An implementation foundation for a telecommunication service provider provides an efficient, robust, and reliable cornerstone for any new telecommunication service provider architecture. The implementation foundation includes a universally applicable data model that encodes the fundamental entities of interest to telecommunications service providers. The data model is free of constraints on any particular technology, and provides a reusable foundation for implementing new telecommunication service providers. The data model is composed of business entities that technically support business processes for a telecommunication service provider. As a result, new telecommunication service providers may be implemented in a rapid manner on a proven foundation, without complex and unwieldy customized technologies that rely on immensely complicated point-to-point message connections.
