Abstract: The present invention provides a means for an enterprise, such as a health care facility, to receive messages from any one of a plurality of disparate, ancillary vendor applications, convert the vendor information to an enterprise usable form and then store the enterprise information on an enterprise database. The enterprise keeps vendor specific rules for converting each vendor's information to enterprise information. Additionally, relational enterprise rules are applied to the enterprise data stored in a enterprise database, so as disparate vendor information is converted to enterprise data, the relationships between that converted enterprise data are checked with the enterprise data stored in the enterprise database. Enterprise data can also be directly entered into the enterprise database from enterprise system clients, the relationships between that enterprise data are also checked with the enterprise data stored in the enterprise database.
