Core Data Model

[Soham]

I’m working on a personal financial app with Core Data, however, I’m a little puzzled because I’m accustomed to working in a DBMS environment.

The issue is that I’ve opted to employ four entities in the Data Model: Expense, Income, Goal, and Recurring. However, it appears that such entities have no link with one another.

I attempted to add a new entity named Balance to connect Income and Goal, but it appears that it is still unnecessary because the object would not be used as explained by the example here.

Is it possible for me to join those four entities? Is it feasible to establish entities in the same Data Model that do not have any relationships between them? Should I instead develop a new Data Model for each of the entities?
