主存数据库系统设计与实现的其它部分还包括数据库文件格式和数据库进程调度的原理。
In addition, the realizing parts of the MMDB system include database file format and the theory of database process schedule.
本文介绍GKD - MMDB主存数据库管理系统的系统结构和主要内部数据结构及实现算法。
This paper describes GKD-MMDB, with emphasis on its architecture, data structures and implemented algorithms.
根据主存数据库的数据分布情况，设计了数据库数据的各种同步传输协议，实现了维护模块的设计。
All kinds of synchronization transport protocols were designed in the light of the data distributing of the MMDB system, realized the function of database maintenance module.
然而，对于简单网格，仍然需要数据库作为主存储。
For simple grids, however, a database is still required for primary storage.
顾名思义，内存中数据库完全驻留在主存中，而不是磁盘上，这使得数据访问比传统的基于磁盘的数据块要快一个数量级。
As the name implies, an in-memory database resides entirely in main memory rather than on disk, making data access an order of magnitude faster than with conventional, disk-based databases.
而另一方面，客户可能在主存储中有一些重复的数据库，但却不会太多。
In primary storage, on the other hand, your customer may have some duplicate databases but not much else.
主存空间数据库需要相适应的空间索引。
该算法通过分组及时舍弃挖掘过程中生成的非频繁项目集，有效降低主存压力，减少对数据库的扫描次数，能够对时变数据库进行高效地关联规则挖掘。
The stress of main memory is abated, the times of scan of database are cut down, and the algorithm executes more efficient mining of association rules in time-variant database.
该方法包括以下步骤：在对数据库进行更新之前取得主存储器中的主要数据库的前映象；
The method includes the steps of taking a before-image of the primary database in main memory before an update to the primary database;
该方法包括以下步骤：在对数据库进行更新之前取得主存储器中的主要数据库的前映象；
