We have Arcade too!

I forgot to mention that Mongo is much faster than SQL. Mongo or NoSQL in general is much newer than SQL. SQL has been around for ages. Some people don't like change. Migration is costly and hard in most cases. Mongo is about availability of data whereas SQL is about consistency i.e: ACID (Atomicity, Consistency, Isolation & Durability) A lot of tutorials will get programmers using SQL initially, i.e PHP tutorials

Mongo is advantageous because it: Scales when server loads increase. Scales horizontally rather vertically making it cost effective. Stores unstructured data so developers can quickly prototype Supports nested data, i.e arrays, objects within objects. Natively supports the JSON data format, which decreases conversion overheads.
