Overview

A data table is used to store and display telemetry data from devices that have been grouped according to assigned labels (common characteristics such as a business process or a location).

In the Data Tables page, you can view a list of all data tables, with some tables created automatically by thingsHub and some tables created manually by users. These lists only provide basic information. However, by clicking the table’s Edit button you can view detailed information, including all device telemetry data received since the table was implemented.

When we refer to data tables in this document, we will mostly refer to user-created data tables.
