National bodies that are members of ISO or IEC participate in the development of In
15、ternational Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liai
16、son with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part
17、1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the element

23、SO/IEC 19763-12:2015(E)IntroductionThere is an increasing demand for systems to interoperate by exchanging data. For these data exchanges to be meaningful, it is essential that the business information requirements that are met by the data stored in these systems are understood so that suitable data
24、 exchange mechanisms can be developed.Business information requirements, including the semantic meaning of the information, are often represented by information models before the databases that are an integral part of the systems are designed. These models are often called logical models. The subseq
25、uent design of the database structure can also be considered to be another form of information model.Where there is an overlap of the universe of discourse of two systems, the information models for these two systems can be registered using the facilities specified by this part of ISO/IEC 19763. The
26、 mappings between these two models can then be registered using the facilities specified by ISO/IEC 19763-10. An interface between the two systems can then be designed, enabling the two systems to interoperate by exchanging information. ISO/IEC 2015 All rights reserved vBS ISO/IEC 19763-12:2015BS IS
27、O/IEC 19763-12:2015Information technology Metamodel framework for interoperability (MFI) Part 12: Metamodel for information model registration1 ScopeThe primary purpose of the multipart standard ISO/IEC 19763 is to specify a metamodel framework for interoperability. This part of ISO/IEC 19763 specif
28、ies a metamodel for registering information models. This metamodel was developed taking into account two distinct types of information models such as those that are used to document the information requirements of a particular area of interest, and those that represent the structure of a database wh
29、ich are often expressed using a Database Definition Language (DDL).Information models that represent information requirements can be developed using a number of different common diagramming techniques and notations. The metamodel specified in this part of ISO/IEC 19763 was developed to cover the reg
30、istration of models expressed using the following techniques and notations: Express-G, an ISO standard entity-relationship modelling notation, as described in Reference 8; IDEF1X, a US Federal standard entity-relationship modelling notation, as described in References 6 and 12; the entity-relationsh
31、ip modelling notation first developed by Harry Ellis and Richard Barker and later adopted by Oracle for its CASE*Method and by the UKs CCTA for SSADM (Structured Systems Analysis and Design Method), as described in Reference 2; the UML Class Diagram notation, as described in References 13 and 14; th
32、e original entity-relationship modelling notation proposed by Peter Chen, as described in Reference 4; the Information Engineering entity-relationship modelling notation, as described in Reference 11.It is understood that these selected techniques represent all of the essential features of all infor
33、mation modelling techniques used to represent information requirements.The registration of information models that represent the structure of a database is limited in the metamodel specified in this part of ISO/IEC 19763 to those database structures that conform to the Core SQL specification. Core S
34、QL is the set of features defined in the conformance requirements specified in ISO/IEC 9075-2 and ISO/IEC 9075-11.The registration of information models that are expressed using notations such as Object Role Modeling (ORM) and “Natural language Information Analysis Method” (NIAM), collectively known
35、 as fact-based models, is out of scope for this part of ISO/IEC 19763.INTERNATIONAL STANDARD ISO/IEC 19763-12:2015(E) ISO/IEC 2015 All rights reserved 1BS ISO/IEC 19763-12:2015ISO/IEC 19763-12:2015(E)2 Conformance2.1 GeneralAn implementation claiming conformance with this part of ISO/IEC 19763 shall
36、 support the metamodel specified in Clause 5 depending on the degree of conformance as described below.2.2 Degree of conformance2.2.1 GeneralThe distinction between “strictly conforming” and “conforming” implementations is necessary to address the simultaneous needs for interoperability and extensio
37、ns. This part of ISO/IEC 19763 describes specifications that promote interoperability. Extensions are motivated by the needs of the users, vendors, institutions, and industries, but are not specified by this part of ISO/IEC 19763.A strictly conforming implementation could be limited in usefulness, b
38、ut is maximally interoperable with respect to this part of ISO/IEC 19763. A conforming implementation can be more useful, but could be less interoperable with respect to this part of ISO/IEC 19763.2.2.2 Strictly conforming implementationA strictly conforming implementationa) shall support the metamo
39、del specified in Clause 5, andb) shall not use, test, access, or probe for any extension features nor extensions to the metamodel specified in Clause 5.2.2.3 Conforming implementationA conforming implementationa) shall support the metamodel specified in Clause 5, andb) as permitted by the implementa
40、tion, can use, test, access, or probe for any extension features or extensions to the metamodel specified in Clause 5.NOTE 1 All strictly conforming implementations are also conforming implementations.NOTE 2 The use of extensions to the metamodel could cause undefined behaviour.2.3 Implementation Co
41、nformance Statement (ICS)An implementation claiming conformance with this part of ISO/IEC 19763 shall include an Implementation Conformance Statement statinga) whether it is a strictly conforming implementation (2.2.2) or a conforming implementation (2.2.3), andb) what extensions, if any, are suppor
