Abstract
A method for describing software architecture utilizes a service concept to provide a map of the software system's features from top-level functionalities to actual code through all intermediate abstractions. The services are defined as logical and physical services. Physical services are bound to a given level of abstraction by the actual implementation, whereas logical services can be hierarchically divided into smaller logical services. A suitable abstraction level can be used for the logical services so that the best match between physical and logical services can be achieved. Linking physical services to logical services is done so that the set of physical services that implement a set of logical services can be found in a top-down fashion. Also the set of logical services that is implemented by a set of physical services can be found in the bottom-up fashion. The logical service structure can be used as a reference software architecture.
