Summary
Real estate multiple listing service systems help agents share property information. Students learn how to model and design a system to handle real estate listings, agents and offices.
System Requirements
A real estate multiple listing service system must respond to various events. Students create an event table for these events and their use cases. The events include submitting new listings, requesting listing information, and producing multiple listing books.
Diagrams for the System
Students develop use case diagrams, system sequence diagrams, and activity diagrams. These diagrams show how users interact with the system and how the system processes requests. A use case diagram is drawn for the system.
Data Storage Requirements
An entity relationship diagram represents the data the system needs to store. Students decide which data entities and attributes are necessary. The diagram includes information about real estate offices, agents, and listings.
Domain Class Diagram
Students convert the entity relationship diagram into a domain class diagram. They create subclasses for different types of listings, such as single-family houses and commercial properties. The diagram shows the relationships between the classes.
