Is this an aggregate in DDD? Is it unnecessary to group objects as an aggregate if there are no invariants?
Below is a scenario that needs to be modeled using the Domain-Driven Design (DDD) approach. A Project can have Notes added to it. A Note cannot exist without a Project. A Note needs to be viewable individually in detail in a modal in the Project details page. Note details will be fetched asynchronously. Notes need to be editable and deletable. A Note is not viewed outside the Project details page. There are no invariants involved. One Note has nothing to do with the others. There is no limit to the number of Notes per Project. There are no other rules or objects at play. Is Project and Note an aggregate? This question stems from another question I have: if there are no invariants to protect, is grouping objects inside aggregates unnecessary?
