Service Infrastructure
(KM-SI)
Services are entities providing some piece of functionality by well-defined interfaces. In a dynamic service invocation environment, clients retrieve service information from service registries in a form ready for direct service access. These proxies represent the service to the programmatic client. In static invocation, clients need to compile and create proxy stubs to access a service whereas in dynamic invocation these are created in runtime. The major difficulty in engineering such systems is to create service descriptions where each implementation uses the same signatures, and to overcome implementation language dependence. [CD-JRA-2.3.3]


Generic
(domain independent)
Dynamic invocation allows programmatic clients to access remote processes at runtime relying on interface descriptions only. [WSbook]

Dynamic Invocation is the execution of a service whose interface is first known at run time. [CD-IA-1.1.1]
