The paper analyzes the data features of fuzzy relational database on the basis of fuzzy set theory, and gives the formulized description of fuzzy relation.

模糊关系数据库的研究和应用还处于试验阶段，有关模糊关系数据库的概念模型、模糊数据的特点及其关系也尚无定论。

It has some specialties as follows:Unsymmetrical lip contour model was used to extract the information of pouting;Chinese pronunciation of vowel and consonant was enhanced to improve the dynamic process;considering the developing of lip-reading techniques,this database was fit for expanding.

不同于现有的数据库，该数据库的设计具有以下特点：采用了非对称唇形轮廓模型，提取了嘴唇突出度的信息；针对汉语音节的特点，增强了汉字音节中信息变化过程；兼顾未来唇读技术的发展，以音节为基本元素，具有可扩充性。

This is the curriculum database operations, including the more commonly used database functions.

这是数据库课程的大作业，包括较为常用的数据库的功能。

Transaction database contains more redundant data, which greatly affected the extraction of frequent itemsets.

关联规则的Apriori算法，在频繁项集的过程中要多次扫描数据库，而事务数据库中含有较多的冗余数据，极大地影响了频繁项集的提取效率。

EDINA UPDATE is a bibliographic database of land-based literature whose focus is more practical than scholarly.

爱丁堡大学数据图书馆UPDATE数据库是一个与土地利用有关的文献数据库，它的数据类型偏向于实用性。

The system numbers all struts using newfashioned digital recognition component -information button which is anti-jamming, corrosion-resisting, easily numerated and written, The portable data acquisition instrument on-site collec...

该系统采用一种抗干扰、防腐蚀、易读写的新型数字识别器件—信息钮扣对所有支柱进行编号，由便携式数据采集器现场采集、存储支柱编号及时间，并通过RS232／RS485转换器与计算机进行数据通信，将支柱信息准确、实时地传输到计算机的支柱数据库，由中文管理软件系统对数据库进行自动处理，实现信息查询、支柱报警、费用统计、报表显示与打印等功能。

Moreover, A hybrid algorithm, ALHybrid, which is made of the algorithm LIDBSO and the algorithm AprioriIpv, is designed. Two algorithm, MQC_Apriori and MQC_LIDBSO, are given to mining multiple level quantitative association rules with item constrains. Two algorithm, PMARⅡ and PMARⅢ, which are based on different sequential mining algorithms, are given for parallelling mining association rules. In order to solve the mining association rules problem when we add a set of data to a database or delete a set of data from a database, two incremental updating algorithm, EUAR and EUAR, are given. Three incremental updating algorithm for association rules mining, DIUAⅠ, DIUAⅡ and DIUAⅢ, are dedigned to solve the three kinds of association rules incremental updating problem in distributed databases.

另外，文中还设计了一个算法LIDBSO与算法AprioriIpv相结合的混合采掘算法ALHybrid；对于多层次、带约束、多值属性关联规则的采掘问题，给出了两个采掘算法：算法MQC_Apriori和算法MQC_LIDBSO；在关联规则的并行采掘方面，还设计了两个基于不同顺序关联规则采掘算法的并行算法：算法PMARⅡ和算法PMARⅢ；在关联规则的增量式更新问题上，还给出了两个改进算法：算法EUAR和算法EUARˉ，分别用于解决当数据库增加或删除一个数据集合时的关联规则增量式更新问题；针对分布式数据库中的关联规则增量式更新的三类问题，提出了三个增量式更新算法：算法DIUA Ⅰ、算法DIUAⅡ和算法DIUAⅢ。
