You can use local storage API (see the docs for details) or expose a full blown database interface from C++.

In qt5 you can use a QObject and expose it into qml for that also :) in Qt4 the procedure is similar.

First of all you can write your own c++ class from QObject. Do your work with database in this class. Then for using this class in qml you have to register it:


qmlRegisterType<MyObject>("QtQuick", 1, 0, "MyObject");

then in your qml, just import your custom type and use it.

see this: http://qt-project.org/doc/qt-5.0/qtqml/qtqml-cppintegration-contextproperties.html for embedding qobject in qml in Qt5
