  • If you put it on a Database, all Daos and Entities in that database will be able to use it.
  • If you put it on a Dao, all methods in the Dao will be able to use it.
  • If you put it on an Entity, all fields of the Entity will be able to use it.
  • If you put it on a POJO, all fields of the POJO will be able to use it.
  • If you put it on an Entity field, only that field will be able to use it.
  • If you put it on a Dao method, all parameters of the method will be able to use it.
  • If you put it on a Dao method parameter, just that field will be able to use it.
