Transaction

A Transaction is a platform mechanism that treats multiple state changes as one execution boundary, committing them on completion or restoring a consistent state on failure.

Not applicable. Transaction does not define the UML classification of Classes or Objects.

CML can describe operation preconditions, postconditions, invariants, and state changes. Concrete Transaction boundaries are designed by separating domain meaning from platform realization.

Scala can implement Transaction control, but a language-level function call or exception boundary is not automatically a Transaction boundary.

simplemodeling-lib provides contracts for states, constraints, and results, but no single generic Transaction runtime is treated as this term’s canonical definition.

Japanese videos introduce the term as トランザクション(transaction).
