We are planning to develop a EHR/Billing Software and we are aware about HIPAA rules and regulations. Our current application architecture using a shared database with all client's(Provider/Practice) data. I would like to know if HIPAA recommends in isolating database per client(Provider/Practice). Single database for every client. Is it a security breach to HIPAA rules and regulations in data security?

Thanks ~Arun
