BDL Delivery Lifecycle ER diagram models the complete journey from business requirements through production deployment, spanning requirements, specifications, metadata, development tasks, testing, and release management. Data flows from BUSINESS_REQUIREMENT through FUNCTIONAL_SPECIFICATION and METADATA_OBJECT, branching into parallel JIRA_STORY and DEVELOPMENT_TASK workflows, converging at TESTING_UAT and RELEASE before final PRODUCTION_BDL deployment. This schema enforces traceability and governance across the entire BDL delivery chain, ensuring every production object links back to its originating requirement and captures lineage through DATA_LINEAGE relationships.
