+We have workspace level db, work as cache for tiddlers, and change logs (to record deletion, for sync deletion with mobile clients).
+
+And we have app level db, to store things for pages like workflow pages. They are also regarded as temporary cache, and user can toggle a switch to store something inside cache to a wiki.
+
+## App level DB
