The Entity-Relationship Model (Classic Reprint): Toward an Unified View of Data: Toward an Unified View of Data (Classic Reprint) - Softcover

Inhaltsangabe

Explore how the entity-relationship model shapes database design and data organization. Learn why this framework helps separate business concepts from data structures.

The book presents the entity-relationship model as a way to capture what the real world means for data. It explains how entities, relationships, and attributes are defined, and how these ideas translate into diagrams and data structures. You’ll see how a unified view of data can support data description, manipulation, and integrity across different modeling approaches.

Through clear sections, the author outlines multilevel views of data, introduces a special diagrammatic technique, and compares the entity-relationship model with network, relational, and entity-set models. The goal is to help readers reason about data in practical terms and apply the model to real database design challenges.

• Learn the four levels of logical views of data and how they relate to modeling choices.


• Understand entities, relationships, attributes, and value sets, and how they map to databases.


• See how entity-relationship diagrams guide design and support data integrity.


• Compare the entity-relationship approach with relational and other data models.

Ideal for readers of database theory and practitioners building robust data systems.
