The i4Q Data Repository (i4QDR) is a distributed storage system that will oversee receiving, storing, and serving the data in an appropriate way to other solutions. This solution is suitable to support and enhance a high degree of digitization in companies with most manufacturing devices acting as sensors or actuators and generating vast amounts of data. The i4Q Data Repository (i4QDR) is aimed at providing, in a centralised fashion, the functionality related to the storage of data in the whole i4Q system. Indeed, the i4QDR is involved in all the pilots and is expected to interoperate with a large subset of the i4Q solutions.
