Forensic SQL process reengineering
[Reengineering · Grupo Diveco]
Redesign of the operation's SQL processes. Up to 90% reduction in execution times (from hours to minutes) for the materials explosion process (MRP), unblocking the complete migration to Azure and revealing hidden overproduction in the business.
Results
- Up to 90%[Result]Less execution time (from hours to minutes)
- 100%[Result]Azure migration completed
The problem
The materials explosion calculation process (MRP) was a strategic bottleneck blocking the Azure migration, forcing an on-premise server to be maintained. It took hours to execute, generated inaccurate results with high variation, and business data changes required re-executions that took days, causing undetected overproduction.
The solution
I applied exhaustive forensic analysis of SQL code (Performance Tuning) to identify bottlenecks, investigated hidden business processes causing data variations, and executed radical SQL process reengineering. Created a simple web interface to empower the end user, encapsulating technical complexity.
The challenge
Strategic and operational bottleneck
- Cloud migration blockage
- After migrating to Azure, this process (which took hours in the on-premise environment) became an obstacle, forcing a local server to be maintained for its execution, preventing cloud infrastructure consolidation and cost optimization.
- Critical business impact
- The process generated results with high variation and inaccuracies. Business data changes required a full re-execution that took days, affecting decision-making and leading to manual corrections months later, causing potential undetected overproduction.
The approach
The forensic diagnosis and architectural intervention
- Root cause investigation (SQL)
- I performed exhaustive analysis of the underlying SQL code (Performance Tuning) to identify bottlenecks that were consuming resources inefficiently.
- Business process mapping
- Beyond queries, I investigated hidden business processes influencing the data, discovering the variations causing calculation inaccuracy and consequent overproduction.
- Radical reengineering
- I optimized the SQL process, achieving up to a 90% time reduction (from hours to minutes). This eliminated the need to run the process on-premise and enabled its functional migration to cloud infrastructure.
The impact
The strategic impact and user empowerment
- Financial/strategic impact
- The forensic findings were presented to the business, revealing underlying overproduction and data variations. This enabled management to make informed decisions to correct processes and reduce inventory waste.
- Operational empowerment
- I created a simple web interface that encapsulated the SQL logic complexity and database connectivity. This allowed the process owner (without being a SQL or SAP expert) to execute the calculation multiple times daily for testing or immediate re-executions, ensuring real-time accurate data.
- Closing the cloud gap
- By optimizing the process, the on-premise server dependency was eliminated, fully consolidating the infrastructure in Azure and achieving the original migration objective.
