Improving the data model and service

To improve our app, let us review the use cases again. We are developing a cross-platform password manager app that is compatible with the popular KeePass database format. We have the following use cases:

• Use case 1: LoginPage – As a password manager user, I want to log in to the password manager app so that I can access my password data
• Use case 2: AboutPage – As a password manager user, I want to have an overview of my database and the app that I am using
• Use case 3: ItemsPage – As a password manager user, I want to see a list of groups and entries so that I can explore and examine my password data

• Use case 5: NewItemPage – As a password manager user, I want to add a password entry or create a new group in my database
