Architecture for the Validation Testing System Software Testbed Report Series

摘要

The problem of sharing data has many facets. The need for the capability to sharedata across multiple enterprises, different hardware platforms, different data storage paradigms and systems, and a variety of network architectures is growing. The emerging Standard for the Exchange of Product Model Data (STEP), a project of the International Organization for Standardization (ISO), addresses this need by providing information models, called application protocols, which clearly and unambiguously describe data. The validity of these information models is essential for success in sharing data in a highly automated business environment. The document describes an architecture for an integrated software environment to support the validation of STEP application protocols. The architecture provides a basis for software development to support the Validation Testing System (VTS) within the National Product Data Exchange using STEP (PDES) Testbed. (PDES is the U.S. effort in support of the international standard.) The software architecture and the use of object-oriented techniques enables code reusability and system extensibility. The software developed for the VTS can provide the foundations for STEP related systems or software projects requiring general purpose editing tools for structured information.
