Examine the hierarchy for the university EER diagram (Figure 3-10). As a student, you are an instance of one of the subtypes: either UNDERGRAD STUDENT or GRADUATE STUDENT. List the names of all the attributes that apply to you. For each attribute, record the data value that applies to you.
Draw an E-R diagram for a bank. It should include at least customers, checking accounts and loans, and appropriate relationships between them.
Note: To keep this to a resonable size, you should limit yourself to at most six entities and at most eight attributes per entity.
What is the difference between a recurring group and an attribute that may take on many values?

- Prepare an E-R diagram for a Aqarat (real estate) Company that lists property for sale. The following describes this organization: The company has a several number of offices. Attributes of office include Office_Number (identifier) and Location. Each office is assigned one or more employees. Attributes of employee include Employee_ID (identifier) and Employee_Name. An employee must be assigned to only one sales office. For each office, there is always one employee assigned to manage that office. An employee may manage only the office to which she is assigned. The company lists property for sale. Attributes of property include Property_ID (identifier) and Location. Components of Location include Address, City, State, and Zip_Code.

- Create an ER model to represent the data used by the library.The library provides books to borrowers. Each book is described by title, edition, and year of publication, and is uniquely identified using the ISBN. Each borrower is described by his or her name and address and is uniquely identified using a borrower number. The library provides one or more copies of each book and each copy is uniquely identified using a copy number, status indicating if the book is available for loan, and the allowable loan period for a given copy. A borrower may loan one or many books, and the date each book is loaned out and is returned is recorded. Loan number uniquely identifies each book loan.arrow_forwardWhat is an exclusive subtype relationship? Give an example other than one shown in this book.

- Create an ER diagram that correctly describes the database for exams at Campus in Bäcksvängen in accordance with the following description: (Own assumptions must be clearly described.) Staff for various functions are involved in the exams. All staff have a full name and a unique staff code. Some people are examiners on one or more courses. A course has one name and one unique ladok code. For a course, you can add up its points based on the associated elements. One part is part of a course (for example an exam, a laboratory or project). A course can have several different parts. An element has a name, a description, a torque code, one point and two or more grades (eg: U, G, VG). An element can only belong to one course. Since the database is to process the exams, it is obvious that a part like described as an examination has an examination opportunity that is identified, among other things, by the date, start time, end time and that it is possible to calculate total writing time.

When new vehicle arrives at Holiday Travel Vehicles, a new vehicle record is created. Included in a new vehicle record are a vehicle serial number, name, model, year, manufacturer, and base cost. When a customer arrives at Holiday Travel Vehicles, he or she works with a salesperson to negotiate a vehicle purchase. When a purchase has been agreed to, a sales invoice is completed by the salesperson. The invoice summarizes the purchase, including full customer information, information on the trade-in vehicle (if any), the trade-in allowance, and information on the purchased vehicle. If the customer request dealer-installed options, they will be listed on the invoice as well. The invoice also summarizes the final negotiated price, plus any applicable taxes and license fees.
