Hi Parth,
The ER diagram related to LiveCycle ES is something, that is Adobe Specific and any changes to its dependencies is never advisable and neither is supported. However, related to the LC ES ER diagram, even if one can develop the ER using various tools available in the Open Source market, it is difficult to understand the complete architecture of it, without complete knowledge of the architecture and its dependencies, constraints.
If you would be more specific in telling about which table constraints or which module specific you want to analyze then it would be better to pick up only that section of the DB ER for analysis.
Please find attached couple of screenshots that I have related to the LC ES DB ER diagrams.
Let me know if it helps.
Cheers!
Pushkar
