臨床路徑診治系統不同于一般的管理信息系統，在系統的實時性、可靠性、規范性
等方面要求更高，許多傳統的分析及設計工具已難以滿足新要求，而UML 是一種易于表達、 功能強大的面向對象標準建模語言，它將逐漸成為面向對象軟件系統分析設計的必備工具。文章以Rational Rose 作為UML 建模的工具，主要通過用例圖、活動圖和時序圖對“心腦血管疾病的臨床路徑診治系統”進行描述。由于系統采用了UML 建模技術，從而使得軟件結構更加合理，提高了軟件開發的效率。

Analysis of modeling clinical-pathways diagnoses system based on UML Tang Wei，Li Xi，Wu Guobing （Information Science school, Nanjing Audit university, Nanjing 210029）
Abstract：Clinical-pathways diagnoses system is different from common MIS, which has higher demand in real-time character, reliability and normative character, so many traditional analysis and design tools are difficult to satisfy new requirements. UML, as an expressive and powerful standard object-oriented modeling language, will become a necessary tool to analyze and design object-oriented software systems. With Rational Rose software as a UML modeling tool, a clinical-pathways diagnoses system about cardio-cerebral-vascular disease is described by using use case diagram, activity diagram and sequence diagram. Because of adopting UML modeling technology, the system has more reasonable architecture, and development efficiency has been improved.
