SQLObject is an object-relational mapper, i.e., a library that will wrap your database tables in Python classes and your rows in Python instances. It currently supports MySQL through the 'MySQLdb' package, PostgreSQL through the 'psycopg' package, SQLite, Firebird, MaxDB (SAP DB), MS SQL, and Sybase. It should support Python versions back to 2.4.
Python bsddb3 is a Python module that provides a nearly complete wrapping of the Oracle/Sleepycat C API for the database environment, database, cursor, sequence, and transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. It has complete support for Berkeley DB distributed transactions, and complete support for the Berkeley DB Replication Manager and base replication API. The goal is to mirror most of the real Berkeley DB API.
python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly, it wraps the OpenLDAP 2.3+ libs for that purpose. Additionally, the package contains modules for other LDAP-related stuff (such as processing LDIF, LDAPURLs, and LDAPv3 schema).
IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters, and companies. It can retrieve data from both the IMDb's Web server and a local copy of the whole database. The IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package.
Modeling Framework fills the gap between the Python object world and relational databases in that it allows users to transparently create, retrieve, update, or delete Python objects from a database without having to write a single line of SQL. Its main features include generation of database schema, generation of Python code templates ready to be used, support for transparent mapping of (class) inheritance in relational databases, object-oriented query language, use of standard Python getters to traverse relationships (the related objects are automatically fetched when needed and when appropriate), and automatic checking for referential-integrity constraints, etc. Supported databases are MySQL, Oracle, PostgreSQL, and SQLite.
Elixir is a declarative layer on top of SQLAlchemy. It is a fairly thin wrapper that provides the ability to define model objects following the Active Record design pattern, and using a DSL syntax similar to that of the Ruby on Rails ActiveRecord system. It does not intend to replace SQLAlchemy's core features, but instead focuses on providing a simpler syntax for defining model objects when you do not need the full expressiveness of SQLAlchemy's manual mapper definitions.
