Atlassian Connect Express (ACE) - access database in addon

[Ovidiu Munteanu]

I have started working on an addon using the Atlassian Connect Express (ACE) framework and I was wondering if there is a prescribed way to access the database from other parts of the add-on. 

More specifically, should I be using ACE's internal instance of Sequelize, create a new instance, or some other way. 

If I am to use ACE's internal instance of Sequelize, I am not entirely clear how to do that since it doesn't seem to be exposed in any of the app's properties, or am I missing something?

Any help would be appreciated, thanks!
