well.. as far as i know Microsoft Access Database is just a tool to handle MYSQL, i used Microsoft Access to write my MYSQL database for my PHP suites :]

It is good to have a database system, but maybe it should be easier to use a DLL or create a DLL that uses C++? Because there is already optimised libraries for C++ that use MYSQL :]
But maybe there is other equally good ways ^^, that’s just how I would have done it
