Transactional consistency

Transactional consistency refers to ensuring that a series of actions or changes within a system are complete, correct, and reliable. Think of it like a bank transfer: either the entire process succeeds, transferring money from one account to another, or it doesn’t happen at all—there’s no partial update. This guarantees the system stays accurate and trustworthy, even if something goes wrong during a process. In essence, transactional consistency maintains data integrity by making sure that all parts of a transaction are properly completed or not applied at all.
