pyndb, short for Python Node Database, is a package which makes it easy to save data to a file while also providing syntactic convenience. It utilizes a Node structure which allows for easily retrieving nested objects. All data is wrapped inside of a custom Node object, and stored to file as nested dictionaries. It provides additional capabilities such as autosave, saving a dictionary to file, creating a file if none exists, and more. The original program was developed with the sole purpose of saving dictionaries to files, and was not released to the public.

Basically, it's a way to treat internal hash tables like real databases, with automatic saving, automatic creation (if the file doesn't exist already), and so forth.

A fast NoSQL DB, that uses the same RESP protocol and capable to store terabytes of data, also it integrates with your mobile/web apps to add real-time features, soon you can use it as a document store cause it should become a multi-model db. Uses Redis' network protocol so it's a drop-in replacement. Has some helper functions built in. Aims to be easy to use, with minimal configuration.
