Chapter 17. Data Management and Object Persistence
THE MODULES IN THIS CHAPTER ARE USED TO store data in a variety of DBM-style database formats. These databases operate like a large disk-based hash table in which objects are stored and retrieved using unique keys represented by standard strings. Most of these modules are optional Python extensions that require third-party libraries and must be enabled when Python is built. See Chapter 27, “Extending and Embedding Python,” for further details.
