What is Dataplex and how does it differ from Data Catalog?

Dataplex is unified data management for data lakes/lakehouses - organizes data into domains, manages security, quality, metadata. Data Catalog is discovery and metadata service integrated in Dataplex.

How to implement data mesh with Dataplex?

Dataplex Lakes and Zones map to data domains. Each domain has its own policies, security, quality rules. Central governance via organization-level policies.

What is data lineage and how to track it in GCP?

Lineage tracks data flow from source to consumption. Data Catalog automatically captures lineage from BigQuery, Dataflow, Composer. Visualization in Console.

How to set up data quality in Dataplex?

Dataplex Data Quality allows defining rules (completeness, uniqueness, validity), automatically validates them, generates quality scores and alerts on failures.

What are policy tags and how to use them?

Policy tags define data classification (PII, confidential, public). Applied to BigQuery columns, control access via IAM. Automatic sensitive data detection via DLP.

How to organize metadata in Data Catalog?

Entry groups for logical organization, custom metadata templates for business context, tags for searchability, starred items for quick access.

How to ensure GDPR compliance in GCP?

Data Catalog for PII inventory, policy tags for access control, DLP for detection, retention policies, Assured Workloads for EU data residency, audit logging.

What is data stewardship and how to implement it?

Data stewards are responsible for data quality and governance in their domain. Assignment via IAM roles, policy definition in Dataplex, quality dashboard monitoring.

How to automate data classification?

Cloud DLP automatically scans and classifies sensitive data. Integration with Data Catalog for automatic tagging. Scheduled scans for continuous classification.

How to measure data governance maturity?

KPIs: data quality scores, catalogued assets %, lineage coverage, policy compliance rate, time to access data. Dataplex dashboards for visibility.

How to integrate governance across multi-cloud?

Dataplex supports external data sources (AWS S3, Azure). Unified governance policies, central Data Catalog, cross-cloud lineage visualization.
