Question

I am creating an application using Grails Framework for which I plan to use the database which is provided by Grails.
Just wanted to be sure of the advantages/disadvantages before proceeding.
Does using the internal database invite issues?

Thanks!

Answer 1

By default, Grails has an in-memory database, which means, that whenever you shut down your application, all your data is lost… probably not what you want.

You could change this to a file-database, and this file-database would by default end up in your Grails application root. If you deploy this to an app server and undeploy again, your data is lost… again, probably not what you want.

I would recomend installing a MySql database. It’s easy, and you have your data separate from your application.
