Episode notes
Data Contract Is Four-Part Agreement
- A data contract is more than schema; it bundles schema, semantics, SLA, and governance into a shared expectation.
- Mike Carlo highlights schema, business rules, refresh SLA, and metadata ownership as the four contract pillars from the Atlan article.
Contracts Are Technical And Cultural
- Data contracts aren't inherently 'technical' — they combine technical schema with nontechnical governance and SLA expectations.
- Mike argues schema is necessary but the trust-building parts (SLA, ownership) make contracts practical for business users.
Semantics Capture Business Rules Not Just Types
- Semantics are the business-level rules and definitions that make data meaningful across teams.
- Examples include defining a customer (last purchase window) or assertions like "this column cannot be null," which enable repeatable tests and trust.
