Data broker

The data broker functionality is an optional feature in Enterprise tenants which lets you share data selectively with other tenants.

For details see Platform administration > Using the data broker.

Data explorer

Part of the Cockpit application. The data explorer visualizes all data points (that is, measurements or sensor data) of either a particular asset or of all assets.

For details see Application enablement & solutions > Cockpit > Data explorer.

Data lake

Used in the context of DataHub.

A data lake serves as a storage container for offloaded data either on the basis of ADLS Gen2/Azure Storage (Azure), S3 (Amazon), NAS, or HDFS.

Data point library

The Data point library provides a collection of data points with default values for data point properties which serve as templates that can be applied easily to your data points from different devices.

For details see Application enablement & solutions > Cockpit > Data point library.

Device

Devices are a special type of asset. They can constitute a hierarchy of devices. In the Cumulocity IoT inventory their digital twins are represented as managed objects.

Device Management application

The Device Management application is one of the default applications of Cumulocity IoT. The Device Management application provides functionalities for connecting, managing and monitoring devices and allows to control and troubleshoot devices remotely.

For details see Device management > Device management application.

Device protocol

A device protocol defines how data from a specific device type should be transferred into the Cumulocity IoT platform. It contains protocol-specific information about where the data is obtained from, how to transform it, and how to store it in Cumulocity IoT. The definition of the device protocol differs based on the underlying protocol used by the device (for example, Modbus, LoRa, OPC UA or LWM2M).

For details see Device management > Protocol integration.

Digital twin

A digital twin is a digital representation of physical or virtual assets. Devices, sensors and tools are examples of physical assets, virtual assets can for example be processes or rules. In Cumulocity IoT they are represented as managed objects.
