This page contains System analysis design of hospital management system. The purpose of design phase is to plan a solution for problem specified by the requirements. System design aims to identify the modules that should be in the system, the specification of those modules and how they interact with each other to produce the result. The goal of the design process is to produce a model or representation of a system can be used later to build that system. The produced model is called design of the system.
Applicable Document
As the project is user friendly, it can be applied to large database with more information. This software can be used by hospital management to make the work simple. They can get information quickly as possible. It can handle large volume of data and present the report whenever required. In this project, we use SRS as the applicable document.
Functional Component and Assumptions
- Administration module: Administrator can view all the details of the hospital record.
- Inpatient module: This module is used to store details of patients who are admitted.
- Outpatient module: The outpatient module contains details of the patient who are came for check_ups.
- Lab module: Lab module is used to generate laboratory reports.
- Billing module: Billing module is used to calculate the bill of the patient.
Context Flow Diagram:-
A context flow diagram is a 0th level DFD.It only contains one process node that generalizes the functions of the entire system in relationship to external entities.
