41、 Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of
42、technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint t

49、tural style in which business and IT systems are designed in terms of services available at an interface and the outcomes of these services. A service (see ISO/IEC 18384-1:2016, 3.20) is a logical representation of a set of activities that has specified outcomes, is self-contained and may be composed of other services but consumers of the service need not be aware of any internal structure. SOA uses services to create and integrate information systems so that they are suitable for a variety
