6 weeks Cohort Advanced
Overview
When two teams share a database by accident, integrations rot. This module has you publish curated integration events, translate between ubiquitous languages, and document upstream/downstream SLAs with testable stubs. Case studies come from inventory and fulfillment handoffs rather than toy e-commerce.
