Slony-I is enterprise-level "master to multiple slaves"
replication system with cascading and failover.
The big picture for the development of Slony-I is to build
a master-slave system that includes all features and
capabilities needed to replicate large databases to a
reasonably limited number of slave systems.
Slony-I is developed as a system for data centers and backup
sites, where the normal mode of operation is that all nodes
are available.

The ZODB package is a Python object persistence system.
It provides the Z Object Database separately from Zope so
it can be used in non-Zope related Python applications to
provide transparent object-oriented persistency.
The Python SQL Toolkit and Object Relational Mapper
SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that
gives application developers the full power and flexibility of SQL.
It provides a full suite of well known enterprise-level persistence
