You will prepare an ER diagram describing the schema of a University database. High Achievers University (HAU) would like you to design a database that tracks its adminis- trative operations, and helps them monitor their energy usage across campus. HAU consists of departments, research groups, and employees. For each department, the database should record the department name, and the department's unique identifier. Research groups belong to exactly one department, and the database stores the research group ID, name, and its monthly budget. Each research group has to have at least one employee working in it, and is assigned at most one room as workspace. For each employee, the University assigns a unique employee ID, and records the employee's last name, first name, telephone number, address, salary, gender, data of birth, and his/her years of service. An employee may work in zero or more research groups. An employee may be a department chair. If so, they can be the chair…Problem: Your team of Data Analysts have been asked to create a database design for the Boeing X Aircraft Company (BAC), which has two HUD (heads-up display) products: TRX-5A and TRX-5B. The database must enable managers of BAC to track blueprints, parts, and software for each HUD, using the following business rules: For simplicity’s sake, you may assume that the TRX-5A unit is based on two engineering blueprints and that the TRX-5B unit is based on three engineering blueprints. You are free to make up your own blueprint names. All parts used in the TRX-5A and TRX-5B are classified as hardware. For simplicity’s sake, you may assume that the TRX-5A unit uses three parts and that the TRX-5B unit uses four parts. You are free to make up your own part names. BAC wants to keep track of all part price changes and the dates of those changes. BAC wants to keep track of all TRX-5A and TRX-5B software. For simplicity’s sake, you may assume that the TRX-5A unit uses two named software components…
- Database design is a crucial phase during the database life cycle (DBLC).John is the CEO of a company that produces large-scale online educationpackages. The company has decided to start from scratch with a brand new database system. He has approached you to assist him specifically with the Conceptual Design. John has provided you access to their previous system and has set up interviews for you with multiple employees that use the system. John has also requested a visual representation of the data to help him get an overview. As a businessman, John must make important decisions based on reports generated by the system. A list of the required reports has been sent to you. John has also indicated that their data will be hosted across multiple sites due to thelarge amounts of data that have to be stored.Fully explain to John how you will approach the Conceptual Design stage.Your answer must refer to the situation described above.Based on the information given above, draw the conceptual EERD where you should include the enhanced features. You are required to design a database for a car championship. The requirements are as follows:In the championship, each car’s information such as the car model, the top speed and the acceleration will be stored, and it is identifiable through a unique car ID. Each car will be drove by only one driver. Each driver’s info such as the unique driver number, driver name and the experience level of the driver are stored as well. A driver may have many trainers from more experience drivers and these experience drivers would have at least one trainee who follow them. Each of these drivers are usually supported by a team which each team have a name and is identifiable through the team number. Usually, a team would have at least one driver in the race.Every race would have a specific race ID and a race name. In a race would consists of many cars and each race would have a record of the…Please written by computer source Part I - Modeling You are building a database for a comic book store customer management system. Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted. Database Specification The database keeps information about comic books, customers, orders, inventory and reviews. First, the database should…
- The administrators of Tiny College are so pleased with your design and implementation of their student registration/tracking system that they want you to expand the design to include the database for their motor vehicle pool. A brief description of operations follows: Faculty members may use the vehicles owned by Tiny College for officially sanctioned travel. For example, the vehicles may be used by faculty members to travel to off-campus learning centers, to travel to locations at which research papers are presented, to transport students to officially sanctioned locations, and to travel for public service purposes. The vehicles used for such purposes are managed by Tiny College’s TFBS (Travel Far But Slowly) Center. Using reservation forms, each department can reserve vehicles for its faculty, who are responsible for filling out the appropriate trip completion form at the end of a trip. The reservation form includes the expected departure date, vehicle type required, destination,…Based on the information given below, draw the conceptual EERD where you should include the enhanced features.
