Catalog Overview

The Matia catalog is the central place to discover and govern data assets — everything connected to your environment: data warehouses, databases, schemas, tables, ETL and reverse ETL sources and destinations, BI integrations, and orchestration tools (e.g. dbt). You browse and search assets, view metadata, assign tags and owners, apply certificates, and explore lineage.

What the Catalog Contains

• Data warehouse: Connected warehouses (e.g. Snowflake, BigQuery, Databricks) and their databases, schemas, and tables.
• Sources and destinations: Assets used by ETL and reverse ETL integrations (Postgres, Salesforce, HubSpot, etc.).
• BI integrations: e.g. Tableau, Metabase, Omni.
• Orchestration: e.g. dbt instances.

You add assets via Add Asset (Catalog → Add Asset → Add a source / destination / warehouse / BI integration / dbt). The same assets can be used when creating integrations so you do not connect the same system twice.

Catalog Homepage and Asset Tree

The Catalog sidebar item opens the catalog homepage. On the left, the asset tree shows the hierarchy of connected assets. Click an asset to open its details in the content area: Overview (contents, description, owners, tags), Usage (where supported), and Lineage (for tables). The right sidebar shows freshness, row count, custom monitors, schema changes, description, owners, tags, and certificates.

How Catalog Fits with the Rest of Matia

• Integrations: When you create an ETL or reverse ETL integration, you select source and destination from existing assets or connect new ones. New connections appear in the catalog.
• Observability: Monitors are attached to warehouse tables/columns. You can add custom monitors from the catalog (+ under monitors on a table/column). Schema enable/disable for auto-monitors uses warehouse schemas visible in the catalog.
• Lineage: For tables, the Lineage tab shows upstream and downstream flow (warehouse, dbt, Matia integrations, BI). Lineage is built from catalog metadata and integration metadata.
• Governance: Tags, owners, certificates (Verified, Draft, Deprecated), and announcements (Information, Warning, Issue) are set on catalog assets and surface in search and details.
