Vibe Coding a BW/4 Migration to a Spark Lakehouse with Delta Tables

Covers:

  • What vibe coding is and why it works for migrations
  • BW/4 data model recap: InfoObjects, ADSOs, star schema abstraction
  • The three-table architecture of ADSOs (inbound, active, change log)
  • ADSO change log vs Delta Table Change Data Feed
  • Extracting transformation logic from BW system tables (RSTRAN, RSTRANFIELD, etc.)
  • The vibe coding workflow: extract → prompt → generate → review
  • Complete mapping table: BW concepts → Lakehouse equivalents

References earlier posts on BW data dictionary analysis.
