OEM Grid Control provides an extensible model that depicts the complex hierarchy of composite business services within an enterprise. OEM Grid Control provides an out-of-box model, that is, aggregate service to define, monitor, and manage composite business services. Aggregate services are a special class of services and are defined based on other service types. In the preceding travel portal example, the enterprise-wide travel search business function can be modeled as an aggregate service target, that is, TravelSearchService defined based on HotelSearchService and FlightSearchService. These two service targets that define an aggregate service are called Subservices.
The aggregate service target model in OEM Grid Control is extensible, that is, an aggregate service has all the features of a single service target and could comprise among other service targets, another aggregate service target.
