Pytables is a hierarchical database package designed to efficiently manage very large amounts of data. pytables is built on top of the hdf5 library and the numpy package. it features an object-oriented interface that, combined with natural naming and c-code generated from pyrex sources, makes it a fast, yet extremely easy to use tool for interactively save and retrieve large amounts of data.

- compound types (records) can be used entirely from python (i.e. it
is not necessary to use c for taking advantage of them).
- the tables are both enlargeable and compressible.
- i/o is buffered, so you can get very fast i/o, specially with
large tables.
- very easy to select data through the use of iterators over the
rows in tables. extended slicing is supported as well.
- it supports the complete set of numpy, numeric and numarray objects.
this package contains the extension built for the python 2 debug interpreter.
