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