Best practice Local storage entities in core module or mobile application module

Hi everyone,

At the moment i'm working on a mobile application in OutSystems. I wonder what is best practice when it comes to creating Local Storage entities. Should i create these in my core module that I also use for creating Database entities, or should i create these Local Storage Entities in my mobile application module?


Hi Jordi,

I would say that local storage are much closer to the frontend and therefore you should put them in the mobile module. Think of this you have a core entity mapping to Opportunities for instance, which has a bunch of attributes. While for one specific mobile app you might just need the opportunity name, amount and a couple of FKs for another mobile app you might need a different set of attributes depending on the offline use case.

I hope this helps,



Hi André,

Thank you for your response. Your explanation sounds good and logical to me.
