An implementation of persistent object store for real-time systems with strict processing time constraints is a challenging task, because many tra- ditional database techniques, e.g. transaction management schemes, are not ap- plicable 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 vir- tual 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.
