## AI overview

This article explains how to handle multi-table inserts in Room when entities have nested dependencies. It first considers separate DAO interfaces and a wrapper class, then shows how interface inheritance can centralize insertion logic and let dependent DAOs reuse it.

## Source excerpt

A properly relational database may have a type that appears referenced multiple times. In my SpaceNerd playground app, that is the Country object. An Agency has a country, and an Agency is a dependency of a Launch, of a Space Station, and likely more types to come. How do I enforce that any time I insert an Agency, I also insert the Countries associated with it? That's what this blog post sets out to explore, and the answer is much simpler than I thought when I started.
