The Data Hub is your central location for managing all data connections in AstroBee. Upload files, connect external tools, and explore your data before building a data layer.

​
File Uploads

Upload spreadsheets directly: Drag and drop files or click to browse.

​
External Connectors

Connect business tools via secure Fivetran integration:
External connections use Fivetran, a SOC 2 certified data integration platform. Your credentials are encrypted and never stored by AstroBee.

​
Data Source Cards

Each connected source shows a card with key information:

​
Exploring Tables

Click a table name to preview its data:
Table preview

Table preview showing data and schema

The preview shows:
  • Column names with data types
  • Sample data (up to 20 rows)
  • Pattern analysis buttons for each column

​
Pattern Analysis

AstroBee automatically analyzes columns to discover patterns:
Pattern analysis

Pattern analysis for Customer ID column

Pattern details include:
  • Description — Human-readable pattern explanation
  • Coverage — Percentage of values matching the pattern
  • Regex — Technical pattern definition
  • Examples — Sample values matching the pattern
Patterns help AstroBee:
  • Understand data semantics (IDs, emails, dates)
  • Suggest appropriate entity mappings
  • Discover relationships between tables

​
Linkage Discovery

AstroBee automatically discovers relationships between tables within a data source:
  • Key references — Foreign key relationships (e.g., orders.customer_id → customers.customer_id)
  • Pattern matches — Columns with matching patterns across tables
View discovered linkages in the Data Layer → Linkages tab.

​
Managing Data Sources

​
Renaming

Click the data source name to rename it. Names help identify sources when connecting to data layers.

​
Syncing

External connectors sync automatically based on your Fivetran configuration. File uploads are one-time imports. To update file data:
  1. Upload a new version of the file
  2. The existing source is replaced

​
Deleting

Click the menu button (⋮) on a data source card to delete it.
Deleting a data source removes its data from AstroBee. Data layers using this source will lose access to its tables.

​
Demo Data

New accounts can load demo datasets to explore AstroBee: Demo data is great for learning the platform before connecting your own data.
