The EKR Orchestra platform rests on very solid foundations given by a back end that rests on various types of databases, such as Postgres Sequel or Sap HANA, using a hybrid database for the structure of extremely granulated information and a nosql database for managing the information, with data search and performance functions.

Everything is exposed through a set of .ekr-api web services and can be used through an on-premise or platform-as-service mode, in cloud mode.
