-/**
- * An interface for front-end database classes. The classes should prepare the
- * objects for saving in the database. So for server-bases database classes SQL
- * queries shall be generated and send to the backend classes. In case of local
- * file databases the object shall be serialized and (maybe) transparently
- * compressed before they got saved to a local file.
