This paper presents a totally generic client-server model for accessing legacy and new databases according to the three tier architecture principles. It is based on an integrated environment that eases the dynamic creation and instantiation of secure web applications that access multiple database management systems. Emphasis is placed on the ability to query almost any type of relational database and queries can simultaneously address a multitude of data sources. The information is collected, assembled and presented to users depending on a possible set of user profiles. These profiles originate from work on securing the conduct of clinical studies. This has been achieved in the context of the EU funded project HARP (Harmonisation for the Security of Web Technologies and Applications). The generic character of the model is exploited through an accompanying set of development tools. This permits efficient and effective creation and maintenance of applications in several domains of health telematics and beyond. Main merit is the lightweight character of the resulting platform, whereby all necessary instantiations are accomplished through a set of related XML documents.
本文提出了一种完全通用的客户端-服务器模型，用于根据三层架构原则访问遗留数据库和新数据库。它基于一个集成环境，该环境便于动态创建和实例化访问多个数据库管理系统的安全Web应用程序。重点在于查询几乎任何类型关系数据库的能力，并且查询可以同时处理多个数据源。信息根据一组可能的用户配置文件进行收集、组装并呈现给用户。这些配置文件源自保障临床研究开展安全的工作。这是在欧盟资助的项目HARP（Web技术与应用安全协调）的背景下实现的。该模型的通用性通过一组配套的开发工具得以利用。这允许在健康远程信息处理及其他多个领域高效且有效地创建和维护应用程序。主要优点是所得平台的轻量级特性，即所有必要的实例化都通过一组相关的XML文档来完成。
