Excellent! Good luck with your project.

There's currently a very active debate going on with respect to
the merits of two libraries which offer a more SQL-friendly
interface to handle multi-index data structures (none of them is
actually SQL compatible, though.) Google for 

RML site:boost.org

to get some links to the discussion. RML site is

while RTL stuff can be found at

You can also save/load multi_index_containers contents to/from a file
via Boost.Serialization. Check
