Hi, Probably u should try couchdb! its a document oriented database. ( apache.couchdb.org) u can store your dictionaries as json documents and yes they are simple text files; data structures cna be directly stored into JSON documents. memory efficient too.. python module @ http://code.google.com/p/couchdb-python/
