Show me your flowcharts and conceal your tables, and I'll continue to be mystified. 
Show me your tables, and I won't usually need your flowcharts; they'll be obvious.

-- The Mythical Man Month by Fred Brooks

Even after four decades, and long after the word "flowchart" has been replaced by "UML", data models still play a central role in software design. The following three books will give you three different perspectives on data modeling for enterprise applications and help you understand the heart of opentaps. You should read all three to get a balanced perspective:

• Data Model Resource Book, Volume 1. -- This comprehensive volume and approaches it from a relational perspective for transactional systems.
• Domain Driven Design -- This book approaches the design of transactional applications from an object-oriented perspective.
• The Data Warehouse Toolkit -- This book gives a comprehensive treatment from the analytical perspective.

There are also a couple of books about OFBiz on Amazon:

• Apache OFBiz Development
• Apache OFBiz Cookbook

Other helpful references:

• Open Source Licensing -- If you want to learn more about open source software licenses, read this book instead of all the mailing list graffiti.
• Don't Make Me Think, or I will hate your user interface.
