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,…
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. Departments have a…

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.

Staff for various functions are involved in the exams. All staff have a full name and a unique staff code. Some people are examiners on one or more courses. A course has one name and one unique ladok code. For a course, you can add up its points based on the associated elements. One part is part of a course (for example an exam, a laboratory or project). A course can have several different parts. An element has a name, a description, a torque code, one point and two or more grades (eg: U, G, VG). An element can only belong to one course. Since the database is to process the exams, it is obvious that a part like described as an examination has an examination opportunity that is identified, among other things, by the date, start time, end time and that it is possible to calculate total writing time.

- Kindly go through this. The database development starts with the requirements analysis. There are many sources for gathering requirements. One of the important sources for requirements is “user interview”. During these interviews, users are asked about what kind of a system they need. Then requirements gathered from the interviews are transformed into a data model. Assume that a database designer made an interview and created an E-R diagram as above. Write a scenario that the user described requirements as in the Library Management System case study in Chapter 3.3 of Sharma et al. (2010, p. 77) during the interview - 3.3 A case study involving a Library Management System - This case study describes a simple Library Management System.

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.
