Databases, Storage

“If wealth is lost, nothing is lost

If health is lost, something is lost,

If character data is lost, everything is lost”

-Anonymous

A great playwright with a Shakespearean name once said, “All the world’s a database, And all the men and women merely records”.

Data[bases] drive[s] the world. They are the sum of human knowledge, and all around the world many an overworked DBA (DataBase Administrator) spend endless, sleepless nights just keeping these things running. There is currently talk going on of Transforming the Web into a database.
Here is the sum of my database knowledge, starting with ACID:

A single logical operation on data is called a transaction. The ACID set of properties guarantee that database transactions are processed reliably:

  • Atomicity
  • Consistency
  • Isolation
  • Durability

(Reference: ACID at Wikipedia)
