- Using a graphics program, develop an entity-relationship diagram for a database application for an Internet bookstore where students buy textbooks from a salesperson and receive invoices for their purchases. Use Figure 5.5 as a guide.Integrate any programming language to mySQL with the implementation of Database Normalization and Creation of ER Model. What should I expect? 1. User login interface 2. An interface where I can input my details. (User registration form, Freshman Application Form, Credit Card Application Form, Bank Account Opening Form, and etc.) These are just samples, you can think of your own, of course. 3. From one whole big interface of registration form or any above-mentioned items, I should see the database normalization implemented from whole big table (1NF) to 3NF. The expectation is that the database should have 1NF table and lastly the 3NF tables.Imagine you are asked to design a simple database for an airport. You should accommodate for: - Passengers, their personal and their booking information - Airplanes, their cargo and their destinations - All available destinations and their distances. Please create or sketch the relational model of such database structure, including the relationships and cardinalities. The model should have at least 5 entities. Write SQL queries for the designed database which will return: - All people on the same flight - All planes on the same destination - If the sum of all cargo weight on the plane is under a threshold.
- Subject: Database Topic: EERD Please use UML Modelling Notation. (Don't use Chen’s Notation or Crow’s Feet Notation) -Based on the information given below, draw the conceptual EERD where you should include the enhanced features. 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…114. A tool that can help designers understand the dependencies of database structures is a: a. dependency graph. b. data model. c. graphical display. d. None of the above is correct.Create a relational database design for the following data model
- Course: DataBase Management System Question no 01: Note: Please make sure that all the points/rules must be implemented. Draw the ERD Diagram to create relational model corresponding to the described Scenario. The loan office in a bank receives from various parties, requests to investigate the credit status of a Customers. Each credit request is identified by a Request ID and is described by a Request Date and Requesting party Name. The loan office also received results of credit checks. A credit check is identified By a credit check ID and is described by the credit check Date and the credit rating. The loan office Matches credit requests with credit check results. A credit request may be recorded before its result Arrives; a particular credit result may be used in support of several credit requests. Draw ERD for this Situation. Requirements: ER Diagram of system implemented in tool such as Sqlyog & Draw.io (Available online). Note: DRAW ERD ASAPPart 3 5. Database design often involves decisions about the storage of attributes. For example a Telephone Number can be stored as a one attribute or split into three attributes (one for each of the three hyphen-delineated groups of numbers in a Telephone Number (XXX)-XXX-XXXX, I.e (123)-456-7890). However, Telephone Number is usually stored in one attribute. The decision is usually based on how the database will be used. This exercise asks you to think about specific situations where dividing the Telephone Number is useful. List and describe the different situations, give examples.Here is the database design for the personnel data: employee(id, name, address) employeeMap(id, confidentialId) empSalary(confidentialId, salary) The role 'Clerk' would be granted SELECT, UPDATE, DELETE to employee table and granted SELECT to empSalary table. While the clerk can see salary information for any statistical analysis (e.g. average salary computation), he has no idea which employee the salary is for. The role 'Administrator' is granted rights on all three tables; using the confidentialId in the employeeMap table, she has access to salary data for individual employees too. A SQL query that the administrator can use to access all employee fields is: select e.id, e.name, e.address, es.salary from employee e inner join employeeMap m on e.id = m.id inner join empSalary s on m.confidentialId = s.confidentialId; Can you draw a database schema?
- Draw an E-R diagram for the description below. Suppose that you are asked to model a database including all pharmaceutical companies, their drugs, and all pharmacies. Each pharmaceutical company is identified by its name and has a phone number. For each drug, the trade name (e.g., Acetaminophen) and formula must be recorded. Each drug is sold by only one pharmaceutical company, and the trade name identifies a drug uniquely from among the products of that company. If a pharmaceutical company stops production, we do not need to keep track of its products any longer. Each pharmacy has an identifier name, address, and phone number. Each pharmacy sells several drugs. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another.Design an ER schema 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 include the Region of the state (whose domain is {'Northeast', 'Midwest', 'Southeast', 'Southwest', 'West'}). Each CONGRESS_PERSON in the House of Representatives is described by his or her Name, plus the District represented, the Start_date when the congressperson was first elected, and the political Party to which he or she belongs (whose domain is {'Republican', 'Democrat', 'Independent', 'Other'}). The database keeps track of each BILL (i.e., proposed law), including the Bill_name, the Date_of_vote on the bill, whether the bill Passed_or_failed (whose domain is {'Yes', 'No'}), and the Sponsor (the congressperson(s) who sponsored that is, proposed the bill). The database also keeps track of how each congressperson voted on…Design an ER schema for keeping track of information about votes taken in the U.S. House of Representatives during the current two-year congressional session.
