A wireless system and method which provides data access and retrieval from a Multiple Listing Service or other data store. The system provides access to real estate data and/or information by real estate professionals, field technicians or remote users without the necessity of being confined to an office or behind a desk to do the same. The system uses a web-based or wireless application protocol enabled device such as a cellular phone or personal digital assistant (PDA) within a data store and server network which significantly reduces data access and retrieval time which are primary cost drivers in the wireless industry.
