The Live mode of an {{UBIK}} object model is trimmed on managing complex data models with large amount of data. So it is the mode of choice once you want to provide a data model for productive use, since it leverages the scalability features of the underlying database. However, in contrast to the [[Sandbox mode]], it is not as flexible since changes in the Metamodel require a download and restart of [[UBIK]].
Use the [[Class Browser#Context menu|Class Browser's]] context menu to switch the mode of a [[MetaClass]]. Once a MetaClass is switched into Live mode, all its instances are in Live mode as well.
