Historian introduction and overview
The world is being flooded with sensors. We are measuring more parameters for longer periods than ever before, piling up huge amounts of data. Big data becomes difficult to store, access, and visualize. Especially when it comes to monitoring applications or conducting long-term tests, the challenge is how and where to store the data in order to be easily accessible from anywhere in the world at any time.
Historian enables reliable data transfer from multiple Measurement Units into a time-series database that can be hosted on a custom private server or in a cloud. The data stored in the database can be accessed through a web browser on any device (desktop, tablet, mobile) or an instance of DewesoftX software.
The Dewesoft measurement units run an instance of DewesoftX software. They communicate via the MQTT protocol with the Historian database. On the server side, an MQTT broker temporarily holds the data published by Historian clients running on the Measurement units and serves the data to the Historian client subscribers which can be either a database consumer service or a DewesoftX instance.
Dewesoft Historian brings the data from the most capable DAQ hardware and software on the market into the cloud for historical and worldwide access, keeping core Dewesoft features intact: reliability, usability, and expandability.
