摘要
中间件技术正成为构建大规模信息系统的热门技术.针对海量信息系统中数据规模大,数据加载速度要求高,查询处理耗时多的特点,构建了一个海量信息事务处理系统,实现了数据的并行加载和并行查询.该系统基于分布对象计算技术CORBA(C omm on O b ject R equest B roker A rch itecture)平台实现,具有高效、平台无关和在线可扩展等特点.
The middleware technique is widely used in building a large-scale information system. This article, aiming at the characteristics of the large scale and high speed of data loading, and the long-time need of a query in some massive information systems, designed a massive information transaction processing system and implemented its data＇s parallel loading and parallel query. This system is implemented by adopting CORBA middleware and provides with efficiency, platform independency and online extendibility.
