The idea

A source of truth designed for reporting, analytics and AI.

GAT System builds data warehouses that convert operational records into consistent analytical information. A well-designed warehouse organizes history, business dimensions and measures so dashboards and reports use trusted, reusable data.

Solutions are designed to work with the organization’s existing data landscape, Microsoft technology strategy, security requirements and operating processes.

Best fit

For teams ready to turn a clear need into a useful capability.

  • Finance, retail, supply chain and commercial reporting teams
  • Organizations needing reliable history across several operational systems
  • Teams planning dimensional models for BI and enterprise reporting
Where it helps

Best for slow, fragmented orhard-to-scale data processes.

  • Operational systems are difficult to query consistently
  • History, master data and business rules vary between reports
  • Reporting workloads affect production systems or take too long
What we build

End-to-end service scope
