How should developers design Dataverse relationships to support complex enterprise data models without creating unnecessary complexity?

Effective Dataverse architecture begins with a well-designed data model rather than simply creating tables as requirements appear. This discussion examines 1:N, N:1, N:N relationships, lookup design, cascading behavior, ownership, alternate keys, and normalization considerations in enterprise solutions. Developers should understand when a relationship belongs directly in Dataverse and when another architectural pattern is more appropriate. The goal is to help learners design scalable and maintainable Dataverse solutions that remain manageable as applications and data volumes grow.
