数据库

Each process will use its own local XA database connection, and the database ensures that all the distributed updates made in the same distributed transaction from different processes will be committed atomically.

每个过程会使用自己的本地 XA 数据库连接，并且数据库确保所有的分布式更新在同一个分布式事务中产生，从不同的处理会被原子化提交。

This paper researches the basic principle of fuzzy retrieval on multimedia data semantics, designs a fuzzy reasoning mechanism of Agent knowledge base, puts the fuzzy algorithm wich reasoning is forward or backword,and relevant implementation is presented as well.

引 言目前计算机科学的许多研究正沿着&智能化&的方向发展，多媒体数据库的复杂查询正面临着新的挑战〔1〕。因此，将语义学、多 Agent系统、知识库、模糊理论、人工智能等领域知识综合，运用于多媒体数据库数据语义的模糊检索，有着极其重要的研究意义。

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。

Methods A systematic literature search of PubMed,MEDLINE,BIOSIS,EBM Reviews and Chinese Journal Full-text Database between January 1990 and May 2007 was performed for relevant published studies.

方法检索PubMed、MEDLINE、中国期刊全文数据库等国内外数据库。

Bitemporal database design is a method of storing time dependant data records to represent both the history of the facts and the history of changes to the records in the database.

时态数据库设计是一种存储数据记录的时间依赖，同时代表事实的历史，在数据库中记录的更改历史的方法。

Firstly, working on the data model of temporal-relation, a bitemporal data model on object-relation is proposed in this paper, which may be implemented in current object-relational databases.

首先在现有时态关系数据模型基础上，提出了一种基于对象关系双时态数据模型，而这种数据模型适合于在现有数据库平台上实现；其次，在该模型框架内，讨论了时态对象关系模式与时态关系模式相互间的联系与转换，这也是由时态关系扩充到对象关系的基本要求：再次，分析了时态模型中时态变量复杂语义和相应绑定算法，这是时态数据库能够有效运行的基本课题

The temporal variable "Now" always presents in HRDM or BCDM , while "UC" presents only in BCDM, HRDM is TDB which can represent valid time, while BCDM is a bitemporal database model which can represent both valid time and transaction time.

本文对于TDB发展历史中典型模式进行研究，对于历史数据库和双时态数据库中的时间变元进行分析，有针对性地对它们的时间变元进行了绑定操作。

Even though databases fetch data blindingly fast, you should still try to reduce the load on the database by only selecting that data which you need to use.

尽管数据库取数据非常快，你需要试着减少数据库的负载，通过只选择你需要的数据。

This tool was used to build the most complete diversity database of Braconidae in China, which consists of 731 taxa (including 569 species) and 128 keys.
