Software components-a scalable solution to platform independent software development for commercial applications

摘要

The Universal Component System (UCS), a platform-independent application development system targeted for large-scale, commercial applications, is discussed. UCS runs on several platforms, including Microsoft Windows, Macintosh, Unix/Motif, and Open-look. UCS addresses three major aspects of application portability: user interface, system services, and connectivity. UCS uniquely addresses traditional functionality-performance design tradeoffs by providing an architecture scalable to application developers' needs. The authors describe the design philosophy of UCS, and contrast it with other approaches. They highlight several unique aspects of the system, illustrating how their goals influenced the design of specific UCS components.
