GB/T 18714.3-2003

This standard defines the architectural framework for open distributed processing (ODP) systems, specifying viewpoints, concepts, and rules for structuring distributed applications. It is applied in the design and development of large-scale, heterogeneous IT systems, such as telecommunications networks, enterprise middleware, and cloud computing platforms, to ensure interoperability and portability across different vendor environments. The standard serves as a reference for engineers and procurement professionals when specifying system architecture requirements for complex distributed computing projects.
