Summary: |
Applications often require data to be persistent for longer than the application remains running and longer than one user interacts with the application.
Examples of such data include:
• The contents of your web application, such as product information in a web store
• User details, such as login in information ( more about that next week)
• Data that stems from users interacting with your application that the application wants to retain for a longer period of time, such as how long a user is active on your site or which products they have looked at. |
