2. Þraw an E/R diagram for a database recording information about teams, players, and their fans, including: 1. For each team, its name, its players, its team captain(one of its players), and the colors ofits uniform. 2. For each player, his/her name. 3. For each fan, his/her name, favorite teams, favorite players, and favorite color. 4. Remember that a set of colors is not a suitable attribute type for teams. How can you get around this restriction?

A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spreadsheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.

Construct an ER Diagram from the following case study A new established company database needs to store information about employees (identified by NIC, with salary and phone as attributes), departments (identified by dno, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company.

Design and draw an ER diagram that captures the information about the university. Consider thefollowing information about a university database: 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 startingdate, an ending date, and a budget. Graduate students have an SSN, a name, an age, and a degreeprogram (e.g., M.S. or Ph.D.). Each project is managed by one professor (known as the project’sprincipal investigator). Each project is worked on by one or more professors (known as theproject’s co-investigators). Professors can manage and/or work on multiple projects. Each projectis worked on by one or more graduate students (known as the project’s research assistants). Whengraduate 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 (potentiallydifferent) supervisor for each one. Departments have a…

A company database needs to store information about employees (identified by ssn, with salary and phone as attributes), departments (identified by dno, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company. Draw an ER diagram that captures this information.
Design a database for an airline. The database must keep track of customers and their reservations, flights and their status, seat assignments on individual flights, and the schedule and routing of future flights. Your design should include an E-R diagram, a set of relational schemas, and a list of constraints, including primary-key and foreign-key constraints.

Please give a step-by-step answer. The ER Diagram must contain the ER-Diagram Symbols. Design an EER diagram for an Hotel Management System. The hotel wants to keep track of all their employees, customers, bookings, rooms and services. They have hired you to help them design the database for that purpose. You can design your EER as you wish, but it must satisfy the following constraints: a. there should be at least one overlapping-partial specialization/generalization. b. There should be at least five regular/strong entities [excluding subclasses] c. There must be a recursive relationship. d. There must be at least one 1:1 relationship. e. There must be at least one multivalued-composite attribute. Show all important attributes, entities and relationships in order to represent a clear and complete scenario. The EER diagram should be logically accurate and realistic, representing the database of the given scenario.
