TAILIEUCHUNG - Database System: Chapter 6 - Relational Database Design by ER- and EERR-to-Relational Mapping

Database System: Chapter 6 - Relational Database Design by ER and EERR-to-Relational Mapping presents about ER-to-Relational Mapping Algorithm, Mapping EER Model Constructs to Relations (Options for Mapping Specialization or Generalization, Mapping of Union Types (Categories). | Chapter 6 Relational Database Design by ER- and EERR-to-Relational Mapping Copyright © 2004 Pearson Education, Inc. 5/14/2020 4:10:15 AM Chapter Outline ER-to-Relational Mapping Algorithm Step 1: Mapping of Regular Entity Types Step 2: Mapping of Weak Entity Types Step 3: Mapping of Binary 1:1 Relation Types Step 4: Mapping of Binary 1:N Relationship Types. Step 5: Mapping of Binary M:N Relationship Types. Step 6: Mapping of Multivalued attributes. Step 7: Mapping of N-ary Relationship Types. Mapping EER Model Constructs to Relations Step 8: Options for Mapping Specialization or Generalization. Step 9: Mapping of Union Types (Categories). Slide 6 - ER-to-Relational Mapping Algorithm Step 1: Mapping of Regular Entity Types. For each regular (strong) entity type E in the ER schema, create a relation R that includes all the simple attributes of E. Choose one of the key attributes of E as the primary key for R. If the chosen key of E is composite, the set of simple attributes .
