Python MongoDB Interface

Python MongoDB Interface

MongoDB is a database based on distributed file storage. Written by the C + + language. Designed to provide scalable, high-performance data storage solutions for WEB applications.

At the same time, MongoDB is a product between relational and non-relational databases and is a good implementation of NoSQL.

This document uses the Pymongo module to invoke MongoDB with Python

Summary

With Mongdb, you can access the data collection as a table, on the other hand, the type of the entry can be a JSON-like unstructured data that corresponds exactly to the dict in Python, so it's easy to use
