基于主动对象/行为图的主动面向对象数据库建模机制的研究与应用

摘要

概念建模主动面向对象数据库时,UML基于对象结构/对象行为这种二维机制,将主动行为和被动行为都作为同样的对象行为来建模,这显然不能完整地反映主动面向对象数据库的三维概念模式:对象结构、主动行为和被动行为.提出使用主动对象/行为图这一建模工具来拓展UML,借以基于对象结构/主动行为/被动行为这种三维机制概念建模主动面向对象数据库.%When conceptually modelling the active object-oriented database, the two dimensional mechanism of UML based on object structure/object behaviour deems the active behaviour and passive behaviour all as the same objects behaviours while modelling, it is clearly to be failed to intactly reflects the three dimensional conceptual pattern of active object-oriented database: the object structure, the active behaviour and the passive behaviour. This paper suggests to use the modelling tool of active object/behaviour diagram to expand the UML, and makes use of this three dimensional mechanism based on object structure/active behaviour/passive behaviour to conceptually model the active object-oriented database.
