DRAW AN ER DIAGRAM FOR THE GIVEN SITUATION
The video rental company has several branches throughout the USA. The data held on each branch is the branch address made up of street, city, state, and zip code, and the telephone number. Each branch is given a branch number, which is unique throughout the company. Each branch has allocated staff which includes a Manager. The manager is responsible for the day to day running of the given branch. The data held on a member of staff is his or her name, position, and salary. Each member of staff is given a staff number, which is unique throughout the company.Each branch has a stock of videos. The data held on a video is the catalog number, video number, title, category, daily rental, cost status, and the names of the main actors, and the director. The catalog number uniquely identifies each video. However, in most cases, there are several copies of each video at a branch, and the individual copies are identified using the video number. A video…
Draw an EER diagram for the following situation using the traditional EER notation. A technology company provides offerings to its customers. Offerings are of two separate types: products and services. Offerings are identified by an offering ID and an attribute of description. In addition, products are described by product name, standard price, and date of first release; services are described by name of the company’s unit responsible for the service and conditions of service. There are repair, maintenance, and other types of services. A repair service has a cost and is the repair of some product; a maintenance service has an hourly rate. Fortunately, some products never require repair. However, there are many potential repair services for a product. A customer may purchase an offering, and the company needs to keep track of when the offering was purchased and the contact person for that offering with the customer. Unfortunately, not all offerings are purchased. Customers are…

Each department has unique, name and a particular employee who manages the department. Start date for the manager is recorded. Department may have several locations. A department controls a number of projects. Projects have a unique name, number and a single location. Company’s employees name, ssno, address, salary, sex and birth date are recorded. An employee is assigned to one department, but may work for several projects (not necessarily controlled by her dept). Number of hours/week an employee works on each project is recorded; the immediate Supervisor for the employee. Employee’s dependents are tracked for health insurance purposes (dependent name, birthdate, relationship to employee).arrow_forward

NSU has 3 major types of employee (faculty, secretary and OSS) with their specific role. Each faculty has many research areas and they work on monthly salary basis. Secretary also works on monthly salary basis but they have an option for overtime. Security guard salary is calculated by the number of hours they worked in a month. At the end of each month, employees are paid form the NSU account. We are also interested to store the starting date of each employee.arrow_forwardDraw an ERD for the following scenario: A department employs many employees, but each employee is employed by one department. Each employee has the following characteristics: emp_Num, emp_FName, empLName, empAdress. Each department has a code and a name. Some employees, known as “rovers,” are not assigned to any department. A division operates many departments, but each department is operated by one division. Each division has a code and a name. An employee may be assigned many projects, and a project may have many employees assigned to it. Each project has a code and a name. An assignment is characterized by a date and number of hours. A project must have at least one employee assigned to it. One of the employees manages each department, and each department is managed by only one employee. One of the employees runs each division, and each division is run by only one employee.arrow_forward
- Use the ER Diagram shown on Figure 1 to answer question 9: 9. According to the ER diagram on Figure 1, which of the following is true? 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.

An example of a derived attribute is your Grade Point Average which is calculated by adding together a score for each unit (e.g., HD=4, D=3, C=2, P=1, N=0) and dividing that by the number of units you have completed. Explain how the decision as to whether the Grade Point Average would be stored in a table or calculated would be made. You are administering a database in a large retail company that records sales at each of the company’s stores. Tuning the database to improve performance by adding indexes and optimising query execution is an important ongoing aspect of the physical database design. Which attributes in a database such as this (apart from the primary key) are likely to BENEFIT from being indexed? Which attributes would you generally avoid indexing, and why?arrow_forwardUsing the ERD diagram above, explain what would happen if the minimal cardinality was changed to “1” for Raw Materials. (i.e., the relationship becomes "raw materials are used in 1 to many items.”).

M5: Customer Coordinator sends the customer's credit card information to Credit Card Service. M6: Credit Card Service sends credit card approval to the Customer Coordinator. M7, M8: Customer Coordinator sends order request to Delivery Order Service.

He wants to know the description of each part, the color of each part, how many of each item is in stock [QOH], and how much each part costs him. BS also needs to keep track of who supplies each part, the supplier’s name, contact person, and telephone number. We know that each part in inventory has only one supplier, but some suppliers supply multiple parts to BS. Bob wants each part and each supplier to be assigned a unique identifying number.
