Describing Service and Request Points
In a service oriented architecture, communications are based on:
• interactions
An interaction represents a contract established in a specific context between autonomous entities that are internal or external to an enterprise. These entities can be enterprise org-units, applications, activities or processes, as well as external org-units. The content of this contract is described by an exchange contract.
• access points: service points and request points.
A request point is a point of exchange by which an agent requests a service from potential suppliers.
A service point is a point of exchange by which an agent offers a service to potential customers.
HOPEX System Oriented IT Architectureenables management of these components and consistency checking of specified information.
