What problems are you trying to solve? You've jumped into Jannick's thread about importing, but none of this seems germane. Why would you want to save GC's xml into a db? What would you do with it then? Many people already keep their GC files in Dropbox or similar for access from multiple machines and or for offsite backup. Works fine. Gnucash *probably* writes things to the XML file in the same order that they were read in just because we use linked lists for just about everything internally, but there's no guarantee of that and it might well create excessive churn in a version control system. But we already rename the loaded XML file and write out a new one, so you can easily back up a bit. NoSQL isn't a good fit for accounting data. Neither is XML, actually. Relational databases were invented specifically for accounting programs. GnuCash already has a SQL backend that can communicate with MySQL and Postgresql servers and we intend to make GnuCash a proper RDB/SQL application with all queries to the RDB instead of sucking everything into memory as we do now. The XML backend will convert to creating an in-memory SQLite3 RDB at startup which gets written back out to XML for saves. If you want to develop something, join the team and work on that. We'll be working in C++ for new code, but there's plenty of work to do in C as well.
