基于XML的复杂查询在多层Web系统中的实现

Realization of the Complex Query System Based on XML in Multi-Tie Web System

用传统的基于数据库的应用系统难以实现复杂查询 ,而且可扩展性不好 .将XML技术引入到多层Web系统中 ,可以充分发挥XML文档“一次描述 ,多种使用”的优势 .实践表明 。

Traditional database system is not only difficulty to realize the complex query system, but also inconvenient in extending other query functions. By means of injecting XML into multi-tie Web system, we can develop the advantage of XML that 'interpreted at once, used in variety'. In practice, this method appeared to be very successful when it was used to realize complex query in multi-tie Web system.
