Good to know about NoSQL

• NoSQL is non-relational

• ACID-compliant (only just recently with MongoDB)

  • Atomic/Atomacity: A change will not be saved but rolled back unless the entire transaction is completed.
  • Consistency: No intermediate state from one valid state to another. Always valid states.
  • Isolation: The effect of more than one concurrent transactions is the same as if they happen in sequence.
  • Durability: The data is there no matter whether database is shutdown, failures or crashes.
