TinyDB is document oriented database written in pure Python.

TinyDB is a query processing system for extracting information from a network of TinyOS sensors.

Unlike existing solutions for data processing in TinyOS, TinyDB does not require you to write embedded C code for sensors. Instead, TinyDB provides a simple, SQL-like interface to specify the data you want to extract, along with additional parameters, like the rate at which data should be refreshed -- much as you would pose queries against a traditional database.
