Understand how enterprise data fits together and how to design it for real-world change.

This book presents a practical approach to modeling data for large organizations. It uses the Entity-Relationship framework to describe how entities, relationships, and attributes connect in an enterprise view, and it shows how diagrams can reveal how changes affect the design. The text explains common operations on the schema and provides concrete examples to help you plan and adapt your data model over time.

Key ideas include comparing ER diagrams with other modeling methods, handling changes in mappings and structures, and guiding you through steps from conceptual design to a usable database schema. You’ll see how to approach shifts such as adding or deleting entities, relationships, and value sets, and how to reason about moving elements between conceptual domains.

How to represent real-world data with entity sets, relationship sets, attributes, and value sets

Ways to modify a schema through add, delete, split, merge, and shift operations

How shifting between conceptual domains affects the data model and its diagrams

How ER diagrams compare with data-structure diagrams for enterprise design

Ideal for students and professionals seeking a clear, practical foundation in data modeling for complex organizations.
