CoreLAKE - An Out-Of-The-Box Data Lake Platform

CoreLAKE is an out-of-the-box data lake platform to enable healthcare organizations to realize data integrations, data interoperability, data standardization and distribution in a SMART on FHIR format, any EDI format or via an API or file. CoreLAKE has the capability to acquire data from varied sources (like DB, Files, HL7, CCD, EDI, API), ingest data in any format and map to a FHIR model without writing any additional code. The platform has an inbuilt capability to derive golden records for providers, patients and members. It also acts as a data exchange platform where data can be consumed from clinical devices and made available for clinical and decision-support systems to consume in a FHIR format. Apart from being an interoperability solution, CoreLAKE has an integrated data quality and data validation engine with hundreds of preconfigured business quality rules in order to avoid any data discrepancies and lead to wrong decisions or actions. 
This platform has been utilized by a number of providers to help them acquire data from varied sources like Epic (using App Orchid), Cerner hub, HIEs and individual practices, standardize to a FHIR format and make it available for analytics teams to run their models.
