MicroHousing System in Kuala Lumpur

Big cities are always expensive to live in, but even more so for young people who have to live

independently, whether they are college students, fresh graduates or job seekers.

Proposals to alleviate the housing crisis in major cities have been proposed in the United States

(, Canada


and-a-business/), Hong Kong (



Youths in Kuala Lumpur also face similar problems. Therefore, the Kuala Lumpur City Hall (DBKL)

has proposed a scheme to help youths to rent accommodation at affordable prices



Your job is to create the information system for the MHS (Micro Housing System) for DBKL. Some

analysis and design artifacts have been developed. The use case diagram (Figure 1) shows the main

users of the system and basic functionalities.

The Conceptual Model shown above depicts the relationship that exists between classes in this

assignment. The User class is an abstract class, and is the superclass to the two concrete

subclasses – Applicant and HousingOfficer. For all classes, you may include additional

methods if you wish to do so, for example the toString, and equals methods. Two users are

considered equal if their username are the same.

A MHS object references a collection of Users and a collection of Residences. These two

collections are separate. You will also notice that Residences are linked to the Application class

as well as the Unit class. Class Unit is an inner class of Residence. Both classes, Application

and Unit, are linked together throught the class Allocation.

The following shows the high level use cases for the functionalities stated above.

availability of each unit is set to “available”.
