Design a database for an airline. The database must keep track of customers and their reservations, flights and their status, seat assignments on individual flights, and the schedule and routing of future flights. Your design should include a set of relational schemas, and a list of constraints, including primary-key and foreign-key constraints. Please note that an E-R diagram is not required.

- 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 outsideTask 1: ER diagram for give scenario Consider building a database for a shopping mall with requirements as follows: Each product of the shopping mall has a unique project No, and also has a name, a supplier name, a category, a purchase price and a selling price. Products need to be supplied from suppliers. Each product has one supplier, but a supplier may supply many products for the shopping mall. Each supplier has a supplier name and address. 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.

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…
- 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 an ER…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. 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. Producer Pharmacy medicines The pharmacy contains employees, certain medicines customers and patients Date Name Customers age pharmacy sex employees Commercial Record Address Location Salary NameProblem Statement: You are the CTO of a startup based out of Arlington, VA that needs to setup a database to keep track of the details of the customers: last name, first name, customer ID, street address, customer star rating (a rating on a 1– 5 scale, with 5 being best, representing the type of customer) and phone number. It also needs to keep track ofsimilar information for suppliers as well (although instead of supplier first and last name, there will just be a suppliercompany name). The database should maintain the data on products that are offered. Information about whichproduct is offered by which supplier should also be maintained. Finally, which customers have purchased whichproducts should also be tracked (note that we are only interested in which customers bought which product, but notconcerned about the date or how many were bought). 1.1 Business Rules: Assumptions for the business model are as follows:•Only customers that have purchased one or more products will exist in…
- You are to design a Hospital database. So before creating the database, your task is to draw the ER diagram based on the following data collected and analyzed: A hospital will have a name, unique id, multiple helpline numbers (one for doctor's appointment, one for ambulance, one for bill information and one for other services' info) and locations. A hospital may have more than one location as it may have different branches and each of the locations will have a building no., street address, road no. and city name. A patient will have a name, unique ID, may have more than one phone number, age, height, weight and symptoms. A patient takes an appointment in a hospital and the appointment date is recorded. A patient may have an attendant. An attendant will have his/her name, contact numbers and relationship with the patient as a record in the database. Due to the covid situation, the hospital authorities will only allow 1 attendant with 1 patient.Computer Science 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.

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…
- If you sell a house more than once, it is treated as different "property" for each sale. Draw an entity-relationship diagram and write a database design outline. Q2. Law Office: You are trying to automate the records for your uncle's law firm. Multiple attorneys work for the firm, and for each of them you want to store their first name, last name, date hired, hourly billing rate, and date promoted to partner (blank if the attorney is not a partner).
