主 题:re-engineering spatial-temporal database CASE tool forest stand
摘 要:The forest stand database of Bilahe Forestry Bureau, Inner Mongolia of China was taken as an example to demonstrate the whole process of building a temporal geodatabase by means of reengineering. The process was composed of establishing a conceptual data model from the initial database, constructing a logical database by means of mapping, and building a temporal geodatabase with the help of Computer-Aided Software Engineering (CASE) tool and Unified Markup Language (UML). The results showed that as the reengineered forest stand geodatabase was dynamic, it could easily store the historical data and answer time related questions by Structured Query Language (SQL), meanwhile, it maintains the integrity of database and eliminates the redundancy.
