Chapter 3 Building Physical Diagrams


Physical Diagram Basics

A physical diagram allows you to define a database structure from the physical implementation point of view. It takes into account the physical resources: DBMS, data storage structures and software, to describe the structure of the database.

You build a physical diagram at the end of the data analysis process, before you start the software programming. The physical diagram allows you to define how data from conceptual model are implemented in the database.
