transaction <DAO definition>

Microsoft DAO 3.60

transaction

A series of changes made to a database's data and schema. Mark the beginning of a transaction with the BeginTrans statement, commit the transaction by using the CommitTrans statement, and undo all your changes since BeginTrans by using the Rollback statement.

Transactions are optional and can be nested up to five levels. Transactions increase the speed of operations that change data and enable you to reverse changes easily.

Transactions are global to the referenced database object's Workspace.
