地籍圖形資料庫物件導向資料模式化之研究

Object-Oriented Data Modelling for Cadastral Graphical Databases

摘要


地籍圖形資料庫的多目標應用需要複雜的資料模式。傳統的資料庫系統因系統設計架構上的限制不能滿足此項需求。本文提出以物件導向式資料庫系統來建立地籍圖形資料庫的方法,並設計-物件導向資料模式來發展此圖形資料庫。本研究使用物件結構分析與物件行為分析方法來推導應儲存在圖形資料庫中之物件的資料結構與操作程序。比資料模式化的研究成果可做為未來以物件導向式資料庫系統發展地籍測量資料庫管理系統的基礎。

Multiple-purpose applications of cadastral graphical databases require a complex data model. Traditional database systems cannot meet this requirement due to the limitations of its design architecture. This paper presents an approach to construct a cadastral graphical database using object-oriented database systems, and designs an object-oriented data model for developing the graphical database. The research employs the methods of object structure analysis and object behavior analysis to derive data structures and operational behavior of objects required in the graphical database. The research result of the data modelling can be provided as a foundation for the development of a cadastral surveying database management system based on object-oriented database systems in the future.
