Design and construction of three-tiered database system for liver transplantation

目的设计并构建适合国内肝移植实际情况的数据库系统,探讨利用数据库技术进行肝移植数据管理、临床研究应用、多中心应用的可行性及前景.方法进行肝移植数据库系统的可行性及临床需求分析,采用MicrosoftSQLServer作为后台数据库,利用Dephi进行编程设计应用程序,应用于临床,测试系统性能.结果完成了数据库、服务器端与客户端应用程序及相应的数据转换、自定义查询工具的构建,已投入临床使用.结合互联网可实现多中心联合应用.结论肝脏移植数据库管理系统能够显著提高肝移植数据的管理和分析效率,同时提供临床决策支持,结合多中心可实现国内肝移植的登记与数据分析、整理,具有良好的实用价值和应用前景.

AIM： To design and construct a three-tiered database system for liver transplantation, to explore the application of the database system in data management, clinical study and muhicenter sharing in the field of liver transplantation. METHODS： Requirements and feasibility of the liver transplantation database and blueprint of the data structure was designed and accomplished based on the analysis of liver transplantation data flow. Microsoft SQL Server was used as the background database. Delphi was adopted for programming. Performance test was carried out for clinical application. RESULTS： Along with the relevant data transforming and user-defined querying utilities, the database, the server and client application were built up and applied to clinic. Combination of network realize the muhicenter data sharing. CONCLUSION： The system, which can support clinical real-time decision, remarkably increases the efficiency of data management and analysis, and is expected to have important clinical application significance and prosperous future.
