Abstract:
Building an aspect weaver into Database Management Software(DBMS) is a key difficulty of research on Aspect-Oriented Database(AODB) systems. Based on current research results that raise weave-on-demand and weave history mechanisms, this paper gives a weaving approach implementation based on Log. This approach not only gives the concrete implementation of weave-on-demand, reweave and weaving history, but also gives individual mechanisms for fast recovery of aspect weave state when system restart normally or abnormally. This approach is a good complement and perfection for research on building an aspect weaver into DBMS.

摘要: 面向方面数据库系统研究的一个关键难点是在数据库管理系统(DBMS)中内建方面编织器。基于已有的需要时编织和编织历史机制,提出一种基于Log的编织实现方法。该方法不仅给出需要时编织、重编织和编织历史的具体实现,还分别给出系统在正常或异常重启时,基于该方法的快速恢复方面编织状态的机制。该方法是对在DBMS中内建方面编织器研究的较好补充和完善。
