MongoDB is an open source database management system (DBMS) that uses a document-oriented database model that supports numerous kinds of data. While this is true, relational databases use tables and rows, but MongoDB architecture is formed of collections and documents. MongoDB stores data in JSON-like documents that can vary in structure.

Schemaless — The Dark Side – Mahesh Paolini-Subramanya – Medium

“We store everything as JSON, that way we don’t worry about schema” — #CowboyDeveloper

Schemaless is not an excuse to scatter your data-persistence rules throughout your code— you still figure out these rules, and you still need to implement them coherently!

Precog: Analytics Machinery

Precog

The world's most advanced analytics engine for NoSQL data is now 100% open source!

Modern APIs and apps don't speak in flat, tabular data. They speak JSON.

Precog is the analytics engine that natively handles JSON. It's easy for developers to integrate and comes with a high-level tool called Labcoat that lets data scientists and analysts deeply analyze their data.

Precog can store any kind of JSON data, from primitive values, to records, to complex, large documents with lots of nested objects and arrays.

Precog does not impose any schema on your data. Every value you store in Precog can be different from every other value.

APIs for everything, including ingest, queries, and security (accounts and API keys); and client libraries for all common languages.

Build queries on your JSON data with Labcoat (a visual query builder). Do everything from data munging to analytics and machine learning.

Considering the fast evolution of NoSQL databases, the topic is now very old (from 2010). But read the comments on the original post, Hacker News, and Reddit to see what people think today about extreme denormalization, schemas, relational and NoSQL databases.

Imagine you like to record if a person is pregnant or not. In old SQL times all men had a pregnant entry ^_^ (which was always false afaik)
