A taxi company would like to provide an online service for customers to book a trip and for taxi drivers to check their upcoming trips. A database needs to be created to store customer data (name, address, email, telephone number) and trip information (pick up and drop off address and pick up time and date). Furthermore, your database should contain driver information (name and license plate). Each trip must be assigned to exactly one driver (and trips for a driver must not overlap). Customers who are not registered yet need to register (providing their address, phone number, email address, and credit card information). A registered customer should be able to book a trip, i.e. provide the pick-up address and time as well as the drop-off address via a graphical user interface. Customers should also be able to view their trips and cancel them if needed. All these operations are only possible after a customer signs in (which means they must be registered). Each new trip must be confirmed…
Task #1 – Identification of dependencies We learned about two types of functional dependencies, Partial Dependency and Transitive Dependency, and they are critical clues for the identification of tables. In this task, we will practice how to identify the two types of dependencies, so that we can improve the results to new tables. Below is a list of attributes of a dataset. However, the attributes still have some functional dependencies, which means you can create more tables by separating some field(s). Order_ No Product_ No Product_ Description Product_ UnitPrice Customer_No Customer_ Phone Customer_ Address Order_ Date Shipping_ Address Order_ Qty Which partial dependency does this dataset have? Identify the partial dependency using the format in the example below. Example) Partial Dependencies: (ProjectNum ? Proj_Name) (Emp_Num ? Emp_Name, Job_Class) Then, which transitive dependencies does this dataset have? Identify the transitive dependencies…
Consider a PUBLICATION COMPANY database in which data requirements are summarized as follows: Every topic should contain name, code and research area. The topics can have several reports and the reports may contain several topics in them. The report should have a title. A department can publish more than one report. A report can be published only by a single department. The department must have its name and address. Reports can be written by many contractors and contractors can write many reports. Each contractor should have name and address. A publication can include several topics and a topic can be present in more than one publications. A publication must have its title and code. One department can have many publications and a publication can be made only by one department. Construct an E-R diagram (based on a Chen's model) to represent the above requirements. Make sure you include all appropriate entities, relationships, attributes, and cardinalities.
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…
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?
Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality. Swing Jazz Club The Swing Jazz Club teaches swing and jazz dancing and offers both private and group lessons. Swing Jazz charges $60 dollars per hour for a private lesson and $10 dollars per hour for a group lesson.…
The objective is to create a system that allows you to completely manage the functions of thecompany through an optimal design of the data model, to be adapted to a system connected to aSQL database. StatementThe pharmacy chain “Recetas Rayos X” needs a system to manage information about its operations, such as the purchase, sale and administration of medications, other patients and who prescribed them.a medicine. The information that must be stored is the following:1. Patients are identified by the RUT and the name, surname, date of birth, email,address, several telephone numbers and pension system.2. There are various health provisions, both social and private, and they are correctly codified.3. Doctors are identified by the RUT. For each doctor you have to store the first name, last name,date of birth, specialties and years of practice.4. There are various specialties which are adequately codified.5. Each pharmaceutical company is identified by a code, the name and a telephone…

Please draw an EER diagram for the bank DB system. It requires to design & plan & document a bank system. Your EER model must include supertype and subtypes inheritance associations based on your initial ER model. Relationship constraints and completeness rules (discussed in the EER module) must be included. Requirements: Metadata: define what attributes (data) represent an object (i.e. account type) and data properties (data types, valid range of values, required vs. optional, etc.) Entities (objects): Account owner, dependent (joint family), Checking account, Savings account, Money Market account, loan account, or other banking objects, online account, etc. (suggestion: Define at least 10 entities) Relationships: customer deposit or withdraw money with account, and more. Identify the possible entity sets and their attributes, the relationships among the attributes.
