Hi,
The above diagram clearly depicts the Hospital Management System, in other words its ER-Diagram for Hospital Management.
SYSTEM DESIGN
1. Introduction
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.
2. 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.
3. Functional Decomposition
Functional decomposition refers broadly to the process of resolving a functional relationship into its constituent. Parts in such a way that the original function can be reconstructed from those parts by function composition. In general, this process of decomposition is undertaken either for the purpose of gaining insight into the identity of constituent components (which may reflect individual physical processes of interest, for example) or for
the purpose of obtaining a compressed representation of the global function, a task which is feasible only when the constituent processes possess a certain level of modularity.
4. Functional Component and Assumptions
4.1. Administration module:-
Administrator can view all the details of the hospital record.
4.2. Inpatient module:-
This module is used to store details of patients who are admitted.
4.3. Outpatient module:-
The outpatient module contains details of the patient who are came for check_ups.
4.4. Lab module:-
Lab module is used to generate laboratory reports.
4.5. Billing module:-
Billing module is used to calculate the bill of the patient.
5. Description of the Program
5.1. 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.

5.2. Data Flow Diagram
A Data flow diagram is a graph showing the flow of data values from their sources in objects through processes that transform them to their destination in other objects.
A DFD also known as “bubble chart”, has the purpose of clarifying the system requirements and identifying major transformation that will become programs in system design.So, it is the starting point of the design phase that functionally decomposes the requirements specifications down to the lowest level of detail.A DFD consists of a series of bubbles joined by lines.
DFD use a number of symbols to represent systems. Most Data flow modeling method use 4 kinds of symbols to represent four kinds of system components:-
Symbols
Description
Process
A process shows a transformation or manipulation of data flows within the system.
External entity
External entities are outside the system, but they either supply input data into the system or use system output.
Data flows
A data flow shows flow of information from source to destination. A data flow is represented by a line, with arrowhead showing the direction of flow.
Data base
Database is a huge collection of data. It is used for storage purpose.

5.3. Description of Component
5.3.1. Administration module:-
Input: - User Name, Password
Process Definition: - Login to the system
Output:-If login is successful then administrator can view and update the records.
5.3.2. Inpatient module:-
Input: - Inpatient detail
Process Definition: - Information about the treatment given to the patients who are admitted.
Output: - Information about the patient.
Interface with other module: - The inpatient details are necessary for lab reports and billing.
5.3.3. Outpatient module:-
Input: - Outpatient detail
Process Definition: - This module has the information about the treatment given to the patient who are came to check up.
Output: - Information about the patient.
Interface with other module: - The outpatient details are necessary for lab reports and billing.
5.3.4. Lab module:-
Input: - Patient ID, Category
Process Definition:-Laboratory reports of the patient.
Output: - Lab report and charge.
Interface with other module: - This module requires information from inpatient and outpatient modules.
5.3.5. Billing module:-
Input: - Patient ID
Process Definition:-Calculates bill and deduct amount if any card facility is available.
Output: - Bill.
Interface with other module: - Billing module requires information from inpatient and outpatient modules.
