Qi is a highly flexible cloud-based sequential data historian that is used to store, retrieve, and analyze data. You create and write data to streams using a simple REST API. The streams are able to store simple or complex data types to suit the application needs. An assortment of methods with customizable behaviors are available to read data and easily obtain needed information.
