As a result , spatio - temporal object - oriented data model and moving object data model behave more strongly in the expressions of the spatio - temporal objects 结果表明,面向对象数据模型和移动对象数据模型在时空对象的表达上体现了较强的能力。
The diagram of core ' s parts was shown in datail . the object - orient data modals were written detailedly togther with the realizing of components of the core 文章详细描述了内核的构成部件,介绍了内核面向对象数据模型设计,给出了具体的内核部件实现。
The object - oriented data model is transformed to relationship data model by means of the translation of relationship tables in oodbms to conventionally data definition language in rdbms 在设计阶段,通过将面向对象中的关系表用传统关系数据库的数据定义语言来描述,从而实现了面向对象数据模型向关系型数据模型的转换。
4 based on the theories puted forward above and the design goal of the symbol editor , this paper introduces a series of designs and implements such as the data model of symbol objects , the structure of system 4 、在上述理论的基础上,以符号编辑器的设计目标为依据,详细叙述了在开发编辑器的过程中,符号对象数据模型、系统的框架结构等方面的设计与实现。
Hence , it is imperative to improve and expand it . this paper will research modeling method of workflow system , designing and storing method of object data model , transaction execution , and version control of resource combined with characteristics of engineering design 本文结合工程设计项目管理的应用特点从工作流系统的建模方法、对象数据模型的设计及存储方案、事务执行机制以及资源版本控制等方面进行技术研究。
