This document presents a database system for managing rooms for rent, commonly known as student messes or bachelors' messes. The database will contain information about rooms like monthly rent, facilities, and distance from universities. Students will be able to search rooms based on these criteria. Room owners can add their rooms to the database to find tenants. The proposed system uses ER diagrams and normalization to model the data. Sample queries demonstrate searching for rooms within a rent price range or of a certain size, and finding landlord and tenant details. The goal is to make room hunting easier for students in new areas.

Introduction
In this project, I am willing to make a system for “Room for Rent(Student’s
mess)” management based on DataBase Management System.
Basically, the main goal here is to make a database that contains datasets on
different rooms for rent for students and bachelors(commonly known as
Student’s mess/ batchelor’s mess), with their monthly rates, living facilities and
distance from the university(or workplace). The users can view their renting
options with respect to all the aforementioned parameters. The room owners
will have the opportunity to put their rooms up for rent by providing necessary
informations about their rooms, and when a new record is added or
deleted(once a room gets rented) the database will be updated promptly.

Motivation
In our country, a lot of students after completing their higher secondary
, has to leave home to study in universities, often in new and unknown
areas. Also because of the high number of students, not all the students
can get to stay in university’s dormitory. In a lot of universities, the
students don’t get seats in the university’s dormitory for a long period
of time, ranging from a few months to one or two years. The students
then seek to rent rooms, commonly known as ‘mess’ nearby the
university and live there. But often as they are in completely new
places and they don’t really know the area well, they fail to find perfect
rooms for them. This database will help the students with all the data
they need to choose the perfect ‘mess’ to rent.

 To make a database that will present the users with a wide variety of rooms for
rent, and the users will be able to sort through them with respect to rent, facilities
and workplace distance.
 Also enabling the room owners to put their rooms up for rent in the database
which will get him/her a higher customer base.
 An overall view of the market will be available to renters to choose.
 To learn and implement MySQL while working on the project.

Conclusion
The purpose of this database is to make room
hunting easier for the massive student population
who most often find it difficult to find proper living
condition, as they are often in a completely new
place. Also it will be beneficial for the room owners
as they will be able to reach a larger customer base.
Admin will update everytime a room gets vacated or
put up for rent.
