Pushing the envelope of our understanding of the universe requires physics experiments that measure and analyze data from many disparate systems. Such systems generally have widely different requirements and architectures, making it difficult to implement a single, monolithic program for control and readout. CouchDB is an optimal tool to integrate and save data from such systems since its RESTful interface provides a minimal hurdle that almost all devices large and small can achieve. In this presentation, Mike Marino will describe how CouchDB is being used in the nEDM experiment at the Technische Universität München to integrate, control, view and save measurement data from many different subsystems, ranging from those powered by microcontrollers and mini PCs (Arduinos and Raspberry Pis) to those based on the industrial VMEbus.
