PWS is a physician's workstation research prototype developed to explore the use of information management tools by physicians in the context of patient care. The original prototype was implemented in a client/server architecture using a broadcast message server. As we expanded the scope of the prototyping activities, we identified the limitations of the broadcast message server in the areas of scalability, security, and interoperability. To address these issues, we reimplemented PWS using the Open Software Foundation's Distributed Computing Environment (DCE). We describe the rationale for using DCE, the migration process, and the benefits achieved. Future work and recommendations are discussed.
PWS是一个医生工作站研究原型，旨在探索医生在患者护理过程中对信息管理工具的使用。最初的原型是在客户端/服务器架构中使用广播消息服务器实现的。随着我们扩大原型活动的范围，我们发现了广播消息服务器在可扩展性、安全性和互操作性方面的局限性。为了解决这些问题，我们使用开放软件基金会的分布式计算环境（DCE）重新实现了PWS。我们描述了使用DCE的基本原理、迁移过程以及所取得的好处。还讨论了未来的工作和建议。
