Changing database in MIT App Inventor

Hi,

I am building my own mit app inventor from the open source, GitHub - mit-cml/appinventor-sources: MIT App Inventor Public Open Source.

I am able to run the application in my local device, as far as I understood the projects which are created in the application are stored in the local database with the path
"appengine/build/war/WEB-INF/appengine-generated/local_db.in".

Can some help me, whether I can change the database to some other (Ex: Mongodb).
