Device ID

An identifier that uniquely identifies a device.

Device Library

An Oracle IoT Cloud Service Client Software Library used to develop Device Applications that communicate with Oracle IoT Cloud Service. Device Libraries are typically used to expose device functionality to Oracle IoT Cloud Service.

Device Metadata

A set of attribute/value pairs that describe an entry in the device repository.

Device Model

Describes the device metadata, message formats, and resources associated with a specific type of device. A device may support multiple device models.

Device Model Repository

The set of Device Models that have been loaded into and are known by an instance of Oracle IoT Cloud Service

Device Selection Group

Logical grouping of devices based on common parameters, such as device model, location, and manufacturer, that are associated with an IoT Application

Device Software

Applications, device adapters, and other software packaged as OSGi bundles that run on the Oracle IoT Cloud Service Gateway, and whose life cycle can be managed through the Oracle IoT Cloud Service Management Console.

Directly Connected Device (DCD)

A device that is capable of communicating directly with Oracle IoT Cloud Service by running an application that uses an Oracle IoT Cloud Service Client Software Library or by calling the Oracle IoT Cloud Service REST APIs.. This device type cannot register any indirectly connected devices. The only supported direct connection protocol is HTTPS over TCP/IP.

Endpoint

An entity that is addressable in the Oracle IoT Cloud Service system. It has a unique ID and can be communicated with using a controlled security policy.

Endpoint ID

The globally unique identifier used to reference a specific Endpoint.

Endpoint Lifecycle

The set of state changes that occur for an endpoint in Oracle IoT Cloud Service. Supported lifecycle states are Registered, Activated, Deactivated, and Decommissioned.

Endpoint Repository

A database that contains information about all the endpoints known to Oracle IoT Cloud Service. The database is internal to Oracle IoT Cloud Service and accessible via Oracle IoT Cloud Service REST APIs requests.

Endpoint State

The operational state of an endpoint in Oracle IoT Cloud Service. The endpoint state determines whether an endpoint can actively participate in Oracle IoT Cloud Service.

Enterprise Library

A Client Software Library used to develop Enterprise Applications that communicate with IoT Cloud Service. Enterprise Libraries are typically used to inspect and control a Device.

Enterprise Application

A software component created for a specific business problem and runs externally to Oracle IoT Cloud Service. It integrates and communicates with Oracle IoT Cloud Service using one of the Oracle IoT Cloud Service connectors or by invoking Oracle IoT Cloud Service REST API.

Enterprise Application Integration

The configuration required to connect streams of incoming data with an Enterprise Application.

Gateway Device

A device that communicates with Oracle IoT Cloud Service on behalf of other devices that are incapable of direct communication with Oracle IoT Cloud Service.

IoT Application

A set of Oracle IoT Cloud Service definitions that comprise an end-to-end IoT solution. These definitions include Device Models, Explorations, and Integrations.

Indirectly Connected Device (ICD)

A device that communicates with Oracle IoT Cloud Service through a Gateway Device. These devices communicate with the Gateway Device over a non-HTTPS TCP/IP protocol or interface, such as Bluetooth, Zigbee, I2C, or GPIO. For this device to indirectly communicate with Oracle IoT Cloud Service, it is required to be connected to a Gateway Device that has already been activated with Oracle IoT Cloud Service.

Integration

The association of an incoming data stream with a data sink. The data sink may be an integrated analytics tool, such as Oracle Stream Explorer, or an external enterprise application, or PaaS. Oracle BI Cloud Service is an example of a pre-defined PaaS integration. Integrations may also contain Annotations.

Log Message

An Oracle IoT Cloud Service Message type used to transmit application or device logging information to the Oracle IoT Cloud Service.

Managed Device

A device configured with the software that supports secure bi-directional messaging, and remote provisioning and lifecycle management of applications from Oracle IoT Cloud Service. This device is configured with the installation of the Oracle IoT Cloud Service Gateway.

Management Console

The web-based user interface (UI) component of Oracle IoT Cloud Service. It is used for performing management and configuration tasks.

Message

A single unit of data stream at a given point in time. It may be any one of the valid Message Types. The payload of a message is dependent on the message type.

Message Format

Specifies a set of key-value pairs of data that are included in an Oracle IoT Cloud Service Message payload. Each Message Format must have a unique identifier using a Uniform Resource Name (URN) value.

Message Type

The specific class of an Oracle IoT Cloud Service Message. The type of the message may be: Data, Alert or Log. The message type dictates the content of the message payload field.

A person who views data and reports generated by Oracle IoT Cloud Service. This person uses either the Management Console or external applications integrated with Oracle IoT Cloud Service.

Shared Secret

A symmetric key that is required to be available on both the device and Oracle IoT Cloud Service for a successful device activation. The shared secret can be created automatically by Oracle IoT Cloud Service during the registration process or provided by the device or the service administrator.
