综合自然环境数据模型设计与数据库实现

Design of Data Model and Implementation of Database for Synthetic Natural Environment

建立环境数据模型是综合自然环境建模与仿真中的重要一环,本文讨论了环境数据模型的概念和构建数据模型的方法,采用一种基于面向对象和场相结合的方法构建了环境数据模型,并根据此模型进行了数据库实现。

Constructing the Environment Data Model (EDM) is a key step of the Modeling and Simulation of Synthetic Natural Environment (SNE). In this paper, the definition of EDM and methods for constructing EDM are discussed, then a method which combines the Object Oriented technology and the data field concept is adopted to construct the EDM, and finally the environment database is implemented based on this method.
