualified to lead many different tours. A tour can have many different qualified guides. New guides may or may not be qualified to lead any tours, just as a new tour may or may not have any qualified guides. Every tour must be designed to visit at least…
- Question 5: Study the scenario and complete the question(s) that follow: (The scenario is tagged on the picture.) 5.1) With the help of examples from the Azambezi River Hotel online reservation system, elaborate on the differences between functional and non-functional requirements.Draw a complete ER-diagram for the following case. A lecturer (having an ID, name and room number) is responsible for organizing a number of course modules. Each module has a unique code and also a name and each module can involve a number of lectures who deliver part of it. A module is composed of a series of lectures and sometimes lectures a on a given topic can be part of more than one module. A lecture has a time room and date and is delivered by a lecturer and a lecturer may deliver more than one lecture. Students, identified by number and name, can attend lectures and a student must be registered for a number of modules. We also store the date on which the student first registered for that module. Finally, a lecturer acts as a tutor for a number of students and each student has only one tutor. Also show relational database schema including Primary and Foreign key constraints. (Please draw this on a paper)Do not use any Al to do this question. Please show the diagram at the end. Question Lekker Living is a new backpackers that recently opened close to Stellenbosch.
