In-Depth Information
Service granularity : This is a design consideration to provide optimal
scope and the appropriate granular level of the business functional-
ity in a service operation.
Service normalization : Services are decomposed and/or consolidated
to a level of normal form to minimize redundancy. In some cases,
services are denormalized for specific purposes, such as perfor-
mance optimization, access, and aggregation.
Service optimization : All else being equal, high-quality services are
generally preferable to low-quality ones.
Service relevance : Functionality is presented at a granularity recog-
nized by the user as a meaningful service.
Service encapsulation : Many services are consolidated for use under
the SOA. Such services often were not planned to be under SOA.
Service location transparency : This refers to the ability of a service
consumer to invoke a service regardless of its actual location in the
network. This also recognizes the discoverability property (one of
the core principle of SOA) and the right of a consumer to access the
service. Often, the idea of service virtualization also relates to loca-
tion transparency. This is where the consumer simply calls a logical
service while a suitable SOA-enabling runtime infrastructure com-
ponent, commonly a service bus, maps this logical service call to a
physical service.

architecture capabilities of Oracle Fusion Architecture. Oracle Fusion is
