Format
X-platform can support various types of data used in almost all industries.
Data Structure
Data on the platform will be processed and stored in a form similar to a table.
A data source (similar to a table) contains several different types of data (similar to different fields in a table), which are usually related or have some commonality and are placed within the same data source.
As an example, a data source can be named "Factory A" and may include several types of data such as temperature, power consumption, motor speed, and duty manager.
The description of each field is as follows：
Data Source Name (English)
It can only contain English letters, numbers, and underscores (_), without spaces. This name will be displayed and used in the URL of the REST APIs, and is also a part of the topic name (second level) in MQTT.
Description
This is for the convenience of the user to record more information about this data source or data, for easy understanding in the future or for other users to understand.
Display Name
This name will be displayed on the charts in the dashboard and in the content of notification events.
