databases

I think I'm simplifying things too much.. A significant service a
database provides is a guarantee of consistency: 

  A database transaction, by definition, must be atomic, consistent,
  isolated and durable. These properties of database transactions are
  often referred to by the acronym ACID.

In relation to persistence, this is not trivial.
