An implementation of persistent object store for real-time systems with strict processing time constraints is a challenging
task, because many traditional database techniques, e.g. transaction management schemes, are not applicable for such systems.
This paper examines technical and business requirements for one particular class of such systems and describes an architecture
based on distributed shared virtual memory. The major contributions are: use of distributed dynamic hashing to achieve load
balancing and tight coupling of transaction and virtual memory management, which allows local scheduling of read-only transactions.
