Assume that the following requirements were collected: (10 marks) The museum has a collection of art objects. Each art object has a unique ID, a year (when it was created, if known), a title, and a description. Art objects must be categorized based on their type. There are three main types: painting, sculpture, plus another type called other to accommodate objects that do not fall into one of the two main types. A painting has a paint type (oil, watercolor, etc.), material on which it is drawn on (paper, canvas, wood, etc.), and style (modern, abstract, etc.). A sculpture has a material from which it was created (wood, stone, etc.), height, weight, and style. An art object in the other category has a type (print, photo, etc.) And style.

- pls help me : Draw an ER diagram according to the following requirements:Database to manage daily medical examination and treatment in the hospital (not interested in treating inpatients):- The hospital has many doctors and nurses from different departments. Each doctor and nurse belongs to only one department- The patient when he comes to the doctor will be created a patient record if it is the first visit- Each visit will be made a medical record and assigned an initial clinic. Each visit is attended by a doctor and an assistant nurse.- The doctor may ask the patient to perform tests, x-rays, endoscopy, ....- After the results are available, the patient returns to the original clinic for the doctor to read the results and prescribe medicine if any- Patients can buy medicine in the hospital pharmacy or buy it outsideDraw 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.

The outcome of this transformation will be a relational schema. The schema should have the following components: Set of required relations All the integrity constraints Submission and Evaluation: A report consisting of the problem statement, ER diagram, relational schema And implement the database using SQL should include: All the tables properly defined /created All constraints properly defined For each table, few instances of data should be entered.
- Data base systmes: Design an ER schema diagram for a sport league database to keep track of the teams and games of it. The database is organized into teams. Each team has a unique name, a unique number, and particular colors. A team may have several colors. Each team plays several games. It is desired to keep track of the result of each game. A team has a number of players, not all of whom participate in each game. Each player has a unique name, a unique number, and a particular position. It is desired to keep track of the players participating in each game for each team, the performance they played in that game, and the time played by each player in each game.Book (BookID, Price, Year, Author, Subject) BorrowLog (BID, BookID, CustomerID, DateTime) Customer (CustomerID, CustomerName, Address, City) Write the DDL script to create “smallLibrary” database with the given three tables.

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…
- Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…Material : Relational Algebra Course : Database Systems Create a Relational Algebra From Entity Relational Diagram (ERD) Below for:a) Displays books published in the last 5 years from 2020.b) Displays details of customers who have done shopping (using the Join operator)c) Displays email customers who have done shopping (using the Set operator)d) Displays the ISBN book that has never been purchased (using the Set operator)Relational Model (Logical and Physical Schema Development) The conceptual model developed in phase 2 will be transformed into a logical and physical schema using the relational data model.
