This glossary highlights some of the key terms that will help you get familiar with and understand Decision Insight better . For some terms, click the available link to get more detailed information. 

Architecture concepts

Term Definition
Deployment A complete installation of Decision Insight (DI) where DI is up and running. For more information, see Deployment architectures.
Standalone installation Installation of the deployment as a single instance of DI deployed on a single node. For more information, see Standalone deployment.
Clustered installation Installation of the deployment as one cluster or a set of clusters. Clusters may have a functional role or a technical role or both. For more information, see Clustered deployment.
Cluster ID The cluster ID uniquely identifies clusters within your deployment. All nodes within a cluster should have the same cluster ID. A cluster ID a 64-bit identifier that is represented with 3 groups of hex digits for human readability (for example, xxxxxxxx-xxxx-xxxx where x are hexadecimal digits).
Configuration file A configuration file contains information about file settings and file changes in your node directory. You can use configuration files to apply several node settings to one node all in one command line.  For more information, see Configure a node.

Time concepts

Term Definition
Observation mode The way you observe data on your dashboard using the time machine. you can observe data at a given instant or see how it evolves over an interval of time.
Rhythm A rhythm is an increment of time used to define the granularity of time within an application and within components of the application.
Transaction time (TT) The time when the deployment is aware of a given piece of data. This is used mostly for monitoring and past data management.
Valid time (VT) The time related to a piece of data, that is the basic monitoring time axis.

Application concepts

Term Definition
Application The top-level structure in your deployment. Applications are used to organize your data. An application comprises a set of dashboards, along with the underlying model, computed attributes, and data integration elements.
Application version Application versions are a means of managing the configuration history of an application. All versions can be exported, so you can easily retrieve past application versions.
Space Spaces act like containers to hold definitions that describe your solution.

Design concepts

Term Definition
Attribute An attribute is an element that holds a value of a supported DataType.
Baseline An initial collection of data on a given period and used as a basis for data comparison.

Entities are the central element of the model. An entity centralizes a set of attributes and is similar to a class  in an object-oriented language.

Entity key

Once you've defined attributes for an entity, you can specify that one or more of these attributes will be entity keys. Keys are used to identify, retrieve, and solve instances of data during the data integration process.

Instance Each object in a given entity is called an instance.

A calendar is an advanced feature that enables you to define attributes whose value changes according to configured rules.

Model The model is the data model of the monitored process in the deployment. The data model is the central component that describes what information is available for the application.

Catchup occurs at node restart. It's the period of time during which DI progressively catches up on all the key performance indicators (KPIs) it could not compute while the node was stopped.  

Data integration concepts

Term Definition

Mappings enable you to map data to Entities and Attributes .

Route Routes describe the path between the customer data and the model, entities, and attributes defined in the deployment. It can also send data to external system.
Trigger Triggers enable you to react to the creation/update/deletion of an entity instance.

Alerting concepts

Term Definition
Notification Notifications enables you to create alerts when the status of a KPI reaches a critical state.
Notifier Notifiers allows notifications to send alerts to the outside world.
