HL7 FHIR R4 Data Structure: Overview of the StorageJson Class

Details

This document describes the Java code and interface implementation details of the `StorageJson` class, which is part of the HL7 FHIR resource structure. The class aims to handle JSON formatted data through interaction with a data store (Store). Key functionalities include methods related to database operations such as adding rows (`addRow`), creating stores (`createStore`), and finishing processes (`finish`). Furthermore, it provides validation methods for structural checks of the data, such as retrieving JSON arrays (`getRows`), checking array support (`supportsArrays`), and verifying complex type support (`supportsComplexTypes`). These functions are utilized in FHIR systems to flexibly store and manage resource data in JSON format, maintaining data integrity between the database layer and the application layer. This serves as an important technical reference for understanding the mechanism of data persistence in the backend of healthcare information systems.
