A multiprocessor computer system is provided having a multiplicity of sub-systems and a main memory coupled to a system controller. An interconnect module, interconnects the main memory and sub-systems in accordance with interconnect control signals…

OLTP与OLAP的介绍 数据处理大致可以分成两大类:联机事务处理OLTP(on-line transaction processing).联机分析处理OLAP(On-Line Analytical Processing).OLTP是传统的关系型数据库的主要应用,主要是基本的.日常的事务处理,例如银行交易.OLAP是数据仓库系统的主要应用,支持复杂的分析操作,侧重决策支持,并且提供直观易懂的查询结果. OLTP 系统强调数据库内存效率,强调内存各种指标的命令率,强调绑定变量,强调并发操作: OL…
