aha .. that sounds like you're better off not using any kind of database product ..
Next question is the programming language you want to use because * e.g. in C++ and Java there are serializer libraries which will reduce the job

   to almost no code or libraries that encapsulate XML ... * PL/I and C would be o.k. in a way that you can use recursive data structures

   (just a plain tree ...) - you could steal this from any book on data structures

   using C - there are plenty of them
* Cobol ... did it support recursion ? :-) - uuuuughh

so .. we still need some more facts here ..
