DAOFactory.getDbManager

[Himai Minh]

In Roberto buddy's DataTest class, he wrote a DAOFactory class and a getDbManager method to load the database file.
Can I load the db file in my own way?
In my instruction.html, I don't see any " must " requirement that we must have a DAOFactory class.

In my instruction.html, I don't see any "must" that says submitting any test class. Does it mean I don't need to submit my own test class?

Easy & short answers:

You can load the db file as you want

You don't have to provide/submit any test classes

You know, if I had to do everything again today, I wouldn't have a DAOFactory. The Data class wouldn't be a singleton either. I'd instantiate the Data object when the application is started, instantiate the business object, passing the Data object as a parameter in the business class' constructor, and instantiate the window, passing the business object in the window's constructor. Although the Data object wouldn't be a singleton, it would be as if it was a singleton, since it would be unique in the application.
