D.Hub at a glance — the map of five surfaces
A one-line tour of Collection, Pipeline, Ontology, Dashboard, and Agent—and where each journey begins in the portal.
5 min
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.
What you should be able to do after this lesson
- Name the five surfaces (Collection · Pipeline · Ontology · Dashboard · Agent) and what each answers
- Recall the global search shortcut and where the home screen sits
