//Need typed version please You are working with a database that stores information about suppliers, parts and projects. The Supply relation records instances of a Supplier supplying a Part for a Project. The schema for the database used in this question is as follows: ( primary keys are shown underlined, foreign keys in bold). SUPPLIER (SNo, SupplierName, City) PART (PNo, PartName, Weight) PROJECT (JobNo, JobName, StartYear, Country) SUPPLY (SNo, PNo, JobNo, Quantity) Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc or the words ‘PROJECT’, ‘RESTRICT’ etc . do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the name of any part that was not used on a project that commenced in 2020.

Subject: Database Topic: EERD -Based on the information given below, draw the conceptual EERD where you should include the enhanced features. [Using UML Design] 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…
c# Create a small Sports database with two tables: Team and Athlete. The Team table should include fields for the type of team (e.g., basketball), coach's name (both last and first), and the season the sport is most active (S for spring, F for Fall, or B for both). The Athlete table should include fields for student number, student first and last names, and type of sport. Use the same identifier for type of sport in both tables to enable the tables to be related and linked. Populate the tables with sporting teams from your school. Write a C# program that displays information about each team, including the names of the athletes. The data base we have provided to us just need to know how to program it in with the other guidelines given.

We need to create a database for the Circulation Department of a public library. The database will store information about the patrons, books, and circulation. It contains the following: 4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table. CHECKOUT table records the date of check-out, patron’s ID, the…
