林业数据仓库的设计

基于森林资源规划设计调查(简称二类调查)数据建立的林业数据仓库系统是以各类资源数据为对象、集成了多种加工、分析方法的软件系统。本文分析了林业数据仓库的特点，认为复杂性和时间特性是林业数据仓库的主要特点，由此在数据仓库的设计和实施过程中必须充分考虑时间序列和参数相关关系，并图示了林业数据仓库的体系结构以及建立逻辑模型和物理模型的主要方法。

Design of Forestry Data Warehouse

Forestry date warehouse is a software system which combines many methods of analysing on basis of forestry investigation information. This author analyses the features of forestry data warehouse and consides that temporal and complicated features are two main features of forestry data warehouse. The system structure of forestry data warehouse is illustrated. In addition, this paper explains the methods of implementation of logical and physical model.
