data granularity
|
The quantity of data exchanged by a specific service capability determines the level of its data granularity. For example, a Get capability that retrieves and returns an entire business document will have a coarser level of data granularity than a GetHeader capability that only returns a subset of the business document data.
Note that the data granularity of a capability does not always correspond to the capability granularity. A capability may be fine-grained because it performs a simply query. However, its data granularity may be coarse-grained because the quantity of information it retrieves is large.
Data granularity represents one of four types of design granularity, the other three being service, capability, and constraint granularity. Each of these granularity types is affected differently by the application of service-orientation design principles.
