2018-12-15 · Whereas ACID is pessimistic and forces consistency at the end of every operation, BASE is optimistic and accepts that the database consistency will be in a state of flux. Although this sounds impossible to cope with, in reality it is quite manageable and leads to levels of scalability that cannot be obtained with ACID.

Formally, ACID refers to a set of properties a database system maintains during transaction execution. These properties are: Atomicity: Transactions are indivisible units, such that all of their effects apply, or none of them do. An ACID transaction should meet some defined rules for data validity before making any updates to the database otherwise it should be aborted and no changes shall be made to the database. All database transactions are considered as a single logical operation and during the execution time the database is put in an inconsistent state until the changes have been committed.
