Abstract:
Equipping a three-dimensional (3D) simulation system with database technology provides many advantages: Simulation models can be managed more efficiently than with files, temporal databases can be used to log simulation runs, and active databases provide a means for communication. Thus, we use a central database to share simulation models from different fields of application from space missions to forestry. To enable real-time access, each simulation client caches the model to its local runtime simulation database. For that purpose, each pair of databases must be synchronized. After a synchronization on schema level, each client replicates data on-demand. In this publication, we present an approach that uses both databases' notification services to keep master copies in sync with their replicate copies. State machines are used to model the approach.
