Answer 1

A database with default data and table structure is often prebuilt and included in the assets folder. We then copy this from the assets folder to the internal or external storage at runtime, as the assets folder is ready only after compile time, and we cannot modify the data in it. Therefore, to be able to write to the database form our app, we must first copy it to a part of the storage we can access.

Answer 2

Sometimes, you may want to have db with prepared data. Think about address book, or zip code things. If you don't put that information in asset folder, building basic information would be a pain (Of course, you can get data via network, but that's not the point)
