Solution BI M2P is a modern data lakehouse architecture ingesting Excel, Benchmark, MAC, and PLOC files into MinIO object storage, then orchestrating extraction and normalization via Apache Airflow and Python scripts. Raw data flows through PostgreSQL staging tables, undergoes dbt transformations with data quality tests, and materializes into a dimensional data warehouse with conformed dimensions and fact tables. Power BI dashboards consume analytical views and machine learning forecasting outputs to deliver KPI visualizations for business users and decision makers. This architecture demonstrates enterprise-grade data governance, traceability via MD5 checksums, and separation of concerns across eight layers from ingestion to analytics.
