Abstract: A system for governing entry of data into a database commonly accessible by a plurality of entities, each of which has requirements for its data that differ from the requirements of other entities, comprised one or more rules base servers for storing a rules base data structure. The data structure is a collection of documents which are either a rule applicable to an entity or a rules interface which provides a navigation route to an applicable rule. The system includes a rules engine which executes an algorithm that recursively searches the documents in the rules base, evaluating each document until a rule is found, executing the rule, and storing the result returned by the executed rule, until all applicable rules for the entity submitting the set of data are executed.

Abstract: A system for facilitating association of a consumer with a transaction agent includes a database server accessible over a communications network and configured to store data comprising either of a buyer lead pool, and selling agent lead pool. The database server is accessible by an application server having a web application that allows a consumer to indicate whether the consumer is interested in buying a property or in selling property. In the former case, the system sends a message to the listing agency whereupon the listing agent may access, or “claim,” the buyer's data, and allows non-listing agents to claim the data if the listing agent declines. In case the consumer desires to sell property, the system notifies all agents within the relevant geographic area corresponding to the property and allows a consumer to interview candidate agents.
