    SQL vs NOSQL

  SQL: relational, NOSQL: non relational
  SQL: universal but defined schema
  NoSQL: unstructured dynamic schema
  SQL is vertically scalable, increased resources of one machine
  NoSQL is horizontally scalable, increase number of machines
  NoSQL can become larger and more powerful
  NoSQL does not require a DBA (Database Administrator)
    
      flexible and high performing
