D.Hub at a glance — the map of five surfaces
What you will learn
A one-line tour of Collection, Pipeline, Ontology, Dashboard, and Agent—and where each journey begins in the portal.
D.Hub has five core surfaces: Collection · Pipeline · Ontology · Dashboard · Agent. The sidebar provides direct entries for Collection, Pipeline, Dashboard, and Agent. Ontology is a section with two entries: Modeling and Graph Explorer. This lesson explains what each surface answers, in one line.
The five surfaces in one table
| Surface | The question it answers | What it produces |
|---|---|---|
| Collection | "What data do I have, and where is it?" | A workspace grouping assets such as datasets, sources, views, code, pipelines, knowledge, dashboards, and collection-scoped agents |
| Pipeline | "How do I automatically derive a processed result from raw data?" | Code-node chains, scheduled runs |
| Ontology | "How does my data fold into a conceptual model as a graph?" | Entities + relations + graph instances |
| Dashboard | "How do I show results to a person on one screen?" | Combinations of widgets (KPI · charts · tables · maps) |
| Agent | "How do I automatically route natural-language input through tools and decisions?" | One cycle of tools + actors + LLM |
The five depend on each other. A collection holds the data, a pipeline processes it, the ontology binds it into a graph, the dashboard shows it, and an agent pulls it back via natural language.
Two entry points beyond the sidebar
Two other entry points come up often.
- Global search — From anywhere, press ⌘KCtrl+K⌘K / Ctrl+K to search resource names · tags · body content at once. The fastest path when you can't recall an exact name.
- Home — Search for resources and review Recent Items, Data Assets, and What's New. Start the AI Assistant from the button in the page header, wherever you are in the portal.
