Couchbase, a JSON-based database, has emerged as a viable alternative to traditional RDBMS by offering capabilities such as distributed storage, high availability, and cross datacenter replication, while natively storing data in JSON format. It provides a powerful N1QL query language that allows users with SQL experience to efficiently navigate and query data stored in hierarchical JSON structures, making it particularly suitable for implementing the Fast Healthcare Interoperability Resources (FHIR) standard in healthcare applications. FHIR, developed by HL7, facilitates interoperability between different healthcare systems by defining a common framework of resources that represent various aspects of healthcare, from administrative details to clinical functions. Couchbase's JSON storage format and advanced querying capabilities, including document JOINs and processing of embedded array objects, enable healthcare organizations to manage FHIR data efficiently, reducing application complexity and improving performance. The blog highlights the interest from healthcare organizations in using Couchbase to develop FHIR-compliant applications, leveraging its NoSQL advantages to simplify complex data operations and enhance interoperability across multi-cloud environments.
