一种基于实现站点系统完整度的数据库多级查询方法

提出了站点完整度概念，并实现了其在站点设计中的应用；设计了在广域网环境下的基于实现站点系统完整度的数据库查询模型，同时给出了在该模型下将模糊查询与超媒体检索相结合的实现方法．

A database fuzzy query method based on increasing website's integrity

The thesis discusses a fuzzy query method for web database under the circumstance of fat clients.Based on the principle of general query disposal, a new concept of integrity of website is put forward, that is a soft factor of evaluation for designing of website. The integrity function is also given to describe the new concept. The thesis also discusses that with the method of fuzzy query combined with supermedia query, the term number in multilevel query will be decreased while the integrity of website will be increased effectively. A model for fuzzy query designing, is proposed and a designing formula is also put forward to meet the requirement of term number in multilevel query. In addition, a supermedia query method is also introduced in the thesis, which can implement the multilevel query effectively.
