# Data catalog

> Discover, document, and organize your organization's data assets.

The **data catalog** is your searchable inventory of tables, streams, pipelines, and related assets. Teams document purpose, freshness, ownership, and sensitivity so newcomers and adjacent teams stop relying on tribal knowledge.

## Enterprise feature

Full catalog capabilities—automated harvesting from connections, curated business glossary, and team-scoped visibility—ship with **Enterprise** plans. Lower tiers may expose read-only subsets or manual entries only. Ask your admin if harvesting jobs are enabled for your warehouse and lake connections.

## Table discovery

Planasonix can **crawl** connected systems on a schedule you define:

* Schemas, tables, and columns with inferred types
* Row count or profile snapshots where permitted
* Tags suggested from naming patterns (you approve before promotion)

Harvest jobs use read-only credentials. Large estates should scope crawls to approved databases or schemas to control cost.

    Register Snowflake, BigQuery, Redshift, Databricks SQL, and similar endpoints; choose databases to include.

  <Tab title="Lakes">
    Register object storage-backed tables (Iceberg, Delta, Hive metastore) when connectors support metadata extraction.
  </Tab>

  <Tab title="Applications">
    Some SaaS connectors expose object metadata for documentation even when you do not ingest the data yet.

## Search

Use **keyword search** across names, descriptions, column names, and tags. Filters narrow by domain, owner, freshness, certification status, or sensitivity. Save frequent searches for onboarding checklists.

<Tip>
  Standardize tags (`domain:finance`, `pii:email`) early so search stays usable as the catalog grows.
</Tip>

## Documentation

Each asset supports **markdown descriptions**, **column-level notes**, and links to runbooks or dbt model pages. Certified assets display a badge when stewards approve accuracy.
