面向对象的土壤地形体数字化数据库管理系统分析与设计

Analysis and Design of Oriented-objective Soil-terrian Digital Database (SOTER) Management System

利用全新的面向对象软件研制方法 ,经过分析、设计、编码和测试开发完成新的土壤 地形体数字化数据库 (SOTER)管理系统。新系统继承和扩充了原有系统的属性数据管理功能 ,增强了SOTER数据库的完整性与安全性 ;将属性数据管理、空间数据管理和模型库集成在一个系统中 ,采用Windows的图形用户界面(GUI)与用户交互 ,使SOTER数据库的建立与维扩更加方便 ;同时促进了土壤信息应用的定量化、模式化和自动化 ,也为进一步建立土壤信息系统打下了良好基础。

Newly SOTER database management system is established based on complete_newly object oriented software development method and rigorous development process of analyzing, designing, coding and examining. The new one has the following advantages: (1) inheriting and enlarging attribute data management function of original SOTER, and enhancing the integrith and safety of SOTER; (2) integrating the attribute database, spatial database and model base into a unique system, and using the windows graphic user interface (GUI), as interactive tools which make establishment and maintenance of SOTER database convenient; (3) promoting the quantitativity, model standardization and automation of soil information, and serring as a good example for building new soil databases and information system.
