ZODB - A Python object-oriented database

ZODB provides an object-oriented database for Python. It does not require separate language for database operations. It has very little impact on your code to make objects persistent. It also does not require database mapper as using an object-relational mapping is not like using an object database. Its feature include ACID support, Pluggable layered storage, Caching, Binary large objects (Blobs) and lot more.
