If you ever wondered what happens behind the scenes in Enterprise Architect you should have a look into this book. It's the prefect map for the twisty little passages, all alike in EA. The current issue has been updated to match the new GUI found in V12. This book shows details of what is at the low level of EA: its database. The information gathered in this book is a summary of what has been found out by quite a number of EA users including me. If you need to dive into details which the official API does not provide, this book is what you might have been looking for. This book starts with a short introduction on how to query EA’s database. This is followed by a concise list of all available tables and details for the most important ones. The details contain cross references into more details as well as screen shots of the GUI where the appropriate elements appear. Vice versa the screen shots point to the according table columns. The final sections conclude with a practical approach to using SQL in Enterprise Architect.
