The application of distributed database technology in books data management system 分布式数据库技术在图书资料管理系统中的应用
To logically look into and update the errors in the distributed databases on the whole is the key issue for the technology of distributed database 如何在全局逻辑上查询、更新分布在分布式数据库中的错误,是分布式数据库技术要着力解决的问题。
Distributed database is the production that was combined by the computer network and database technology . it has a many years history in database domain 分布式数据库技术是分布式技术与数据库技术的结合,在数据库研究领域中已有多年的历史。
Along with the progress of technologies in computer networks , distributed database has undergone significant development and become one of the hottest research fields 随着计算机网络技术的发展,分布式数据库技术已成为当前最活跃的领域之一。
The key technology to solve the problems which exist in webgis is using distributed computing technology , distributed database technology and distributed object technology 分布式计算技术、分布式数据库技术和分布式对象技术是解决webgis中存在问题的关键技术。
It is necessary and feasible to applied the distributed database technologies into our dlrf system considering the increasing expansion of education business and increasing resources 所以,采用分布式数据库技术构建远程教育资源框架dlrf ( distancelearningresourceframework )是必要和可行的。
The mobile database is a branch of the study of distributed database and distributed computing . the mobile database can be thought as the extend of the traditional distributed database 移动数据库技术是分布式数据库技术和分布式计算研究的重要分支,移动数据库通常可以看作是传统分布式数据库的扩展。
With the development of network technologies and distributed database technologies , they have provided the technology support for distance learning resource construction . consequently , distributed database architecture is a natural choice for it 随着网络技术的发展以及教育业务的拓展,分布式数据库技术的发展,无疑为教育资源的建设提供了技术支持。
People have studied the distributed databases for more than 30 years . in recent ten years , this technology has made great progress in trait , bank , air , railway and so on . but it is the first time to lead this technology to the high school teaching management 分布式数据库管理系统的研究开始于70年代中期,近十年以来,分布式数据库技术在商业,银行,航空,铁路等行业得到了很大发展,但将这门技术引入高校教学管理国内还没有先例。
The synchronization and replication is also an essential technology of mobile database . comparing trade distributed database environment , mobile computing environment has characteristics of high frequency disconnection , network condition diversity , network communications dissymmetry and so on 移动计算环境与传统的分布式计算环境相比有频繁的断接性、网络条件的多样性以及网络通信的非对称性等特点,这些特点使得传统的分布式数据库技术不能有效支持移动计算环境。
