Introduction to MongoDB

MongoDB or you might hear people call it Mongo, is one of the most popular NoSQL database solutions to date.

It is open-source, free to use for personal and commercial use, and extremely flexible.

Programming languages such as Go ( I have a short example video of interacting with MongoDB using Go ), Javascript, and many others can interact with MongoDB using third-party modules, often being official modules from the MongoDB team.

You can read more about it here.

Here is a summary of some of its features:

• Stores data as JSON documents in schema-less collections.
• Uses Javascript as its query language.
• Has a lot of feature parity with traditional SQL databases.
• Boasts amazing horizontal scaling using replica sets.

Here is some additional information and tutorials about MongoDB from me:

Setup

• Set up MongoDB on Windows

Reading Documents

• Get all documents out of a collection
• Limit the result of a MongoDB query to one document
• How to use filters to retrieve specific documents from MongoDB
• How to retrieve a very specific number of documents from a MongoDB query

Inserting Documents

• How to insert a single document into a MongoDB collection
• How to bulk insert documents into a MongoDB collection

Aggregations

• How to count the number of documents in a MongoDB collection or query result

I will be adding a lot of posts and tutorials around MongoDB in the future. As I post them, I will add them here.
