【摘要】 描述了面向对象应用与关系数据库之间的高性能对象持久层的系统结构,重点阐述了其Cache的关键技术。提出了分别针对LOB属性和常用查询的分布式与集中式两层Cache结构,给出了具体的Cache实现,并分析了Cache一致性问题的解决。该Cache实现技术使系统性能得到很大的提高。更多还原

【Abstract】 This paper describes a high-performance architecture of a object persistent layer,which is a middleware between object-oriented application and RDBMS.This paper focuses on the Cache techniques and proposes a two-tier Cache architecture,in which one tier is used for LOB attributes and the other for frequent queries.Solutions of the Cache consistency problems are also introduced.System performance is greatly improved by this Cache architecture.更多还原
