No flames from me: I don't know C# so I can't participate in any C# vs.
It sounds like you use C# for the bulk of your programming, and only
break out into C++ for special purposes, so it's fair enough that you
don't want to access a database from C++.
Quince is designed for people who treat C++ as their home, and one of
its purposes is to save them the trouble of going outdoors. I dare say
that the same applies to sqlpp11.
Quince also has another purpose (and this is also for people who treat
C++ as their home): it allows them to rethink the boundary of what is
"database access". By making it easy to use the DBMS's data-processing
features, in C++ syntax and with C++ data types, it lets a C++
programmer continually renegotiate the division of labour between the
DBMS and his application. It may be that a programmer already has a
solution for what he calls "database access" today, but maybe the
boundary of his "database access" would shift if he had a different tool.
