An introductory overview of Hanami's database layer, explaining its three core components: Relations (schema and datasets), Repos (repository pattern abstraction), and Structs (immutable object representations). The author notes that Hanami deliberately avoids a traditional Rails-style model layer in favor of this more modular ROM-based architecture.
Background
Hanami is a Ruby web framework known for its modular design and separation of concerns, using ROM (Relations Object Mapper) as its database layer instead of an Active Record-style model layer.
