Portfolio Reflection Questions:

1. What does it mean to say that data is 'persistent'?

• Data is 'persistent' because it survives in the computer system after the process that has created it ended. (ie. when the program is shut down)

2. What's the difference, in terms of where data is located, for data stored in a global variable vs. data stored in a database?

• For a global variable, the data is stored in the RAM, so it's temporarily available. However, in a database the data is stored permanently on the computer. This way the data will be permanently kept on the computer so it can be accessed even when the user shuts down the app.
