The development of an innovative clinical decision-support project such as the University of Minnesota's Clinical Workstation initiative mandates the use of modern client-server network architectures. Preexisting conventional laboratory information systems (LIS) cannot be quickly replaced with client-server equivalents because of the cost and relative unavailability of such systems. Thus, embedding strategies that effectively integrate legacy information systems are needed. Our strategy led to the adoption of a multi-layered connection architecture that provides a data feed from our existing LIS to a new network-based relational database management system. By careful design, we maximize the use of open standards in our layered connection structure to provide data, requisition, or event messaging in several formats. Each layer is optimized to provide needed services to existing hospital clients and is well positioned to support future hospital network clients.
开发一个创新的临床决策支持项目，如明尼苏达大学的临床工作站计划，需要使用现代客户端-服务器网络架构。由于此类系统成本高且相对难以获取，现有的传统实验室信息系统（LIS）无法迅速被客户端-服务器等效系统所取代。因此，需要采用能有效整合遗留信息系统的嵌入策略。我们的策略导致采用了一种多层连接架构，该架构将现有LIS中的数据馈送到一个新的基于网络的关系数据库管理系统。通过精心设计，我们在分层连接结构中最大限度地使用开放标准，以提供多种格式的数据、申请或事件消息传递。每一层都经过优化，可为现有医院客户端提供所需服务，并且能够很好地支持未来的医院网络客户端。
