STUDY EXPRIMENT TO DESIGN E-R MODEL

AIM To design an Entity-relationship model. PROCEDURE STEP 1: Start STEP 2: Specify attributes and identify the primary key for Entity. STEP 3: Formulate the relation between entities. STEP 4: Ensure that all the entities have been modeled. STEP 5: Normalize the entire model. STEP 6: Stop DESCRIPTION OF ENTITY-RELATIONSHIP SYMBOLS 1. Rectangle  It represents Entity Sets 2. Ellipse  It represents Attributes 3. Diamond  It represents Relation Set 4. Lines  It represents Link between attributes to entity set and entity set to relationship set. 5. Doubled Ellipse  It represents derived attributes. 6. Dashed Ellipse  It represents primary key 7. Double Lines  It represents participation of an entity in a relationship set. 8. Weak Entity Set  An entity which does not pass any attribute for primary key 9. Strong Entity Set  An entity which passes a dominant parametric feature for unique identification.

E-R MODEL FOR BANKING ENTERPRISE

Result: Thus the E-R Model has been studied and acquired the knowledge.
