ZODB: a Python object-oriented database

ZODB provides an object-oriented database for Python that provides a
high-degree of transparency. ZODB runs on Python 2.7 or Python 3.4 and
above. It also runs on PyPy.

- no separate language for database operations
- very little impact on your code to make objects persistent
- no database mapper that partially hides the database.
  Using an object-relational mapping **is not** like using an
  object-oriented database.
- almost no seam between code and database.
ZODB is an ACID Transactional database.
