查询

Processing query with materialized views must find matching of view and query. Arithmetic of query reformulation is proposed.

用具体化视图处理查询，通过发现从视图到查询的匹配来识别查询类型，提出了使用视图的查询重写算法。

"The mere fact that in order to test the truth of the representations some independent inquiry is made, which necessarily is really in the nature of a fishing expedition rather than a systematic search that will necessarily reveal the truth if carried out with reasonable thoroughness, does not indicate lack of reliance; to hold so would enable a liar who falsifies facts peculiarly within his own knowledge to subject to an unconscionable squeeze play: if makes any independent checks he would claim that it isn't 'relying' and thus is not voidable … the only alternative for the company would be to indicate 100 per cent faith and reliance by making no investigation whatsoever, at the risk of having a court later determine that inconsistencies in the application or information otherwise brought to their attention should have caused them to make at least such an inquiry as a prudent man would have made."

但如果受害方的确有去作出了查询并且发觉了这个误述，但他还是去确认合约，这就表示了另一个重要的问题就是他并没有依赖这一个误述。当然，受害方去作出查询并不代表他能够完全知悉真相，所以误述方会有很大的举证责任说明受害方完全通过查询可以知道事实真相，所以后来确认合约并没有去依赖误述。这也是现实，例如在近年来的合并收购的商业活动蓬勃，其中涉及了不少的卖方被指控向买方作出误述。但在这种交易，买方通常会在订约前会来一个"合理努力"的查询/查帐，岂非是卖方就因此可以随意去误述而不必负责了？这方面美国上诉庭有一个先例把这一点说得很清楚，它是New York Life Insurance Co v。 Strudel 243 F 2d 90 (5 Cir 1957)，如下

Along with the time development, the computer technology more and more thorough various trades and occupations, have provided thorougher and a convenient service for the general users In order to realize raises department's working efficiency, uses the resources fully, reduces the nonessential manpower, physical resource and financial resource goals and so on disbursement, presented various information management system The paper will design university student's dormitory information management system's Web and realizes using the solution The university student's dormitory information management system is one safe and the highly effective proprietory system, designs specially for the information engineering institute This system has used many technologies, for instance JSP, JDBC, Web service and so on The proprietory system use's database is SQL the Server 2000 databases The university student's dormitory information management system's major function includes: May realize to the student's dormitory information inquiry function, including fast inquiry function and classified inquiry function; To the student's dormitory information's input function, the revision function, deletes the function and the statistical function Realizes the dormitory Control section through the system above function regarding the student's dormitory information current management, namely facilitates the dormitory administrative personnels to keep abreast of the student lodging situation and the billeting situation comprehensively promptly; Has provided some simple data inquiry for the user and outputs each kind of information and so on

随着时代的发展，计算机技术越来越深入各行各业，为广大的用户提供了更为周到和便捷的服务。为了实现提高部门的工作效率，充分利用资源，减少不必要的人力，物力和财力的支出等目的，出现了各种各样的信息管理系统。论文将设计一个高校学生公寓信息管理系统的Web应用解决方案并予以实现。高校学生公寓信息管理系统是一个安全和高效的专用系统，专为信息工程学院设计。这个系统使用了很多技术，比如JSP，JDBC ，Web服务等。专用系统使用的数据库是SQL Server 2000 数据库。高校学生公寓信息管理系统的主要功能包括：可以实现对学生公寓信息的查询功能，包括快速查询功能和分类查询功能；对学生公寓信息的录入功能，修改功能，删除功能和统计功能。通过系统上述功能实现公寓管理部门对于学生公寓信息的日常管理，即方便公寓管理人员及时全面地掌握学生住宿情况及公寓分配情况；为用户提供了一些简单的数据查询并输出各种信息等。

Based on the development, classification, comparation of classific algorithms of spatial indices, the paper designs two efficient spatial indices including the improved quadtree and R+tree, applies them into spatial query processing, and realizes the spatial select query algorithm based the improved quadtree and R+tree, and nearest and k-nearest neighbour query based R tree.

在对空间索引技术的发展、分类和典型算法比较的讨论基础之上，本文设计并实现了两个高效的空间索引—改进的四叉树索引和R+树索引，并将这两个索引应用到空间查询处理中，分别实现了基于改进四叉树和基于R+树的空间选择查询算法以及基于R树的最临近查询和K最临近查询算法。

Driven by the analyzing the synonymic characteristic of the key words and the intensity of semantic association among the ontology instances, we provide a user"s intention analysis scheme, which synthesizes the synonymic relation and the semantic association. The method can improve the accuracy and completeness of the mapping from key word to ontology entities, infer the user"s intent.

本文以查询关键字词义特性和本体实例之间语义关联强弱分析为切入点，提出了一种综合词义关系和语义关联分析的查询目标分析方法，提高了查询关键字到本体概念映射的完整性和准确性，帮助搜索引擎有效的确定用户的查询目标，解决了传统搜索引擎不能很好理解用户意图的问题。

And the direction query efficiency based on multi-approximate index is compared with that based on taditional external approximation index. 2 The algorithms of nearest neighbor and reverse nearest neighbor about point, line and ploygen based on multi-approximate index are proposed after the virous methods of distance measure are discussed in detail. And the query efficiency of NN and RNN based on multi-approximate index is compared with that based on taditional external approximation index. 3 The basic concept of semi-join and the strategy of distance-direction semi-join are introduced. And the model of distance relationship, direction relationship and the bounding for spatial object are discussed. Then the method is presented about how to implement the query of distance-direction semi-join, and the efficiency of the algorithm based on multi-approximate index is compared with that based on taditional external approximation index.

This paper puts forward a new Difference Group Query based on two query points, the methods in GNN query which define several query points in a MBR are not suitable for the specific Difference Group Query in our paper. In this paper, based on the algorithm in YFK-CNN, we use the definition of hyperbola, divide the query space into several sections to delete the unsuitable space, furthermore, we develop several asymptotes from the definition of hyperbola, simplify the hyperbola based filter strategy in the search space.
