SQL-Database Documentation

[Johannes Pinger]

Dear GnuCash-Team!

1. Sorry about my English, English is not my foreign language, so there 
will be a few mistakes :)
2. Really love your software :D

I have thought about developing an app for gnucash for my android 
device. To start, i checked the different file formats where the data is 
stored in. I would like to work with the sql3 files, but I haven't found 
any documentation about it yet. So is there any documentation?

I'm looking forward to a feedback!
