Feature (machine learning): A variable in a machine learning problem that can influence the value of the target column, recognized as columns in a dataset within Qlik AutoML. Features are input variables used to make predictions.

Field: Contains values loaded from a data source, corresponding to a column in a table and used to create dimensions and measures in visualizations. Fields represent individual data attributes.

Full load: Refers to the initial replication of data from the data source to the landing in Qlik Cloud Data Integration. It involves transferring all data without incremental updates.

Sheet: A sheet in Qlik Sense is a canvas where you can create a customized view of your data, arranged in a way that tells a story or answers specific questions. Sheets are used for data visualization and analysis.

Sheet objects: Components used to create an interface on a sheet, which can include data visualizations like tables and charts, as well as other objects such as buttons and text objects. Sheet objects are elements placed on sheets for interaction.

Snapshot: Graphical representations of a visualization at a certain point in time, used to create stories. Snapshots capture the state of visualizations for storytelling purposes.

Space data: Governed areas of the Qlik Cloud tenant used to create and store data projects, manage new data connections, and access Data Movement gateways. Space data is where data integration and management activities occur.

Space managed: Controlled spaces used to share apps with a limited group of users. Managed spaces provide a controlled environment for collaborative app development.

Space personal: A private space belonging to users where they can develop apps. Personal spaces are individual workspaces for app development.

Space shared: Areas where apps and data sources can be shared with other users for collaborative development. Shared spaces facilitate teamwork and sharing of resources.

Storage: Part of the data pipeline containing ready-to-consume datasets in Qlik Cloud from data copied from the landing zone. Storage is where data is stored and made available for analysis.

Story: A tool that allows the sharing of data insights and discoveries made in an app with other users, combining reporting, presentation, and exploratory analysis. Stories enable data-driven narratives.

Subscription: Reports that let you schedule recurring emails containing a PDF of selected sheets or charts. Subscriptions automate the delivery of data insights to users.

Synthetic key: A composite key between two tables in the data model, created when two or more tables have common fields, which may need to be reviewed if it results in a data model error. Synthetic keys are generated to link related tables.

Tables: ODS, HDS, and Change: Types of tables in a data project such as the Current table (ODS), the Prior table (HDS), and the Change table, serving different purposes within the data architecture. These tables are used to manage historical data changes.

Target: The destination or endpoint where data is intended to be transferred, stored, or loaded, in data movement, migration, or synchronization processes. Targets define where data should be placed.

Tenant: The deployment of Qlik Cloud, holding items such as users, apps, and spaces. Tenants represent the individual environments within Qlik Cloud.

Training dataset: The dataset used to train a machine learning model in Qlik AutoML, designed to learn patterns and make predictions on new data. Training datasets are used to teach models.

Transform: A task that allows creation of reusable data transformations in a data pipeline with rules and custom SQL. Transformations modify data to prepare it for analysis or storage.

Type 1 - Operational Data Store (ODS): In ODS datasets, new information overwrites the original information, i.e., no historical data is kept. Type 1 ODS tables update existing data with new information.

Type 2 - Historical Data Store (HDS): In HDS datasets, a new record representing the new information is added to the table, including both the original and the new record. Type 2 HDS tables maintain historical data.
