We are planning to use FHIR as our persistence DB for a EMR system that we are building. Is that a good idea or is it better to have our own persistence DB and then ETL the data to FHIR for interoperability? In addition, I have some reporting needs as well and so, is that a good idea to build those reporting needs on top of FHIR DB If I chose to go with FHIR as my persistence DB?

Upon some PoCs, we see that FHIR DB is taking more time to store the data and does not seem to have been designed to support persistence applications but more to support interoperability? Is my understanding correct?

Thank you.
