Computerized Enrollment System Data flow diagram is often used as a preliminary step to create an overview of the Enrollment without going into great detail, which can later be elaborated.it normally consists of overall application dataflow and processes of the Enrollment process. It contains all of the userflow and their entities such all the flow of Students, Courses, Registration, Faculties, Branches, Login, Authentication. All of the below diagrams has been used for the visualization of data processing and structured design of the Enrollment process and working flow.
Zero Level Data flow Diagram(0 Level DFD) of Computerized Enrollment System :
This is the Zero Level DFD of Computerized Enrollment System, where we have eloborated the high level process of Enrollment. It’s a basic overview of the whole Computerized Enrollment System or process being analyzed or modeled. It’s designed to be an at-a-glance view of Branches,Login and Authentication showing the system as a single high-level process, with its relationship to external entities of Students,Courses and Registration. It should be easily understood by a wide audience, including Students,Registration and Branches In zero leve DFD of Computerized Enrollment System, we have described the high level flow of the Enrollment system.High Level Entities and proccess flow of Computerized Enrollment System:
- Managing all the Students
- Managing all the Courses
- Managing all the Registration
- Managing all the Faculties
- Managing all the Branches
- Managing all the Login
- Managing all the Authentication
First Level Data flow Diagram(1st Level DFD) of Computerized Enrollment System :
First Level DFD (1st Level) of Computerized Enrollment System shows how the system is divided into sub-systems (processes), each of which deals with one or more of the data flows to or from an external agent, and which together provide all of the functionality of the Computerized Enrollment System system as a whole. It also identifies internal data stores of Authentication, Login, Branches, Faculties, Registration that must be present in order for the Enrollment system to do its job, and shows the flow of data between the various parts of Students, Registration, Login, Authentication, Branches of the system. DFD Level 1 provides a more detailed breakout of pieces of the 1st level DFD. You will highlight the main functionalities of Enrollment.Main entities and output of First Level DFD (1st Level DFD):
- Processing Students records and generate report of all Students
- Processing Courses records and generate report of all Courses
- Processing Registration records and generate report of all Registration
- Processing Faculties records and generate report of all Faculties
- Processing Branches records and generate report of all Branches
- Processing Login records and generate report of all Login
- Processing Authentication records and generate report of all Authentication
Second Level Data flow Diagram(2nd Level DFD) of Computerized Enrollment System :
DFD Level 2 then goes one step deeper into parts of Level 1 of Enrollment. It may require more functionalities of Enrollment to reach the necessary level of detail about the Enrollment functioning. First Level DFD (1st Level) of Computerized Enrollment System shows how the system is divided into sub-systems (processes). The 2nd Level DFD contains more details of Authentication, Login, Branches, Faculties, Registration, Courses, Students.Low level functionalities of Computerized Enrollment System
- Admin logins to the system and manage all the functionalities of Computerized Enrollment System
- Admin can add, edit, delete and view the records of Students, Registration, Branches, Authentication
- Admin can manage all the details of Courses, Faculties, Login
- Admin can also generate reports of Students, Courses, Registration, Faculties, Branches, Login
- Admin can search the details of Courses, Branches, Login
- Admin can apply different level of filters on report of Students, Faculties, Branches
- Admin can tracks the detailed information of Courses, Registration, Faculties, , Branches
