The standardized service contract is a software design principle [1] applied within the service-orientation design paradigm to guarantee that service contracts [2] within a service inventory [3] (enterprise or domain) adhere to the same set of design standards. [4]
Due to the fallacies of distributed computing, finding an adequate granularity is hard. [2] There is no single simple answer but a number of criteria exist (see below). A primary goal of service modeling and granularity design is to achieve loose coupling and modularity, which are two of the essential SOA principles, [3] and to address other architecturally significant requirements.
Within a SOA, the development of solution logic is driven by the needs of the business and is designed in a manner that focuses on the long-term requirements of the business. As a result, the technology architecture is more aligned with the business needs.
Service-oriented modeling is an SOA framework that identifies the various disciplines that guide SOA practitioners to conceptualize, analyze, design, and architect their service-oriented assets. The Service-oriented modeling framework (SOMF) offers a modeling language and a work structure or "map" depicting the various components that ...
Similar concepts are used for sequences of discretizations. For instance, ideally the solution of a differential equation discretized via a regular grid will converge to the solution of the continuous equation as the grid spacing goes to zero, and if so the asymptotic rate and order of that convergence are important properties of the gridding ...
Within a service composition, service may be required to keep track of data that is specific to the running of a particular service activity, which is usually linked with the coordination of messages, e.g. workflows, and the associated rules that govern how the rules are to be interpreted.
In numerical analysis, fixed-point iteration is a method of computing fixed points of a function.. More specifically, given a function defined on the real numbers with real values and given a point in the domain of , the fixed-point iteration is + = (), =,,, … which gives rise to the sequence,,, … of iterated function applications , (), (()), … which is hoped to converge to a point .
The existing models and meta models (e.g. TOGAF) for describing system architectures turned out to be insufficient to describe SOA in a precise and standardized way. The UML itself seems to be too general for the purpose of describing SOA and needed clarification and standardization of even basic terms like provider, consumer, etc.
