Database Design Document Template

The Database Design document maps the logical data model to the target database management system with consideration to the system’s performance requirements. This document converts logical data constructs to the tables and files of the target DBMS.

Use this template to:

Define the basis for the application’s database design.
Provide expected data volumes, functional and non-functional usage of the tables, and performance considerations and requirements.
Ensure that every database transaction meets or exceeds its performance requirements.
