DATA FLOW DIAGRAM (DFD)

I have this 0-level data flow diagram for the new system for my project. My 0-level DFD should include at least four processes and one data store and should encompass the entire system. I want the DFD should be properly labeled with arrows, process boxes, and data boxes. I'm providing sample of what I want :)

Processes described

i) Customer and Lesson Management - This process controls how consumers are enrolled in various classes, whether they are group or private, and it keeps track of their data in a data repository. Additionally, it oversees the waitlist and distributes emails to clients who were accepted off the waitlist for a program.

ii) Manage Lessons and Instructors - This process organizes the timing of lessons for various periods, builds educator class lists, and keeps track of the credentials and availability of instructors.

iii) Billing and Payment Management - Based on the client's registration in lessons, this procedure creates invoices for them and manages payment processing. Additionally, rebates are given to clients who bring their vehicles in for service.

iv) Vehicle Management - This procedure controls when FAC vehicles are available for the high school to use and makes sure they are not leased out or undergoing repair during the desired time period.

Explanation:

The primary operations and data movements in the new system for the FAC driver instruction program are depicted in the Level 0 data flow diagram (DFD). The system is represented in the diagram by four operations and one data repository.

The illustration displays the following four processes:

Manage Lessons: This procedure is in charge of handling the lessons that the software provides. It involves making the lesson master document, scheduling lessons, establishing waitlists, and enrolling students in courses. The procedure changes the "Instructors and Lessons" and "Student Records" data stores while reading data from the "Instructors and Lessons" data store.

Manage Private classes: This procedure is in charge of handling private classes that community members have asked for. It entails calling instructors to inquire about their availability and tracking the dates that individual classes are scheduled and fees are made. The procedure changes the "Instructors and Lessons" and "Student Records" data stores while reading data from the "Instructors and Lessons" data store.

Manage teachers: This procedure is in charge of overseeing the teachers that the program has recruited. It involves keeping note of the teachers' availability, willingness, and ability to teach each session, as well as their certification to teach which courses. The procedure gets information from the "Instructors and Lessons" data store and changes that database.

Manage Billing: This procedure is accountable for handling the billing process for the application. It involves producing invoices for participants at the conclusion of each session, discounts for repeat clients, and invoices for families with numerous students. The procedure gets data from the data repository called "Student Records" and changes it.

Information about the teachers employed by the program, the classes provided, and the accessibility of instructors and classes is kept in the "Instructors and Lessons" data repository. The "Student Records" data repository houses details on the program members, including their instructions and payment information.

The primary operations and data movements within the new system for the FAC's driver's ed instruction program are depicted in the 0-level data flow diagram (DFD). The system as a whole is represented by the diagram's four operations and one data repository.

The 0-level DFD features four operations, which are as follows:

1) Driver's ed session reservations and billing are handled by this procedure, which also invoices community members for the lessons. It gets information from the Reservation Request procedure about class reservations and student data, and it creates bills for each student based on their involvement in the lesson.

2) The scheduling of instructors for driver's ed courses is handled by this procedure. It gets data from the Master Schedule procedure regarding teacher availability and lesson plans, and it allocates instructors to particular courses in accordance with their certification and availability.

3) Booking for Private classes: This step deals with reserving private classes with particular teachers. It plans private lessons in accordance with the information it gets about community members' inquiries for private lessons and the availability of the instructors from the Instructor Scheduling procedure.

4) Vehicle Lending: This procedure deals with the lending of automobiles to the neighborhood high school for driver education classes. It learns about vehicle availability through the Master Schedule procedure and grants high school requests for vehicle rental.

The Master Schedule, which contains details about class plans, teacher availabilities, and car availabilities, is the data store represented in the 0-level DFD. The Reservations and Billing process, the Instructor Scheduling process, and the Vehicle Borrowing process are just a few of the processes that contribute to the Master Schedule.
