To be on the 100% safe side, you should create a separate module
translating "database schema of product A" to a randomized schema of the
same items/facts used in the product B and release that module under the
GPL. It should look like this:
//--- (internal GPL'd header)
struct t_scheme_under_the_GPL {
A a;
B b;
C c;
};
//--- (external header)
struct t_scheme_freed_from_the_GPL {
C a_your_name;
A b_your_name;
B c_your_name;
};
void make_me_free(const void * scheme_under_the_GPL,
t_scheme_freed_from_the_GPL * p);
//--- (GPL'd implementation)
void make_me_free(void * g, t_scheme_freed_from_the_GPL * p) {
p->a_your_name = static_cast<t_scheme_under_the_GPL *>(g)->c;
p->b_your_name = static_cast<t_scheme_under_the_GPL *>(g)->a;
p->c_your_name = static_cast<t_scheme_under_the_GPL *>(g)->b;
}
Hth.

too, whereas GNU cannot.)
