Another good one is yserial, also using SQLite: http://yserial.sourceforge.net/ "Serialization + persistance :: in a few lines of code, compress and annotate Python objects into SQLite; then later retrieve them chronologically by keywords without any SQL. Most useful "standard" module for a database to store schema-less data. The module is instructive in the way it unifies the standard batteries: sqlite3 (as of Python v2.5), zlib (for compression), and cPickle (for serializing objects). If your Python program requires data persistance, then y-serial is a module which should be worth importing. All objects are warehoused in a single database file in the most compressed form possible. Tables are used to differentiate projects. Steps for insertion, organization by annotation, and finally retrieval are amazingly simple..." -Jeff _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
