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 have a specific race ID and a race name.

They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles. Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.arrow_forward
- The administrators of Tiny College are so pleased with your design and implementation of their student registration and tracking system that they want you to expand the design to include the database for their motor vehicle pool. A brief description of operations follows: Faculty members may use the vehicles owned by Tiny College for officially sanctioned travel. For example, the vehicles may be used by faculty members to travel to off-campus learning centers, to travel to locations at which research papers are presented, to transport students to officially sanctioned locations, and to travel for public service purposes. The vehicles used for such purposes are managed by Tiny College’s Travel Far But Slowly (TFBS) Center. Using reservation forms, each department can reserve vehicles for its faculty, who are responsible for filling out the appropriate trip completion form at the end of a trip. The reservation form includes the expected departure date, vehicle type required,…arrow_forwardThe administrators of Tiny College are so pleased with your design and implementation of their student registration and tracking system that they want you to expand the design to include the database for their motor vehicle pool.

- 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.arrow_forwardThe entity relationship diagram below models the components of a database belonging to the South African Film Writers' Association.
