Visual C++ Program for the Implementation of Hospital Management System | IT1253 - Software Engineering Laboratory

ABSTRACT:

The aim of our project is to develop a software for implementing “Hospital management system” using VISUAL C++. The development of this particular project is to perform the formalities / operation in HOSPITAL MANAGEMENT SYSTEM. This project deals with the patient details, type of disease, and maintenance in its process. The customers are instructed in an easy way to feel comfortable with the processing.

REQUIREMENTS ANALYSIS:

SOFTWARE REQUIREMENTS:
    Front End   :    ‘C++’ language.
    Back End   :     File Management System (using Dat files)
    Operating system:    Any Operating System (Window or Linux)

HARDWARE REQUIREMENTS:

    Processor     :     3.06 GHZ operating speed.
    Hard Disk    :      80GB Capacity.
    RAM           :       256MB
    Monitor       :       CRT 17’
    Mouse         :       OPTICAL
    Keyboard    :       Alphanumeric keys.
     The specified hardware requirements are the minimum requirements that are needed to implement in the project.

FUNCTIONAL REQUIREMENTS:
    As mentioned in the requirements, the Hospital Management system involves the following function or process
Hospital Management system consists of four modules. They are
    Module 1: Insert Module
    Module 2: Delete Module
    Module 3: Display Module
    Module 4: Exit
Insert Module :
In this module the user enters the detail of the patient.
Delete Module :
In this module the user deletes the detail of the patient.
Display Module :
This module display the detail of the patient.
Exit:
    In this module the user can quit from the project.

NON FUNCTIONAL REQUIREMENTS:

    It is reliable software. Whenever the user wants to retrieve any information from the database, it returns with the correct information. Provided, the information stored is a correct one. The cost of maintenance of the software is very low. The size of the software is less. This means, it is a portable one. If any request is given, the time taken for the response is low. This makes the software more efficient.

CONCLUSION:

             The  project we have done here is “ONLINE SUPERMARKET SYSTEM” using C language.
In this project we have designed a software to implement the customer details that any user can perform
it in a simple and a better way. This way of format helps us to have clear database.
