ACID, Y’ALL!! Today, we had Hashrocket do a day-long workshop about SQL, and discussed Transactions. Transactions have four qualities: Atomicity - a series of database operations such that either all occur, or nothing occurs. Consistency - start in a valid state, end in a valid state Isolation - what do others see of the WIP? the more isolation the better. Durability - when the DB commits, it’s persisted to a permanent source.
