Performing a functionality
In HOPEX IT Architecture, a service catalog is made up of service catalog item. For example, an information service catalog is made up of several information service catalog items.
*An information service catalog provides a centralized information source for the information services offered by the service provider organization. It contains a customer-oriented view of the information services used, how they are supposed to be used, the processes that they support as well as the expected service quality level. The information service catalog presents the list of functionalities mentioned as well as implementation recommendations.
*An information service catalog item defines which functionality is in the catalog and which application artifacts provide the functionality.
A service catalog item is connected to one or more functionalities.
*A functionality is a capability expected from an equipment item (hardware or software) to ensure the operation of a business function or an organization. If it is a software functionality, it can be provided by an application.
With HOPEX IT Architecture, the implementation of a functionality is represented by a realization.
*A realization describes the relationship between a logical entity and a physical entity that implements it. The physical entity gives the list of logical entities that it implements.
The table below draws up the summary of objects that implement the service catalogs according to their category.
