domain-modeling

Domain modeling for ScalarDB involves identifying bounded contexts, aggregates, entities, and value objects while aligning transaction boundaries with hexagonal architecture. This process ensures ubiquitous language and repository boundaries map correctly to ScalarDB managed and non-managed tables.

Strategic domain-driven design defines bounded contexts, context maps, and ubiquitous language, while tactical domain-driven design implements value objects, entities, aggregates, domain services, and domain events. Both layers are integrated with hexagonal architecture and ScalarDB transaction boundaries.

Hexagonal architecture integrates with ScalarDB by isolating domain logic from persistence concerns. Repository boundaries and data persistence patterns are designed to respect ScalarDB transaction boundaries, ensuring consistent aggregate operations across managed and non-managed tables.

Defining aggregates and value objects within a bounded context requires establishing a ubiquitous language and mapping domain events. Tactical design patterns structure entities and domain services while maintaining consistency boundaries for ScalarDB persistence operations.

ScalarDB managed tables handle transaction boundaries directly, while non-managed tables require external coordination. Domain modeling maps repository boundaries and persistence patterns to these table types, ensuring aggregate consistency within the hexagonal architecture.

Domain events should be used when state changes within aggregates need to propagate across bounded contexts. They decouple subsystems within the hexagonal architecture and maintain data consistency across ScalarDB transaction boundaries.
