If you've an immediate business problem to solve get your external prog to
create perfectly formed gnc import files, that way you can get on with
doing the important stuff and solve any API issues at your leisure.
Imports are only fiddly if you are doing them as a one off, done regularly
they are efficient.

Meanwhile if you're familiar with relational databases
https://wiki.gnucash.org/wiki/images/8/86/Gnucash_erd.png
can be a good starting point.

I strongly recommend looking at Sebastien's work if you are going to be
looking at gnc from an sql POV in a non-trivial way, start here:

Warning: discussion of writing to a gnc database in an unapproved way may
result in tears.
