                                                                                                      I am willing to store objects in a database. The purpose is to be able to read / write these objects with the program. The requirements are the following:

                                                                                                      • Objects can be complex using Qt classes such as QList, QString ... or even can contain other objects that use QObjects
                                                                                                      • The database should not be readable or modified by human (no text file, and if I use sqlite database, it has to be encrypted in a way)
                                                                                                      • I should be able to remove, read an object by its name and count the number of objects in the database, without loading everything in the memory

                                                                                                      I asked a question here, to do this with a QDataStream with a minimalist example. But it seems it is not the best way to proceed. Would you have some suggestions regarding the solutions that exist for this purpose?

                                                                                                      I have tried the following but it does not fulfill the requirements:

                                                                                                      • Storing text in sqlite with QtSQL: but the data is accessible by using sqlitemanager for example, can be modified or removed by humans. Moreover, I have no idea regarding the way to store QList for example or other objects that I created and contain QObject (for example, 2 QList)
                                                                                                      • Storing binary data using QDataStream: in this case, I cannot count the number of objects in my file, neither read or remove a specific object without loading the entire file in memory.

                                                                                                      I would be grateful if you could give me some suggestions or provide example, even if the example is minimalist.

                                                                                                      I finally found a solution, especially thanks to Igor Tandetnik and thanks to the topic here

                                                                                                      I haven't quite finalized, there is a small imperfection because I have to define an object of my user class that I don't use in order to call the readFromDB function to generate my object from the db.

                                                                                                      On the other hand, I get this error message "QSqlDatabasePrivate::addDatabase: duplicate connection name 'qt_sql_default_connection', old connection removed" each time I call my database.

                                                                                                      Anyway, it's a bit late now, and I think it might help some people so I post this minimalist imperfect code below. I'll post an update in the next few days.

                                                                                                      Thanks again.
