ISO/IEC 15414:2002(E) ISO/IEC 2002 All rights reserved vIntroduction The rapid growth of distributed processing has led to the adoption of the Reference Model of Open Distributed Processing (RM-ODP). This Refere

20、nce Model provides a co-ordinating framework for the standardization of open distributed processing (ODP). It creates an architecture within which support of distribution, interworking, and portability can be integrated. This architecture provides a framework for the specification of ODP systems. Th

21、e Reference Model of Open Distributed Processing is based on precise concepts derived from current distributed processing developments and, as far as possible, on the use of formal description techniques for specification of the architecture. This Recommendation | International Standard refines and

22、extends the definition of how ODP systems are specified from the enterprise viewpoint, and is intended for the development or use of enterprise specifications of ODP systems. 0.1 RM-ODP The RM-ODP consists of: Part 1: ITU-T Rec. X.901 | ISO/IEC 10746-1: Overview: which contains a motivational overvi

23、ew of ODP, giving scoping, justification and explanation of key concepts, and an outline of the ODP architecture. It contains explanatory material on how the RM-ODP is to be interpreted and applied by its users, who may include standards writers and architects of ODP systems. It also contains a cate

24、gorization of required areas of standardization expressed in terms of the reference points for conformance identified in ITU-T Rec. X.903 | ISO/IEC 10746-3. This part is not normative. Part 2: ITU-T Rec. X.902 | ISO/IEC 10746-2: Foundations: which contains the definition of the concepts and analytic

25、al framework for normalized description of (arbitrary) distributed processing systems. It introduces the principles of conformance to ODP standards and the way in which they are applied. This is only to a level of detail sufficient to support ITU-T Rec. X.903 | ISO/IEC 10746-3 and to establish requi

26、rements for new specification techniques. This part is normative. Part 3: ITU-T Rec. X.903 | ISO/IEC 10746-3: Architecture: which contains the specification of the required characteristics that qualify distributed processing as open. These are the constraints to which ODP standards must conform. It

27、uses the descriptive techniques from ITU-T Rec. X.902 | ISO/IEC 10746-2. This part is normative. Part 4: ITU-T Rec. X.904 | ISO/IEC 10746-4: Architectural semantics: which contains a formalization of the ODP modelling concepts defined in ITU-T Rec. X.902 | ISO/IEC 10746-2 clauses 8 and 9. The formal

28、ization is achieved by interpreting each concept in terms of the constructs of one or more of the different standardized formal description techniques. This part is normative. ITU-T Rec. X.911 | ISO/IEC 15414: Enterprise language: this Recommendation | International Standard. 0.2 This Recommendation

29、 | International Standard Part 3 of the Reference Model, ITU-T Rec. X.903 | ISO/IEC 10746-3, defines a framework for the specification of ODP systems comprising: 1) five viewpoints, called enterprise, information, computational, engineering and technology, which provide a basis for the specification

30、 of ODP systems; 2) a viewpoint language for each viewpoint, defining concepts and rules for specifying ODP systems from the corresponding viewpoint. The purpose of this Recommendation | International Standard is to: Refine and extend the enterprise language defined in ITU-T Rec. X.903 |ISO/IEC 1074

31、6-3 to enable full enterprise viewpoint specification of an ODP system; Explain the correspondences of an enterprise viewpoint specification of an ODP system to other viewpoint specifications of that system; and Ensure that the enterprise language when used together with the other viewpoint language

32、s is suitable for the specification of a concrete application architecture to fill a specific business need. This Recommendation | International Standard uses concepts taken from ITU-T Recommendations X.902 and X.903 | ISO/IEC 10746-2 and 10746-3 and structuring rules taken from clause 5 of ITU-T Re

33、c. X.903 | ISO/IEC 10746-3; it introduces refinements of those concepts, additional viewpoint-specific concepts, and prescriptive structuring rules for enterprise viewpoint specifications. The additional viewpoint-specific concepts are defined using concepts from ITU-T Recommendations X.902 and X.90

34、3 | ISO/IEC 10746-2 and 10746-3. ISO/IEC 15414:2002(E) vi ISO/IEC 2002 All rights reserved0.3 Overview and motivation The purpose of this Recommendation | International Standard is to provide a common language (a set of terms and structuring rules) to be used in the preparation of an enterprise spec

35、ification capturing the purpose, scope and policies for an ODP system. Such an enterprise specification forms part of the specification of an ODP system in terms of the set of viewpoints defined by ITU-T Rec. X.903 | ISO/IEC 10746-3. The primary audience for this Recommendation | International Stand

36、ard consists of those who prepare and use such specifications. An enterprise specification is part of an ODP system specification. It can describe any or all of: an existing system; an anticipated future structure or behaviour of that existing system; a system to be created within some environment.

37、The motivation for a standard enterprise language is to support standardized techniques for specification in order to improve communication and help create specifications that are consistent overall. The enterprise language provides the terms and structuring rules to specify the purpose, scope and p

38、olicies for an ODP system in a manner that is meaningful for the stakeholders for that system, including the owners, the users, the developers and the maintainers. An enterprise specification describes the structure and behaviour of the system within its environment. It explicitly includes those asp

39、ects of the environment that influence the behaviour of the ODP system environmental constraints are captured as well as usage and management rules. Policies about potential changes in the system that may rule its future evolution may also be included. Such an environment can be a technical environm

40、ent (e.g. the software and hardware environment of a service component) or a social or business organization (e.g. a group of co-operating companies, a particular service inside a company). When preparing a specification, there are many approaches that are used for understanding, reaching agreement

41、about, and specifying systems in the context of the organizations of which they form a part. Many of these approaches fall into the categories often referred to as analysis or requirements specification. They can provide useful insights into both the organization under consideration and the requirem

42、ents for systems to support it, but they often lack the rigour, consistency and completeness needed for thorough specification. It is a key objective of this Recommendation | International Standard to provide a way of relating the commonly used concepts and underlying principles of such approaches t

43、o the modelling framework of the RM-ODP. An important objective of an enterprise specification is to support an agreement (for example, as part of the contract for the supply of a system) between the potential owners and users of an ODP system and the provider of that system. Both parties should be

44、able to write, read and discuss such a specification, the owners and users to be sure of the expected structure and behaviour of the system that they will get, and the provider to be clear about the structure and behaviour of the system being provided. Enterprise specifications can also be used at o

45、ther phases of the system life-cycle. The specification can, for example, be used at system run-time to control agreements between the system and its users, to establish new agreements according to the same contract structure and to establish federations. Finally, in the context of the current trend

46、 to integrate existing systems into global networks, where the functionality of interest spans multiple organizations, the enterprise language provides means to specify the joint agreement regarding the structure and behaviour of the ODP systems within and between these organizations. The concepts a

47、nd structuring rules this Recommendation | International Standard provides may be used for development of software engineering methodologies and tools exploiting ODP viewpoint languages, and for development of textual or graphical notations for the ODP enterprise language itself. For these purposes,

48、 this Recommendation | International Standard provides rules for the information content of an enterprise specification and the grouping of that information. Further requirements on the relationships between enterprise language concepts and their correspondences to concepts in other viewpoints are s

49、pecific to the methodologies, tools or notations to be developed. ISO/IEC 15414:2002 (E) ITU-T Rec.
