The series finale: a caveated head-to-head — Iceberg vs. Delta, Presto C++/Velox vs. Photon, IBM Knowledge Catalog vs. Unity Catalog, Milvus/OpenRAG vs. Databricks vector search — plus how IKC and Apache Ranger govern Maximo-derived data, LABTRANS PII masking, and watsonx.governance lineage.

Four real ways to extract MAS 9 data for a Databricks lakehouse — REST/JSON API, MIF over Kafka and the Data Export framework, DB-direct, and Lakehouse Federation — with real object structures, Kafka broker config, and honest CDC framing.

A table-by-table medallion architecture for MAS 9 data — cleansing rules for WORKORDER, ASSET, MATUSETRANS, PM, and meter data, conformed dimensions, and gold marts for reliability and cost analytics.

Worked Databricks SQL for the five gold-layer questions a maintenance leader actually asks: MTBF/MTTR trend health, maintenance cost rollups, slow-moving inventory, work order backlog aging, and PM compliance — built on Part 3's silver and gold tables.

A scored decision framework for choosing between Maximo Predict's prebuilt models and a custom AutoML/MLflow model in Databricks — data needs, in-house ML skills, AppPoints economics, and how to write a score back into Maximo.
