X/Open XA

X/Open XA is a set of standards designed to manage and coordinate transactions across multiple computer systems and databases. It ensures that all parts of a transaction either complete successfully together or are all rolled back if any part fails, maintaining consistent data. Think of it like a referee in a multi-player game, ensuring all players follow the rules and the game stays fair. Used mainly in enterprise systems, XA allows different databases and resources to work seamlessly within a single, reliable transaction, enhancing data integrity across complex IT environments.
