Australian Retailer Catalogs 1,600+ Undocumented Tables in 3 Days Using AI-Powered Metadata Intelligence
Post-acquisition MySQL to BigQuery migration accelerated from months to days through automated metadata discovery and domain analysis.
Challenge
Zero documentation on acquired company's 8 MySQL databases with 1,600+ tables and 24,000+ columns blocking BigQuery migration timeline.
Solution
3X Metadata Intelligence Engine automatically cataloged complete estate, generated comprehensive metadata canvas, and delivered domain and KPI analysis in under 3 days.
Results
Complete metadata catalog delivered in 3 days vs 8-12 week manual estimate- 1,600+ tables and 24,000+ columns documented with object-level granularity- Data domain analysis and KPI recommendations completed in hours- Migration planning unblocked, enabling BigQuery deployment to proceed on schedule- Estimated savings: 10+ weeks of manual analysis effort eliminated.
Client's Problem Statement
A leading Australian retailer acquired a regional competitor and needed to consolidate 8 MySQL databases into their Google BigQuery analytics platform. The acquired company had virtually zero documentation on their datasets-no data dictionaries, no schema descriptions, no business context, and no understanding of data domains or relationships across the 1,600+ tables and 24,000+ columns. The retailer's data engineering team faced a critical bottleneck: they couldn't design the BigQuery target architecture, plan the migration, or establish data governance without first understanding what data existed, how it was structured, and what it represented. Manual analysis would require 8-12 weeks of interviewing subject matter experts (many no longer with the company), reverse-engineering schemas, and documenting business logic-delaying the entire migration program and putting business integration timelines at risk.
Our Solution Approach
- Rapid automated discovery connecting directly to all 8 MySQL databases with read-only access to extract complete schema metadata, data samples, and relationship patterns
- AI-powered metadata inference analyzing table names, column names, data types, and data patterns to generate semantic descriptions and business context automatically
- Comprehensive metadata canvas delivering object-level documentation including table purposes, column definitions, data types, constraints, relationships, and sample values
- Intelligent domain analysis classifying tables and columns into business domains (customers, orders, products, inventory, finance) using graph-based reasoning and pattern recognition
- KPI and analytics insights identifying potential key performance indicators, aggregation opportunities, and analytical use cases based on data structure and content analysis
How We Implemented
- Day 1 (Setup & Connection): Configured read-only connections to all 8 MySQL databases, validated access, defined scope (all tables and schemas), and initiated automated metadata extraction processing
- Day 2 (Processing & Analysis): 3X Metadata Intelligence Engine processed 1,600+ tables and 24,000+ columns, performed semantic inference, generated business context, and built relationship maps automatically
- Day 3 (Delivery & Review): Delivered comprehensive metadata canvas with complete data dictionary, domain classifications, lineage maps, and initial findings; conducted review session with client data team
- Day 3 (Enhanced Analysis): Client requested additional domain analysis and KPI recommendations; accelerator reprocessed with enhanced parameters and delivered detailed domain mapping and 50+ potential KPIs within 2 hours
- Handoff & Enablement: Provided metadata catalog exports (Excel, JSON, SQL,HTML), trained client team on navigating and updating the canvas, and enabled self-service metadata queries for ongoing use
Conclusion
By leveraging 3X Metadata Intelligence Engine, the Australian retailer transformed an 8-12 week manual documentation challenge into a 3-day automated discovery engagement. The comprehensive metadata canvas with object-level granularity provided the foundation for confident BigQuery architecture design, migration planning, and data governance implementation. Additional domain analysis and KPI insights delivered in hours (not weeks) enabled business stakeholders to understand analytical opportunities within the acquired data assets immediately. The accelerator eliminated the migration bottleneck, compressed planning timelines by over 90%, and provided a permanent metadata asset the team continues to use for ongoing data management. Most importantly, the retailer's data engineering team gained detailed understanding of the acquired estate without dependency on subject matter experts who were no longer available, de-risking the entire integration program.
