A car-rental company maintains a database for all vehicles in its current fleet. For all vehicles, it includes the vehicle identification number, license number, manufacturer, model, date of purchase, and color. Special data are included for certain types of vehicles: Trucks: cargo capacity. Sports cars: horsepower, renter age requirement. Vans: number of passengers. Off-road vehicles: ground clearance, drivetrain (four- or two-wheel drive). Draw E-R diagram and make sure to indicate key attributes, cardinality, and participation constraints.

Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher. Abook is identified by its ISBN, and other attributes are title, price, and number of pages. Each book iswritten by one or more authors; an author writes one or more books, potentially for differentpublishers. Each author is uniquely described by an author ID, and we know each author's name andaddress. Each author is paid a certain royalty rate on each book he or she authors, which potentiallyvaries for each book and for each author. An author receives a separate royalty check for each book heor she writes. Each check is identified by its check number, and we also keep track of the date andamount of each check.TasksDesign a SQL database using the above US superstore sales data set.1.Use Visual Paradigm to draw conceptual diagram2.Use Visual Paradigm todraw ERD
The State of New York certifies firefighters through- out the state and must keep track of all of them, as well as of the state’s fire departments. Each fire department has a unique department number, a name that also identifies its locale (city, county, etc.), the year it was established, and its main telephone number. Each certified firefighter has a unique fire- fighter number, a name, year of certification, home telephone number, and a rank (firefighter, fire lieu- tenant, fire captain, etc.) The state wants to record the fire department for which each firefighter currently works and each firefighter’s supervisor. Supervi- sors are always higher-ranking certified firefighters. Construct a relational database for New York’s fire departments and firefighters.

An E-learning website needs your help to design its database. They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles. Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.
Each department runs a number of courses. The university provides a set of modules used in different courses. Each course uses a number of modules but not every module is used. A course is assigned a unique course code and a module is identified by a unique module code. A module can be used in one course only, but can be studied by many students. In addition to the module code each module unique title, start date, end date, texts (books), and assessment scheme (i.e., coursework and exam marks percentages) are also stored. Each course is managed by a member of academic staff, and each module is coordinated by a member of academic staff also. The database should also store each course unique title, and duration (in years). A student can enroll in one course at a time. Once enrolled a student is assigned a unique matriculation number. To complete a course, each student must undertake and pass all the required modules in his/her course. This requires that the database store the…
An insurance company needs to store their salespeople’s information who are selling their insurance policies. They already have a database with multiple tables, one of the tables (Salesperson) stores information about each salesperson along with the bonus percent they receive, based on the city where the insurance is sold. The table has the following fields: Salesperson(spID, spName, spBirthDate,spCitySelling, bonusPercent) spID: Unique identification number of the salesperson. spName: Full name of the salesperson. spBirthDate: Birthdate of the salesperson. spCitySelling: The city in which the salesperson is selling the insurance. bonusPercent: The bonus percent received by the salesperson based on the city in which he/she sells the insurance. Each salesperson can sell the insurance in just one city. However, for a city, there can be more than one salesperson appointed. Also, the bonus percent is fixed for each city. For example, all of the salespeople who sells insurance in…
Requirement analysis: Course evaluation must have a student, the students relation contains a unique student id, full name for each student, email address, phone number, address and date of birth. For each course, the courses contain course id, course name and credit. Each student can take many courses. For each Instructor, the instructors contain id, name and email. Each instructor can instruct many courses. For each section, the sections contain section id, year and semester. Students are able to evaluate the current courses.

A book is identified by its ISBN number, and it has a title, a price, and a date of publication. It is published by a publisher, which has its own ID number and a name. Each book has exactly one publisher, but one publisher typically publishes multiple books over time.
A Bank has many customers. Attribute for customer includes customer number, name, address (street, city, state and zip code), sex and date of birth. Customer can have multiple accounts. The bank does not allow join account (one account per customer). Type of account offer by the bank are Saving, Current and Fixed Deposit. Attribute for account are account no, account type, and account balance. Each of the account can only exist in a particular branch. Attribute for branch are branch no, branch name and address (street, city, state and zip code). Customer can open different account at different branch. Draw an ER diagram for the above situation. Identify the entity, attributes, primary key, relationship and multiplicity constraint in the ER diagram.
A library has books, journals, and periodicals that it loans to its users. All library material has an accession number which is a unique identifier and a price. In addition, a book has a title, publisher, year of publication, edition, and authors. Journals have journal name, volume number, issue number and year of publication. Each article in a journal has a title and authors. A periodical has a name and date of publication. The library keeps one or more copies of each library item (book, journal, periodical). Copies of all library material can be loaned to users. Reference-only material is loaned for 2hrs and can’t be removed from the library. Other material can be loaned for 2 weeks. For every loan, the library records the user, the loan date and time, and the return date and time. For users, the library keeps their name, address, and cell phone number. If a user loses a loaned item they are made to purchase it, however, if the user delays with the loaned item they are finned…
