The active storage framework is a hierarchical object database modeled after the object database of Userland Frontier (in spirit, not in format). It is based on an SQL database backend (currently PostgreSQL is available) that is used for efficient storage of objects but uses a Frontier like way to access elements in it. It has rich data types for storage of Python values, and is tightly integrated in the Python attribute and dictionary access syntax. Its query algebra allows efficient hierarchical queries, and will be compiled on usage into SQL queries.  [edit]  Less
