21、 This document, together with EN 12967-1 and EN 12967-3, supersedes ENV 12967-1:1998. This document represents part two of a three-part European standard, which is a major revision of ENV 12967-1, produced under a mandate given to CEN by the European Commission and the European Free Trade Associatio
22、n. This multi-part standard under the general heading: Health informatics Service architecture consists of the following parts: Part 1: Enterprise viewpoint Part 2: Information viewpoint Part 3: Computational viewpoint According to the CEN/CENELEC Internal Regulations, the national standards organiz

25、 multi-part standard that provides guidance for the description, planning and development of new systems as well as for the integration of existing information systems, both within one enterprise and across different healthcare organisations through an architecture integrating the common data and bu
26、siness logic into a specific architectural layer (i.e. the middleware), distinct from individual applications and accessible throughout the whole information system through services, as shown in Figure 1. Figure 1 The overall architecture specified by this standard is formalized according to the ISO
27、/IEC 10746 (all parts) criteria and is therefore structured through the three viewpoints: Enterprise Viewpoint that specifies a set of fundamental common requirements at enterprise level with respect to the Organisational purposes, scopes and policies that must be supported by the information and fu
28、nctionalities of the middleware. It also provides guidance on how one individual enterprise (e.g. a regional healthcare authority, a large hospital or any other where this model is applicable) may specify and document additional specific business requirements, with a view of achieving a complete spe
29、cification, adequate for the characteristics of that enterprise. The Enterprise Viewpoint is specified in Part 1 of this multi-part standard; document EN 12967-1. Information Viewpoint that specifies the fundamental semantics of the information model to be implemented by the middleware to integrate
30、the common enterprise data and to support the enterprise requirements Formalized in the Enterprise Viewpoint. It also provides guidance on how one individual enterprise may extend the standard model with additional concepts, needed to support local requirements in terms of information to be put in c
31、ommon. The Information Viewpoint is specified in this document EN 12967-2. Computational Viewpoint that specifies the scope and characteristics of the services that must be provided by the middleware for allowing the access to the common data as well as the execution of the business logic supporting
32、 the enterprise processes identified in the Information and Enterprise viewpoints. It also provides guidance on how one individual enterprise may specify additional services, needed to support local specific requirements in terms of business logic to be put in common. The Computational Viewpoint is
33、specified in Part 3 of this multi-part standard; document EN 12967-3. Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 02:34:37 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 12967-2:2007 (E) 6 1 Scope This standard specifies the fundamental characteristics of the
34、 information model to be implemented by a specific architectural layer (i.e. the middleware) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare Organisation, as defined in part
35、1 of this standard “Health Informatics Service Architecture - Part 1: Enterprise viewpoint”. The information model is specified without any explicit or implicit- assumption on the physical technologies, tools or solutions to be adopted for its physical implementation in the various target scenarios.
36、 The specification is nevertheless formal, complete and non-ambiguous enough to allow implementers to derive an efficient design of the system in the specific technological environment that will be selected for the physical implementation. This specification does not aim at representing a fixed, com
37、plete, specification of all possible data that may be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics in terms of overall Organisation and individual information objects- identified as fundamental and common to all healthcare Organisations, and
38、that shall be satisfied by the information model implemented by the middleware. Preserving the consistency with the provisions of this standard, physical implementations shall allow extensions to the standard information model in order to support additional and local requirements. Extensions shall i
39、nclude both the definition of additional attributes in the objects of the standard model, and the implementation of entirely new objects. Also this standard specification shall be extensible over time according to the evolution of the applicable standardisation initiatives. The specification of exte
40、nsions shall be carried out according to the methodology defined in part 1 of this standard EN 12967-1, clause 7, “Methodology for extensions”. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、se Information Components 5 Methodological principles 5.1 Language and notation adopted for the specification of the model (informative) Objective of information viewpoint specification is the description of the information relevant for the enterprise to be handled by the middleware. It shall consis
46、t of a formal information model detailing the semantic and syntactic aspects of all data to be managed. The specification is based on an object model, derived from the enterprise viewpoint by properly structuring and aggregating the information that has been identified as relevant in the specificati
47、on of the business processes, tasks and activities. While the general approach of the ODP standard is used also for the Information Viewpoint part of this standard, the modelling language to be used is UML, which was not available at the time of the first edition of the ODP standard. The information
48、 viewpoint is concerned with information modelling (i.e. the kinds of information handled by the system). It focuses on the semantics of information and information processing in the system. The individual components of a distributed system must share a common understanding of the information they c
49、ommunicate when they interact, or the system will not behave as expected. Some of these items of information are handled, in one way or another, by many of the objects in the system.
