Background:

Properprop is an Australian real estate company involved in a variety of real estate investments and activities. This is a company with a large number of customers who need a variety of different services. Properprop has a web site that shows individual property information. Customers can search the company web site for properties based on suburb and price. If a customer cant find any matches, they are asked to contact the company via phone or online messaging to ask the company to search on their behalf. A Properprop agent then searches the other real estate databases that they have access to for potential matches. If the agent finds any matches, they then contact the real estate companies responsible for those properties and update the customer on their findings If a property is found that the customer wants to inspect, they can make an appointment with an agent to view the property. After the inspection, if the customer decides to buy or rent the property, the responsible agent will prepare the relevant paperwork. The agent makes a record of the property data and the buyer/tenants information for future use. As demand for their services has grown Properprop has decided to design and implement a webbased information system to assist in the management of their processes. It is envisaged that the information systems will manage the overall operational activities and processes, starting from the management of the property, to the management of real estate agencies, agents, clients, and financial transactions. The system will be required to provide comprehensive reports for analyzing the real estate agencys performance and efficiency to enable management to make better-informed decisions. The system should address as a minimum the following requirements: Assist customers to search for different properties based on: o Property type, i.e.: house, townhouse, unit, apartment, and land o Price range o Suburb, address, postcode o Min and max bedrooms o Min and max bathrooms o Car spaces o Availability date Assist customers to register their information and preferences Inform registered prospective customers by email whenever a property that matches their preferences becomes available Maintain all properties in the database, and keep seller and owner information You are asked to analyze and design an information system for the above scenario using objectoriented methodology. You can make any reasonable assumptions about the case scenario.
