You cannot create database in Qt. You can use Qt to create database in Sqlite, mysql or sqlserver etc.
you need to look at QSqlDatabase.


I need to add objetcs in database and restore they in the next execution
please go through some basic sql commands and basic undertanding of database.
If you create a table in database. that will be there forever. unless you forget to commit or drop it manually.


but i don't know how i restore this information when the program is re-opened
You need to use select query and show it in your application.

steps:
1.create table
2.insert data [after this you can close the application. the data will be stored in database]
3.select data [you need to select the records from database]
4.show in your app

hope it helps

In order to restore the values from the database while execution, you need to use the SELECT command of the database in the default constructor.
