3X REVERSE ENGINEER
Reverse Engineer
Legacy Systems
in Hours.
Migrating legacy OLTP, OLAP, and ETL systems without complete system understanding leads to costly rework, missed dependencies, and stalled modernization timelines. 3X Reverse Engineer automatically deconstructs complex legacy databases and ETL pipelines, generating enterprise-grade documentation that captures every table, dependency, and business rule.

Problems we solve
Every delayed migration traces back to the same root causes: undocumented systems, tribal knowledge, and manual discovery that takes months before real work begins. 3X Reverse Engineer eliminates them systematically.
Undocumented Legacy Systems
Decades-old Teradata, Oracle, SQL Server, and mainframe systems with no schema docs, no data dictionaries, and no clear starting point for cloud migration planning. Teams inherit complexity they can't see.
Tribal Knowledge at Risk
Business logic and transformation rules live only in SMEs' heads. When they leave or get stretched thin, institutional knowledge disappears for good.
Months of Manual Discovery
3 to 6 months tracing schemas, stored procedures, ETL dependencies, and cross-system data flows before real migration work begins. Discovery becomes the bottleneck.
No Functional Documentation for Conversion
Without documented business logic and data lineage, accurate conversion is guesswork. Logic gaps surface in production, not during planning.
Hidden Compliance and Data Risk
Unknown PII, undocumented quality rules, and missing lineage create GDPR, HIPAA, and SOX risks. Auditors ask questions teams can't answer.
Inaccurate Effort and Cost Estimates
Without automated complexity scoring, budgets are based on assumptions. Projects overrun because true scope shows up mid-flight.
Key features
Six intelligent analysis modules automatically produce enterprise-grade documentation that would take senior architects months to create manually. From schema analysis to compliance reporting, every output is structured, searchable, and ready for migration planning.
Deep System Analysis
Automated examination of schemas, stored procedures, functions, views, triggers, and ETL logic across OLTP, OLAP, and hybrid systems. Captures every object, relationship, and embedded rule.
Executive Summary Generation
Complexity assessment, modernization readiness, risk analysis, cost drivers, and strategic recommendations. Gives CDOs and program leaders the full picture without weeks of discovery.
Functional Documentation
Documents data flows, transformation rules, business processes, and the functional purpose of every object. Captures knowledge that would otherwise leave when SMEs transition or legacy systems are decommissioned.
Technical Specification Extraction
ERD diagrams, dependency maps, data lineage visualizations, integration points, and architectural pattern documentation generated automatically. The blueprint architects need for target-state design.
Object Complexity Scoring
Classifies and scores every database object by complexity, dependency depth, and cross-system references. Sprint planning backed by data, not assumptions.
Data Quality & Governance
Automated PII detection, data quality profiling, compliance gap analysis, and audit-ready governance reports for GDPR, HIPAA, SOX, and industry-specific regulatory requirements. Risks surface before migration begins, not after.
Dependency lineage
3X Reverse Engineer automatically maps the full dependency graph of your legacy system from source tables all the way to downstream consumers.
