Database Implementation for Distributed Computing of Dynamic Behavior of Spatio-temporal Objects
The current researches on spatial data models are not focused on behavioral features.In these resear-ches,the way of modeling entity spatio-temporal features and behavioral processes separately lacks the description of individual behaviors,which is difficult to apply to the expression of dynamic behaviors of pluripotent autonomous individuals,and the realization of dynamic behaviors at the individual level often requires a large amount of compu-ting.To solve the above problems,a database implementation that supports dynamic behavior distributed computing from the underlying structure based on the Multi-granularity Spatio-temporal Object Data Model is proposed to unify the description and structured storage of the internal states and behavioral capabilities of spatio-temporal entities from an individual-oriented perspective in this paper.A"hybrid"data storage architecture and a storage strategy of"master-slave"database are adopted to optimize data storage and management,which provides basic support for the realization of dynamic behavior of spatio-temporal objects.The results of the case study show that the imple-mentation of the database can change the way of treating dynamic behavior as process simulation and provide effec-tive support for the distributed computing of dynamic behavior of spatio-temporal objects.
