Need External Database Or We Can Use Shopify Database To Store Shopify App Data

[RasedulRussell]

Hello @All  

Hope teams are doing well.

Problem:

Merchants install a Shopify App and make some configurations. App owners can store the configuration data in the Shopify database server or need an external database server for the App.

I am new to Shopify app development. Can anyone provide me with some documents or other resources, that help me to take the decision?

Regards,
