Abstract
Embodiments of the invention relate to memory management methods and systems for object-oriented databases (OODB). In an embodiment, a database includes a plurality of memory-mapped file segments stored on at least one nonvolatile memory medium and not in main memory. An application program connects to the database with a plurality of writing processes to simultaneously write to an in-memory database, each writing process updating its own disk-based logfile, such that the effective disk writing speed is substantially increased and lock conflicts reduced.
