The research of dynamically updated spatial database model for urban planning
Wang Lei · Cehui kexue · 2009
This paper gives an in-depth analysis of two outstanding issues in urban spatial database construction: update conflict and slow update.With reference of previous research on spatio-temporal data updating methods and the event-driven approach,this study introduces a dynamic data updating model by adding time dimension to the urban spatial database.This model addresses the concurrent data updating issues between data administration and data generation,as well as data versioning issues.The authors utilize this model in both internal and external systems,and test it in a production environment.The application results are discussed.
