Swordfish is a persistent database which uses javascript object notation (json) over http. it was designed to complement a relational database used in modern web applications by providing a means to denormalise (and thus avoid) computationally expensive join operations.

to this end, swordfish's primary data structure is a dictionary with ordered keys and provides functionality for atomically manipulating and querying these structures, including set-based operations such as intersection and difference.

this package contains a convenient wrapper for projects using the django web development framework.
