物件導向式地籍圖形資料庫系統的分析與設計

Object-oriented Analysis and Design for the Development of a Cadastral Map Database System

摘要


隨著物件導向資料庫科技的進展,特別是物件導向資料庫管理系統(OODBMS),提倡以物件導向的方式來處理複雜的空間資料正逐漸增加中。本文提議利用一個遵從物件資料庫標準ODMG-93 OODBMS做為發展地籍圖形資料庫管理系統的核心。而欲發展物件導向式地籍圖資料庫系統,必需先以物件導向分析與設計方法建立一地籍物件體系。因此本文著重在地籍圖形資料的基本物件、物件關條及物件體系等之建立工作。此外,本研究亦使用一個商用的OODBMS建立一原型系統以實際驗設系統發展的潛能,此資料庫設計的研究成果可做為未來發展高效能的地籍物件導向式資料庫管理系統之基礎。

With the advent of object-oriented database technology, especially of object-oriented database management systems (OODBMS), the promotion for handling of complex spatial data in an object-oriented manner has been increasing. In this paper, an ODMG-93 object database compliant OODBMS is proposed as the kernel of a data management system for cadastral map. In order to develop an object-oriented cadastral map database system, it is necessary to construct a cadastral object hierarchy by means of object-oriented analysis and design. Thus, this paper emphasizes on the construction of fundamental objects, object relationships and object hierachy for cadastral map data. Furthermore, a commercial OODMBS was used to build a prototype system to demonstrate the potential of system development, the research result of the database design may be provided as a foundation for the development of a more efficient map database system for management of cadastral map data.
