In this paper, we present several ideas while inquiring how to apply CASE tools to CIM process effectively, and propose five proper applicable paradigms to enhance the possibility of applications that the CIM process may make better use of CASE tools.展开更多

From the viewpoint of software architecture, this paper first presents TBus architectural style, which is a kind of CASE environment architectural style based on ToolBus, then describes the architectural model and system's behavior in formal method, researches and analyzes the corresponding tool structural model. Last the paper implements a TBus architectural instance-LambdaBridge, which proves the validity of ToolBus and TBus architectural styles.展开更多

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.展开更多
