ZODB provides an object-oriented database for Python that provides a high-degree of transparency. ZODB runs on Python 3.7 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.
