This document describes the development of a hospital management system using a database. It includes tables for patients, doctors, wards, specializations, and diseases. It shows the structure of each table with fields and constraints. It also provides examples of SQL queries for insert, update, delete, and join operations on the tables. The goal is to develop a software system to more easily manage patient records and data within a hospital using an electronic database rather than a manual paper-based system.

2.  As we know that the manual system is too much difficult
to handle the record in our daily life. In the present era
of globalization and advanced technology efficient
record keeping cannot be overemphasized. Imagine the
scenario when the manual processes and manual
modes of instruction get replaced with electronic
systems. One of such replacement can be done in the
area of patient’s database management system within a
hospital. Developing patient database management
system software would benefit the hospital management
who can have effortless access to the data securely and
more easilsy.Hospitals are not excluded in record
keeping. The records kept include patient data, which
help to maintain patient’s medical records.
