This [[Module Library|XQuery Module]] provides functions to organize values in a persistent main-memory key-value store.
The store is useful if data (a system configuration, maps serving as indexes) needs to be repeatedly accessed. The store is persistent: Contents will be written to disk at shutdown time, and the serialized store will be retrieved from disk as soon as the store is used for the first time. The store will be stored in a binary {{Code|store.basex}} file in the database directory.
