Explore Data

The Explore Data screen (Discover menu — previously called "Explore Graph") shows, on a visual map, what exists in each context of the platform: the graph entities and relationships, the fields of the search indices and the relational tables — all driven by the sources declared in the context's registration, without writing Cypher or SQL.

Navigating — a 4-level drill-down

1. Root — the DATTA node in the center. Click to discover the contexts.
2. Contexts — click a context to open its data sources.
3. Data sources — each source declared on the context becomes a node, colored by engine: Neo4j (databases, one per origin — e.g. febraban, cvm, base-negativa, bcb, cnpj), OpenSearch (indices) and Trino (schemas). The panel lists the sources with counts (entities, documents, tables); click a source — on the map or in the panel — to open it.
4. Source objects:
   • Neo4j database → the entities and relationships of THAT database, with local counts; an empty database says so.
   • OpenSearch index → the fields on the map and, in the panel, the exact document count and sample data (first documents of the index).
   • Trino schema → the schema's tables; querying the data goes through a JDBC agent (panels) or DATTAX (FROM TRINO).

The breadcrumb (DATTA › Contexts › context › source) and the Back button go up one level at a time.

Where the sources come from

The screen shows exactly what the context declares in Configure › Contexts › Databases (the per-origin dataSources — see Contexts and the public negative list admin guide). A context with a single database keeps working as before (a single source at level 3); a per-origin context shows one source per database/index/schema.

Permissions

• GRAPH_EXPLORE — opens the screen and loads the per-context sources.
• SEARCH_EXECUTE — OpenSearch index fields.
• PANEL_VIEW — Trino schema tables.

Without one of these permissions the corresponding section simply does not appear — the screen never breaks for lack of permission.
