Make a payroll system depending on your designed/created database. The system should be able to compute for the following: a) gross pay (number of days worked x rate per day); b) tax ( 5% if the gross salary is < 30,000: 7% if > 30,000 but <= 50,000; 10% if > 50,000); c) other fixed deductions which should be in your database (like SSS and Pag-ibig); c) net pay (gross pay - all deductions). You could add other process depending on your created/designed database. Display the database before and after update. Design your own GUIs (input/output windows).

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…
Database logs may be used for any of these two functions in the overwhelming majority of instances. Find out more information on them:
Database Design [Image below] Before essential oil products are marketed, testing is carried out based on the production batch of each essential oil. This is done to maintain the quality and content of the constituents in the essential oil. Where the Test Percentage Content must reach the Minimum Percentage Content standard for each constituent. If there is one type of constituent that does not meet the minimum standards, the batch will not be marketed because it does not meet the quality standard. 1. If recording the results of each testing process is still done manually, in your opinion, please explain which approach is suitable between Centralized and View Integration for collecting requirements. 2. What Fact Finding methods will you choose to obtain information related to the development of a database system to record the testing process, and explain the reasons for choosing it.

JoziCleaners is local cleaning service that is looking to upgrade their current operations by making use of a database to keep track of the teams, houses, clients and billings of each client per/week. Each house is cleaned by one or more teams. A team goes out to a particular house on a certain day of the week. Each cleaning team has a team leader. Every cleaner eams R150 per day, except the team leader who earns a unique amount.

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?
1. Connect mySQL database by using Python. 2. Create database and tables as given below by using Python. (a) BANK database (b) CUSTOMER: customer_id integer, name varchar, lastname varchar, registration_date date, score integer (c) BRANCH: branch_id integer, branch name varchar, cash_hold float, foundation date date, liability float (d) LOAN: loan_id integer, customer_id integer, branch_id integer, amount float Choose primary and foreign keys depending on the base design. 3. Create arrays of at least 5 different records. Use these arrays to populate each table in the database.
We would like to develop a database that captures the following requirements. A University student can enrol in a course and at least in one major. In fact, a student can enrol in many majors within that course. During the semesters, a student can enrol in units. We want to capture in which year and in which semester a student enrolled in each unit. We have two semesters: Semester 1 and Semester 2. A unit has a code, a title and the number of credit points. We would like also to record the student’s GPA. A course has a code and a name. A major has a code and a name. Also, a major belongs to a course. A unit can be part of either a course or a major. A unit can also be shared across different courses and different majors. Important to note: Provide your design in a textual form, i.e. Entity(Attribute1, Attribute2, Attribute3, …). Make sure that the primary keys of each entity are underlined (Attribute1 in the example above) and foreign keys are indictated in bold (Attribute3 in…

Answer the following prompts 1The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team. 2The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENANCE_TYPE_ID…
Read the scenario carefully You have to propose and optimal database design in RDBMS for a super store. In which clients came and can purchase products according to their likes and dislikes. Super store have same products of different companies. In the end client received a receipt of their purchase from counter he/she go for bill. Database also save records of stock according to FIFO system.Your required to define1) Entities and their attributes2) Attributes Types 3) Each Attribute Required space.4) Define keys of each entity 5) Defile relationship between the entities.
