The database is for a portion of a healthcare organization that tracks the tests performed on patients. The details are given bellow: 1. Each doctor has a doctor ID (unique), name, and specialty. 2. Each patient has a patient ID (unique), name, address, and one or more symptoms. 3. The organization has the ability to perform a variety of tests. Each test has a test ID (unique), name, description, and cost. 4. Each time a test is performed on a patient, the database shall record the date of the test, the result of the test, and the doctor who performed the test. It should be noted that a particular test is never performed on a particular patient more than once on any given day.

Consider a MAIL_ORDER database in which employees take orders for parts from customers. The data requirements are summarized as follows: o The mail order company has employees, each identified by a unique employee number, first and last name, and Zip Code. o Each customer of the company is identified by a unique customer num, first and last name, and Zip Code. o Each part is identified by a unique part number, a part name, price, and quantity. o Each order placed by a customer is taken by an employee and is given a unique order number. Each order contains specified quantities of one or more parts. Each order has a date of receipt as well as an expected ship date. The actual ship date is also recorded. Design an Entity-Relationship diagram for the above environment. Please indicate Cardinality Constraints and Participation Constraints

Q. Suppose we want to develop a browser-based training system to help people prepare for such a certification exam. A user can request a quiz for the system. The system picks a set of questions from its database, and compose them together to make a quiz. It rates the user’s answers, and gives hints if the user requests it. In addition to users, we also have tutors who provide questions and hints. And also examiners who must certify questions. List down the functional requirements of the above said system? Use Form based method for specifying “Make Quiz” functional requirement.
Suppose we have a database for an university. The requirements are as follows: • Professors have an SSN, a name, an age, a rank, and a research specialty. • Projects have a project number, a sponsor name (e.g., NSF), a starting date, an ending date, and a budget. • Graduate students have an SSN, a name, an age, and a degree program (e.g., M.S. or Ph.D.). • Each project is managed by one professor (known as the project’s principal investigator). • Each project is worked on by one or more professors (known as the project’s co-investigators). • Professors can manage and/or work on multiple projects. • Each project is worked on by one or more graduate students (known as the project’s research assistants). • When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one. The FDs for the above requirements are given as, • PSSN →…
Suppose you are given a data set that classifies each sample unit into one of four categories: A, B, C, or D. You plan to create a computer database consisting of these data, and you decide to code the data as A = 1, B = 2, C = 3, and D = 4. Are the data consisting of the classifications A, B, C, and D qualitative or quantitative? After the data are input as 1, 2, 3, or 4, are they qualitative or quantitative?
Here's a situation to mull over: two students are interested in enrolling in the same class, but there's only room for one of them. What is it about a database that makes it so they can't sit together?

Your task is to develop a database, in order to keep information on all sales at a motorcycle dealership. The database will include information on motorcycles, salespeople, sales, and customers. We assume for simplicity that the dealership sells only new motorcycles and that all motorcycles are produced by the same manufacturer. Each kind of motorcycle is called a model, and it has a unique model number. For each model, you want to store also its name, engine size in cubic centimeters (cc) which is an integer number, and the date when this particular model was introduced. For each salesperson, you want to store their employee ID number, first name, middle initial, last name, and the date when the employee was hired. For each customer, you want to store a customer ID number, first name, middle initial, last name, address information (city, state, and zipcode), phone number (given in standard US format), and e‐mail address. Assume that you do not have a zip code table available. Each…
