中文摘要：
本文介绍了Oracle 10g拓扑数据模型中基本元素和拓扑实体两种对象间的构成关系,提出了依据内部映射关系实现模型对象一体化编辑的思路,分正向和逆向两个一体化编辑过程,解决了单方面编辑其中一种对象产生的拓扑实体对象构成成分或拓扑关系正确表达、冗余数据出现、编辑不完整或不能完成等问题。给出了应用实例和实现关键技术。实践证明,这种一体化的编辑,能有效的保证模型对象编辑的一致性与正确性。
英文摘要：
This paper introduces the structural relationship between basic element and topology geometry in Oracle lOg Topology Data Model. Based on the inner mapping relationship of them, a thought of implementation for integrated editing is given, which includes positive and negative processes. This idea can solve the correct expression of structural component or the topology relationship in topology geometry, the occurrence of redundant data, the imperfectness or the incompleteness of editing. Finally, a study case and key techniques are presented to prove that this idea can effectively ensure the consistency and correctness for editing works.
