A database management system, also called a DBMS, allows users to create a new database by specifying the logic structure of the data. For instance, the world of interest is represented as a collection of tables in relational DBMSs. This simple model is useful for many applications, and ...
This paper describes a computer-cluster based parallel database management system ( DBMS ), InfiniteDB, developed by the authors. InfiniteDB aims at efficiently support data intensive computing in response to the rapid growing in database size and the need of high performance analyzing of massive ...
The maturation of database management system (DBMS) technology has coincided with significant developments in distributed computing and parallel processing technologies. The end result is the emergence of distributed database management systems and parallel database management systems. These systems have beco...
In subject area:Computer Science A Parallel Database refers to a database system that stores data in parallel databases with the same structure as operational databases, requiring upgrades to reflect changes in data structure from the operational database. This strategy involves upfront costs for exp...
dbms_parallel_execute包是把大表分成了多个小的chunks,然后对chunks进行并行,这个就类似把非分区表变成了分区表。 注意,该包是Oracle 11g 以后才有的。 二. 使用说明 以下内容转自: http://www.oracle-base.com/articles/11g/dbms_parallel_execute_11gR2.php ...

In Distributed Database System, data is physically stored across several sites, and each site is typically managed by a DBMS capable of running independent of the other sites. In contrast to parallel databases, the distribution of data is governed by factors such as local ownership and increased...
这个PL/SQL包,是11.2引入的新特性,关于他的语法,可以参考《Oracle® Database PL/SQL Packages and Types Reference 11g Release 2 (11.2)》的101章DBMS_PARALLEL_EXECUTE。另外,在MOS的这篇文章《11.2 New Feature : Using DBMS_PARALLEL_EXECUTE to Update Large Tabl...
Data Placement in Parallel Database Systems The way in which data is distributed across the processing elements of a parallel sharednothing architecture can have a significant effect on the performance of a parallel DBMS. Data placement strategies provide a mechanical approach to ... S Zhou,MH Wil...
This Chapter continues to follow the spirit of integrating data mining and parallel processing, as presented in the previous Chapter, but it goes further in that it adds DBMS facilities to the picture. The basic motivation is that most large data warehouses are already stored on parallel databa...
