Editing Round-trip engineering (section)

=== Auto synchronization ===
Another characteristic of round-trip engineering is ''automatic'' update of the artifacts in response to ''automatically'' detected inconsistencies. In that sense, it is different from forward- and reverse engineering which can be both manual (traditionally) and automatic (via automatic generation or analysis of the artifacts). The automatic update can be either ''instantaneous'' or ''on-demand''. In instantaneous RTE, all related artifacts are immediately updated after each change made to one of them. In on-demand RTE, authors of the artifacts may concurrently update the artifacts (even in a distributed setting) and at some point choose to execute matching to identify inconsistencies and choose to propagate some of them and reconcile potential conflicts.
