1) transaction data set
事务数据集
2) data transaction
数据事务
1.
This paper offers a exposition of the design of the self-developed system of visual ship data,in which the new technology of Autodesk DWF was imported to develop 3D ship figure,JNI technology was applied to actualize the integration of figure,the technology of PRO*C,Hibernate and View were used to dispose figure data,and the data transaction was used to protect the security of system.
在船舶数据可视化系统中,引入新技术Autodesk DWF开发3D船舶图形,应用JNI技术对图形进行集成,利用PRO*C技术以及Hibernate、视图等技术来对数据进行处理,同时利用数据事务对系统的安全进行保护。
3) data flow transactions
数据流事务
4) transactional database
事务数据库
1.
Based on these supersets and union sets,some theorems and corollary about reducing transactional database and an AprioriNEW algorithm are established.
该算法利用每趟挖掘中一些非频繁项集的超集、并集,逐步约简事务数据库中的事务,提高了关联规则的挖掘效率。
2.
Based on distributed transactional database system constructed by P2P,the paper extends the most classical algorithm Apriori.
基于以P2P网络模式构建的分布式事务数据库,对Apriori算法进行了推广。
5) transaction database
事务数据库
1.
In order to mine association rules, it used frequent 1 itemset to reorganize the transaction database.
为了快速挖掘关联规则,分析了挖掘关联规则的Apriori算法,并在此基础上给出了一种改进的算法:NApriori算法,利用频繁1项集重新组织事务数据库来挖掘关联规则,此方法仅需扫描数据库2次,且避免了Apriori算法繁琐的连接和删除步骤,实验结果表明此方法比Apriori算法有更好的性能。
2.
To update original association rules when a new transaction database is added to the original database and the minimum support threshold and minimum confidence threshold are kept unchanged, a simple and high-efficiency incremental updating algorithm for mining association rules is presented.
针对一个新的事物数据库加到原有的事务数据库中,在最小支持度和最小置信度都不变的情况下相应关联规则的更新问题,提出了一种简单高效的增量式关联规则挖掘算法。
6) Database Transaction
数据库事务
1.
Database Transaction manipulation is very important in database programming.
数据库事务操作是数据库应用程序开发中非常重要的操作,通过正确的事务操作可以控制数据的完整性。
补充资料：事务
①事情：料事务，察民俗｜办理机关事务｜事务繁多。②琐碎繁杂的具体工作：事务主义者｜整天陷在事务堆里不能自拔。③世事，社会情况：世间事务｜不谙事务的孩子｜他又住在这山旮旯子里，外间事务，一概不知。
