Dataset Catalog
The Dataset Catalog lets you browse, inspect, and manage all datasets in your workspace.
Viewing Your Datasets
Navigate to Datasets in the sidebar to see all available datasets.
Each dataset shows:
- Name — the table name in the data warehouse (e.g.,
sales_data,customer_list) - Description — what the dataset contains
- Actions — View details or Delete
System datasets (created by the platform for KPIs and dashboards) are protected and cannot be deleted.
Dataset Detail View
Click View on any dataset to see its full details:
Schema Viewer
The schema table shows every column with:
| Field | Description |
|---|---|
| Column Name | The column identifier |
| Type | Data type (string, number, date, boolean, etc.) |
| Description | Human-readable description of what the column contains |
| PII | Whether the column contains personally identifiable information |
| Key | Whether the column is a primary/business key |
Data Preview
A sample of rows from the dataset is displayed in a scrollable table so you can verify the data looks correct.
Editing Metadata
Click the Edit toggle to modify:
- Dataset description — Update what the dataset contains
- Column descriptions — Add or change descriptions for each column
- PII flags — Mark/unmark columns as containing sensitive data
- Key flags — Designate primary/business key columns
Click Save when done. Updated metadata immediately improves AI accuracy when answering questions about this dataset.
Important: Good column descriptions dramatically improve AI query accuracy. Instead of just "amount", describe it as "Net sale amount in BRL after discounts, excluding taxes".
Linked KPIs
Some datasets are created by the KPI system (e.g., materialized KPI tables). These show a Linked KPIs section listing which KPIs depend on this dataset.
Deleting a Dataset
- Click the Delete button on the dataset row
- Confirm in the dialog
Deleted datasets are permanently removed from the data warehouse. This action cannot be undone.
