ZODB, a Python object-oriented database

Latest release Supported Python versions Build status Coverage status Documentation status

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.
