Hello Santosh, you do not need to have a DB entry stored for every permission. Your realm can interpret your domain model and create permissions "on the fly" without accessing the DB.
Tauren sketched out [1] how she does that for her application and I have to say I like her approach. Kind regards, DJ [1] http://n2.nabble.com/Roles-and-permissions-td3272609.html#a3272609
