Abstract: A network (e.g., Internet) based gaming system and one or more casino management systems (CMS) are connected to manage patron data, loyalty programs, and other data. The connection may be implemented as an abstracted integration. As such, the connection mechanism may be used to connect the network based gaming system to a variety of proprietary and other CMS types. The connection mechanism may be synchronous, such as for example via a web service using XML over SOAP, or asynchronous, such as for example using a message sender/listener system such as system-2-system (S2S).
