Biz

The Use Cases in biz are basically pass-through calls to the data layer.

The models in these packages are internal to inventory-api. If the system uses an ORM like gorm, they are the structs that are annotated to reflect database table mappings.

A user request initially creates objects from the public api layer. The service layer transforms them into models from biz. The reverse happens for responses: the service layer translates biz models to public api objects.

The eventing subsystem also has a relatively simple model in its api package, and the data subsystem translates biz models to it before sending events.
