Actually, the new NumPy can work as a very-good fast and efficient simple in-memory database (or memory-mapped data-base for that matter). The elements of a NumPy array can be arbitrary records. You would search using logical combinations of comparision. I think the ability for NumPy (which now handles arbitrary records) to be used as a data-base is under-appreciated. Mind you, it is SQL-less. NumPy only provides the "tables" it does not provide the fancy logic on-top of the tables. So, perhaps it would be better to say that NumPy could serve as the foundation for a simple data-base application. -Travis -- http://mail.python.org/mailman/listinfo/python-list
