Two common problems are the lack of a versioning scheme and reliance on the object data model 两个常见的问题是缺少版本控制方案和依赖于物件资料模型。
Research on oriented object data model modeling method and application in large scale data platform 面向对象数据模型建模方法研究及在大规模数据平台中的应用
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 main works are as follows : la oodm ( oriented object data model ) for visualization in city 3d scene and information " s query is presented in this paper , according to the characteristic of city space object 论文所作的工作主要有: 1在对已有的三维空间数据模型研究成果进行讨论的基础上,根据城市空间地物的分类特点,提出了一种适用于城市三维可视化和信息查询系统的面向对象三维数据结构。
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。
