Draw an E-R diagram for the description below.
Ebony and Ivory, a piano manufacturer, wants to keep track of all the pianos it makes. Each piano has an identifying serial number and a manufacturing completion date. Each instrument represents exactly one piano model. Each piano model has an identification number and a name. Over time, the company often manufactures thousands of pianos of a certain model, and the model design is specified before any single piano exists. Ebony and Ivory employs piano technicians who are responsible for inspecting the instruments before they are shipped to the customers. Each piano is inspected by at least one technician (identified by their employee number). Each technician has a set one or more specialties. Some technicians may not be responsible for inspection jobs. For each separate inspection, the company needs to record its date and a quality evaluation grade. The piano technicians have a hierarchy of reporting relationships: some of them have…

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_forwardUse the ER Diagram shown on Figure 1 to answer question 9: 9.

- Draw the EER diagrams for the following problems using UML notation, Crow’s Foot notation and Chen notation: A large organization has several parking lots, which are used by staff. Each parking lot has a unique name, location, capacity, and number of floors. Each parking lot has parking spaces, which are uniquely identified using a space number. Members of staff can request the use of a parking space. Each member of staff has a unique number, name, telephone extension number, and vehicle registration number. The majority parking spaces are under cover and can be allocated for use by a member of staff for a monthly rate. Parking spaces that are not under cover are free to use when available. Up to twenty covered parking spaces are available for use by visitors to the company. However, only members of staff are able to book out a space for the day of the visit. There is no charge for this type of booking, but the member of staff must provide the visitor’s vehicle license number.…arrow_forwardDraw 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…arrow_forwardConstruct an ER_Diagram for NSU Employees who are identified by a unique id number. 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_forward
