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.

thank you for your reply,
please give tell example program or sites sir ...

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");

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

To copy to clipboard, switch view to plain text mode 

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

see this: http://qt-project.org/doc/qt-5.0/qtq...roperties.html for embedding qobject in qml in Qt5
