#Python 프로그래밍 언어로 #NoSQL도 다룰 수 있죠 :) 여러 오픈 소스 중 #MongoDB 오픈 소스 데이터베이스를 직접 설치하여 #Flask 를 통해 테스트해보는 과정을 #Azure 환경에서 어떻게 하는지를 보여주고자 하였습니다.

NoSQL – type and examples
• non-SQL / non-relational approach / Not only SQL
Source: https://en.wikipedia.org/wiki/NoSQL

4. [Open Source Programming] Data Store – NoSQL with Python: Getting Started
NoSQL with open sources – e.g., MEAN stack
• M: MongoDB
• E: Express.js
• A: AngularJS
• N: Node.js
• Why NoSQL in MEAN Stack?
• For programs that use JSON-
like BSON (binary JSON)
documents with schema
• MongoDB supports its use of
JSON-like documents for
interacting with data as
opposed to the row/column
model
