        css.sdb.InteractionHandler is deprecated, as it does not only handle database related interactions,
        but also delegates all kind of unknown requests to a css.task.InteractionHandler.

        In today's architecture, there's only one central css.task.InteractionHandler, which is to be used
        for all requests. Depending on configuration information, it decides which handler implementation
        to delegate a request to.

        SQLExceptionInteractionHandler is the delegatee which handles only database related interactions.
        LegacyInteractionHandler is the version which first checks for a database related interaction, and
        forwards everything else to the css.task.InteractionHandler.
