Primitive Structure Type

The PrimitiveStructureType is an essential part of the StructureSchema package in stapi.ai's Core, which forms the building blocks for Domain-Driven Design (DDD) business logic modeling in a declarative way. It encapsulates primitive data types as defined in the FHIR StructureDefinition.

FHIR Connection and Domain-Driven Design

In FHIR, primitive types are the basic building blocks of data, representing simple data like integers, strings, booleans, etc. Similarly, in stapi.ai, PrimitiveStructureType represents these elementary data types. The characteristics of these types in FHIR, such as their constraints or behavior, are faithfully reproduced in the stapi.ai Core.

From a DDD perspective, PrimitiveStructureType can be likened to the basic building blocks that make up more complex Value Objects and Entities. Just like in any domain model, the primitive types provide the fundamental data that the more complex types are composed of.

Role in Declarative Programming

The PrimitiveStructureType plays a foundational role in declarative programming as part of stapi.ai Core. By defining these elementary data types, stapi.ai provides the 'what' of the system—declaring the types of data the system can handle. The actual handling ('how') is taken care of by the underlying system itself.

By reflecting FHIR's primitive types in its structure, PrimitiveStructureType allows users to express their healthcare system's data needs using standardized, interoperable data models. This alignment with FHIR not only simplifies the process of implementing healthcare IT systems but also promotes better interoperability and data sharing.

Keep in mind that PrimitiveStructureType is a part of a broader system—the StructureSchema. To gain a comprehensive understanding of the system, explore the other components such as ComplexStructureType and FieldDefinition.
