Design Considerations

Front - End

  • Tableau
  • Dynamic Visuals
  • Interactive Dashboards

– Filters – Queries – Highlighters

  • Reporting Schemes
  • Security

Back - End

  • Database
  • Data Centralization
  • Data Automation

– SQL Server Stored Procedures – Windows Task Scheduler – Macro Implementation

Process Improvement

  • Battery data scattered across monthly, quarterly and annual reports
  • All reports stored in different locations
  • Lack of trending capabilities
  • Different template formats used over the years

Problem

  • Perform a one-time all inclusive data dump to SQL Server
  • Scheduled routine to import new battery reports
  • Use Tableau for data visualization
