Design an ER diagram for keeping track of information about votes taken in the U.S. House of Representatives during the current two-year congressional session.
The database needs to keep track of each U.S. STATE’s Name (e.g., Texas, New York, California) and includes the Region of the state (whose domain is {Northeast, Midwest, Southeast, Southwest, West}).
Each CONGRESSPERSON in the House of Representatives is described by their Name, and includes the District represented, the StartDate when they were first elected, and the political Party they belong to (whose domain is {Republican Democrat, Independent, Other}).
The database keeps track of each BILL (i.e., proposed law), and includes the BillName, the DateOfVote on the bill, whether the bill PassedOrFailed (whose domain is {YES,NO}), and the Sponsor (the congressperson(s) who sponsored--i.e., proposed--the bill).
The database keeps track how each congressperson voted on each bill (domain of vote attribute is {Yes, No, Abstain,…
Design a database for a worldwide package delivery company (e.g., DHL or FedEx). The database must be able to keep track of customers who ship items and customers who receive items; some customers may do both. Each package must be identifiable and trackable, so the database must be able to store the location of the package and its history of locations. Locations include trucks, planes, airports, and warehouses. 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.
Draw ER (or EER) diagram: A conceptual database design for a chain of furniture stores is needed. The following is a summary of the database requirements:
a) The chain has many different stores in various cities and states. Each STORE has unique StoreNumber, plus an Address(made up of Street, City, State, ZipCode), and a StoreManager (who is an employee). Each store is organized into a number of departments.
b) Each DEPARTMENT contains certain types of furniture (such as ‘dining’, ‘living room’, ‘bedroom’, ‘office’, etc.), and has a DeptName that is unique within each store; it also has a DeptManager (who is an employee), and a number of SalesPersons (who are employees).
c) The company employs many employees. Each EMPLOYEE has a unique SSN, plus a Name (made up of FirstName, Minit, LastName), a job (e.g. ‘store manager’, ‘dept manager’, ‘sales associate’, ‘sales person’, etc.), plus DateOfBirth, Sex, Salary, and CommissionRate. Each employee works for a particular store.

- 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.

A tutorial school is using a database to manage information about teachers, courses, and students. Each teacher is identified by staff_id, has a name, an email address, and a phone number. Each student is identified by student_id, has a name, an email address, and a registration date. Each course is identified by course_id, year, and semester. In addition, each course has a name. Each course is associated with multiple lessons. A lesson has a lesson number, a location, a date, a start-time, and an end-time. Lesson numbers are sequentially numbers, starting from 1, generated separately for each course. Each teacher teaches at least one course. Each student takes at least one course. Each course is taught by one teacher. Each course can be taken by many students.arrow_forwardMapping this class diagram to a relational database during the design phase of the Software development (don't draw ER diagram, Just tables)arrow_forward

The clinic staff consists of ten doctors, six nurses, five office secretaries, two administrative assistants and one manager. First time Patients have to visit the clinic personally and fill a registration form that contains their personal and health related information. An office secretary would then enter that information in the computer based information system. Patients may become a permanent patient (at any time) for one of the doctors at the clinic by filling up necessary forms (they are called enrolled patients) or they may choose to come walk-in for every visit. (They usually called walk-in patients) Enrolled Patients may book their appointments online or by calling, the office and one of the secretaries would then book their appointment with their doctor on a particular day/time. Any booked appointment may be cancelled up to 24 hours in advance after which the clinic…arrow_forward

A purchase order for product from a supplier has a unique order No, and a date. The order specifies one or more products and their quantities required for a product. A sales order for product to customers has a unique order No, and a date. The order specifies one or more products and their quantities required for a product The shopping mall has warehouses.
