The multiple-database model can be used to work around the conflict situations inherent in long lunation database sessions.Since each user from the shared database and work against.

多个数据库模式可用来围绕长期数据库对话所固有的矛盾形势而工作，因为每一个用户可从共用数据库拷贝数据这不同于他／她的专用数据库，该数据库与共用数据库至少在表面上分开，这样用户就能避免矛盾形势。

This Memory Resident Database Supply these features: Definition of data(table、index、queue et), operation of data; synchronization of data: Data synchronous abilty is pivotal function to distributed DBMS(synchronization of static data, dynamic synchronization between master processor and slave processor); database power-on; Saving and Loading of database etc.

根据系统设计的要求该内存数据库提供以下功能：数据定义，数据操作（数据的插入、删除、修改、查询）；数据的同步机制：数据的同步功能是数据库系统保证分布、备份数据系统一致性的关键(各模块之间的静态数据同步、主备MP大量数据的动态数据同步、MP间动态数据同步)，其中本文主要介绍了主备MP的动态数据同步；数据库系统并发性控制。

Based on the Fact Sheet: Journal Selection for Index Medicus/MEDLINE and the Fact Sheet: Response to Inquiries about Journal Selection for Indexing at NLM, this article was to introduce the MEDLINE database, the process of applying a journal to be indexed in the MEDLINE database and review process. Meanwhile, this paper was to share Tzu Chi Nursing journal Editor's experiences in applying the Tzu Chi Nursing Journal to be indexed in the MEDLINE database, and hopefully these experiences can provide other nursing publishers with a reference.

本文参考「MEDLINE期刊筛选条件之说明」与「申请加入国家医学图书馆资料库之说明」此两份文件，兹对MEDLINE资料库、申请加入MEDLINE资料库之过程以及审查过程做一简明介绍，同时也分享慈济护理杂志总编辑向「美国国家医学图书馆」提出申请「慈济护理杂志」加入MEDLINE资料库之经验谈，期望此经验可做为其它护理杂志社的参考。

In the design and implementation of the database applications part,this paper introduces a method of progressive expansion to design concept structure of the database, and put forward the "pseudo-code" to solve the existing problem in modification complexity and large data redundancy after using the traditional method of normalization theorem to process the database.

在该系统数据库设计与实现部分，本文介绍了运用逐步扩张的方法设计本数据库概念结构过程，并提出了"伪码"的概念以解决利用传统规范化理论处理后数据库存在的修改复杂、数据冗余度大的问题。

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

关系数据库上的关键词检索已成为数据库和信息检索领域的研究热点之一现有数据库关键词检索系统可分为在线和离线两大类，它们都难以兼顾查询效率和效果：在线系统能够获得数据库最新结果，但速度较慢；离线系统使用预处理提高查询速度，但若数据库更新就要重新执行预处理。

The first method defines sample database by artificial operation, the second method builds one sample database and one potential sample database by the sample\'s self- training method. Some potential geometric regions are obtained by using a simple fast Hough arithmetic.

同样通过简单的快速Hough算法获取一些潜在几何区域，用对二值图像的块匹配方法对潜在的矩形区域进行识别并把它分类变成几种比分板和广告块。

Currently, research of parallel databases mainly focuses on relational database, and parallel environments are always based on special parallel architectures. With the rapid expanding of the markets of object-relational database, requests to parallel processing are increasing screamingly Certainly it will be significant to build a parallel objectrelational database. But it is a challenging work too.
