This video is part of the Databricks Lakeflow Masterclass, a series designed to teach modern Lakehouse architecture, data pipelines, governance, and reliability patterns using Databricks.

In this session, we explore Data Contracts — one of the most important practices for building reliable, scalable data pipelines.

Many data teams struggle with:

• breaking schema changes
• poor data quality
• unclear ownership
• unreliable data delivery

Data contracts solve these problems by creating a clear agreement between data producers and consumers.

A data contract defines:

• Schema – structure and data types
• Quality rules – validation expectations
• SLAs – freshness and availability guarantees
• Semantics – business meaning of data

This approach ensures pipelines remain stable, trustworthy, and production-ready.

In this video you will learn:

• What data contracts are and why they matter
• Common problems caused by missing contracts
• How data contracts prevent breaking pipeline changes
• A real-world example using a student enrollment dataset
• How to enforce contracts using Databricks Expectations
• How data contracts improve data quality, reliability, and trust

By the end of this session, you will understand how to implement data contracts in a Lakehouse architecture to ensure your data pipelines remain AI-ready, business-ready, and decision-ready.
