【摘要】 Web的易用性和实用性，使它成为目前使用最为广泛、最有前途的信息传播技术。Web技术已经从一种仅仅提供静态HTML网页内容的站点技术发展成为一种在全球范围内进行创造、提供信息、进行协作和商业活动的系统工具。综合信息服务系统正是基于Web技术蓬勃发展起来，已成为企事业单位提高综合管理水平，增强竞争力的有力工具。 本文首先论述了综合服务系统的概念，Internet和Web产生与发展，以及目前常用的Web开发技术；其次，对Web数据库系统和系统实现中使用的一些关键技术进行讨论，并对中间件技术进行深入的研究。阐述了中间件的概念、工作原理、分类和开发架构，分析设计并开发了一个数据库中间件，提出当前数据库中间件的不足和一个解决方案。最后，采用B／S／S三层体系结构模式，采用JSP技术、中间件技术以及Web数据库技术，分析设计并开发了研究生综合信息服务系统。系统使用中间件技术提高了开发效率和开发质量，提高了代码的重用性，减轻了代码维护的工作量；采用数据库连接池技术提高了数据库的访问效率；把Tomcat嵌入Apache中提高了Web服务的质量；并分别从操作系统、数据库服务器和应用系统三个方面探索了加强系统的安全性。系统经过实际使用，满足了用户的要求、达到了预期的目标。更多还原

【Abstract】 Web is an information technology that has being in most wide use and is promising attribute to its availability and practicality. Formerly, Web was a technology only supporting static HTML page, but now it is a tool to present global information resource, carry out cooperation and business activities. On the basis of Web technology, integrated information service system gradually developed, and now has became a strongly tool to improve integrated management and competition ability of enterprise.Firstly, this paper described the concept of the Integrated Information Service System, the creation and development of Internet and Web, and the technology in common use of Web programming. Secondly, the paper discussed the key technology of Web database system and system realization, and deeply studied the middleware technology. As an emphasis, this paper introduced the concept, work theory, categories and system infrastructure of middleware, point out the shortcoming of current database middleware, and brought forward a solution to solve the problem. Lastly, making use of JSP, middleware and Web database technology, the author designed and realized the Graduate Integrated Information Service System based on B/S/S three-layer frame. By the use of middleware, this system improved its programming efficiency and code reusability, reduced the workload of code maintenance. The access efficiency of database was improved because of the use of DB Connection Pool, and the Web Service quality was improved through the combination of Tomcat and Apache. In addition, the security of system was enhanced from OS, DB Server and application system. Several months’ practical use proved that the system completely meets the demand in the practice.更多还原
