Abstract:

In combination with the framework of Three Gorges Reservoir Area's Geological Hazards Data Warehouse and the data characteristics of the geological hazards,the paper presents a set of ETL process for building geological hazards data warehouse.A detailed study is made of the critical technologies such as data extraction,transformation,and loading.The ETL process of geological hazards data warehouse is exemplified by a landslide.

Key words: three gorges reservoir area;geological hazards data warehouse;ETL
