I just meant the specific workflow you'd like to use, not a full magit 
tutorial.  I just need a simple recipe to follow.  ;)

I've often thought of this as well.  I had always hoped someone would 
write a nice elisp interface to a database so I could do just the 
semanticdb part.

Semanticdb was designed so that it can use any storage mechanism, and if 
a storage mechanism has a faster way to do something, it will use that 
mechanism.

If there is an sql version, you can just set 
semanticdb-new-database-class to your sql class, and it will defer to 
that for all storage.  If not, the old file based db will work.

The CEDET test suite uses the non-file storage version as the backend 
while running tests to avoid updating or accidentally pulling in data 
from previous runs.

There are also examples of pulling tags from Emacs for elisp, from .jar 
files from Java, and a few others.

Sounds like a nice extra layer for when the sql backend is active.
