Aggregate root is a meaningful object in the domain. It can be viewed as a write boundary for entities and value objects that will maintain write consistency.
Usually it represents a single table, but can span several tables and can be used like document or similar data structure. Since every aggregate is also an entity, it has a unique identification represented by its URI.
DSL example:
module Todo { aggregate Task { Timestamp startedAt; Timestamp? finishedAt; Int? priority; Seq<Note> notes; } value Note { Date entered; String remark; } }
