Thread: Can PostgreSQL be used in a C++ application
Hello: I am developing an application using VDK which is C++ wraper over gtk+. Can someone tell me if I can use PostgreSQL in this application. Is there PostgreSQL++ for C++?

thre is a libpq++ that is installed by default as long as -disable-CXX wasn't used to configure ...

Wenhao,
The short answer to your question is "yes and no." The slighly longer
answer is learning how a database application goes together.
There are three major components to a database application. From the top
down they are:
1.) The user interface (UI). In your case, you are using gtk+.
2.) The middleware. This is the glue which connects the UI to the database
engine. In your case it's C++.
3.) The database engine. This is where postgres resides. It is the back
end of your application and works with almost any front end and middleware.
Plan your application so that each component is handled separately. You
can develop the postgres back end and the UI front end completely
independently of each other. Your middleware (C++ for you, C for me) is the
glue which connects the two.

Most user interfaces are in C++ (MFC and Qt), so can I mix C++ (MFC or Qt) with C functions (maybe Libpq and my own functions)??? Could you give-me samples???
