Physical database design Logical database design 2.1 ER modeling (conceptual design) 2.2 View integration of multiple ER models 2.3 Transformation of the ER model to SQL tables 2.4 Normalization of SQL tables (up to 3NF or BCNF) *result: global database schema, transformed to table definitions 3. ;��� ey�K�>��$ށ����g/�쀝����dt�-����b�QsT� �J�Ӻ?f����X"���aa.��6TBI�u|H���xƖ ��\' �E�b) %PDF-1.2 %���� In this tutorial, you will use SQL Developer Data Modeler to create models for a simplified library database, which will include entities for books, patrons (people who have library cards), and transactions (checking a book out, returning a book, and so on).
