systems).
In other words, each user statement is executed in its own transaction In other words, each user statement is executed in its own transaction
and commit is implicit (if execution was successfull). and a commit is implicitly performed at the end of the statement
(if execution was successful, otherwise a rollback is done).

i.e. all user statements after <command>BEGIN</command> command will i.e. all user statements after <command>BEGIN</command> command will
be executed in single transaction untill explicit COMMIT, ROLLBACK be executed in a single transaction until an explicit COMMIT, ROLLBACK
or execution abort. Statements in chained mode are executed much faster, or execution abort. Statements in chained mode are executed much faster,
because of transaction start/commit requires significant CPU and disk because transaction start/commit requires significant CPU and disk
activity. This mode is also required for consistency when changing activity. Execution of multiple statements inside a transaction
