Why joins cannot be supported in a NoSQL database?
Even on distributed Sql databases. It is not that joins cannot be supported in a NoSql database. It is just that the database is not designed to be efficient for joins (I’ll explain why), and hence there is no point in supporting joins.
Should I use MongoDB or NoSQL for database joins?
As your tables grow in size, the joins can become expensive. However, data in NoSQL databases is typically stored in a way that is optimized for queries. The rule of thumb when you use MongoDB is Data is that is accessed together should be stored together.
How is data stored in NoSQL databases?

What is a single node in NoSQL?
A single node is a Virtual Machine or even a physical machine. The NoSQL database will be running across a cluster of nodes so it can perform query and data storage distribution. As a distributed system, NoSQL databases offer some benefits in availability and scalability that a single SQL database does not.
