i want to create application in windows. i need to use databases which would be preferable best for pyqt application
like
sqlalchemy
mysql
etc.
If you want a relational database I'd recommend you to use SQLAlchemy, as you then get a choice as well as an ORM. Bu default go with SQLite, as per other recommendations here.
If you don't need a relational database, take a look at ZODB. It's an awesome Python-only object-oriented database.
