Real-Time Capable Data Management Architecture for Database-Driven 3D Simulation Systems

State of the art 3D simulation applications like virtual testbeds for space robotics, industrial automation or even forest inventory require a highly flexible but still real-time capable data management system. For this, we combine a high-performance internal simulation database with external object-oriented databases into a new real-time capable data management architecture for database-driven 3D simulation systems. To achieve this, we apply well-known database techniques to a 3D simulation system’s internal object-oriented data management. Such a simulation database can dynamically adopt completely new data schemata, even at runtime. New simulation applications can then be designed by putting a domain specific schema and the corresponding data into an otherwise ”empty” simulation database. To seamlessly combine the two databases we use a flexible interface that synchronizes schema and data.
