For each weak entity type W in the ER schema with owner entity type E, move all the simple attributes (or simple components of composite attributes) of W as attributes of W. O c. For each weak entity type W in the ER schema with owner entity type E, create a relation R & include only derived attributes (or derived components of composite attributes) of W as attributes of R.
