On-Demand Online Real Estate Information System

Internet is helping change the structure of the residential real estate industry by offering new services in the system aiming to enhance the facilities provided to the user. This would enhance the demand chain management. The first purpose of this paper is to illustrate these changes by specifying the functional components of the demand chain management system for online real estate. The author uses a formal specification language to model the interaction between the online real estate management system, the new entities and the other actors. The proposed online real estate management system includes advanced modules that can be bundled together, creating differentiation and enhancing the value chain. The second objective is to propose a simplified implementation architecture for an integrated demand and supply chain management system for online real estate services. The author chose an open source Customer Relationship Management system as a platform to manage some of the online real estate modules. Other value-added modules are integrated from third-party providers using their open interfaces.
