Non-relational databases

Other paradigm of storing data in a database is to use NoSQL database. NoSQL tables are much simpler than SQL tables and faster too, because validation of records is not done by the database but by front-end. The code needs to ensure that record that is being inserted has proper relationships.

NoSQL databases are much simpler than SQL databases. If SQL databases require vertical scaling in order to handle additional load, then NoSQL databases can be scaled horizontally by adding more systems. These systems can perform differently, please be aware that slower machines will be performing slower than fast machines.

Example of NoSQL databases are: MongoDB, CouchDB.
