The challenge
Manual efforts and evolving schema with outpaced legacy systems
Legacy data systems struggled to handle growing data volumes, evolving schemas, frequent updates, and complex access requirements. Their limited scalability and unreliable refresh capabilities led to stale, inconsistent data. As a result, many businesses resorted to manual processing, causing delays and fragmented insights, ultimately hindering timely decision-making, secure collaboration, and agility across the product lifecycle.
Key challenges
Delayed insights from non-scalable data architecture
High manual overhead in transformation processes
Limited secure access for diverse business units
No clear lineage or governance across data layers
Schema evolution in critical datasets
The solution
Medallion architecture for evolving schema and RLS to govern at scale
Dynamic data modeling
Metadata-driven schema generation
4-hour schema refreshes
Parallel refresh pipelines
Safe transformation
Access and governance
Maintaining mappings for various business and AAD groups for RLS
Audit-ready admin/user group separation
Role-based access and filtering
Implementation approach
1
Robust data architecture for scalable, secure analytic
4-hour refresh
Validated tables
Schema handled
2
Validation process
Pre-check schema changes, datatype changes
1-hour gap with respect to 4-hour refresh
Secure access
3
Security model
AAD mapping
Role filters
Admin/user split
The impact
Automating complexity, streamlining data migration, and accelerating outcomes
Operational agility
Timely insights replace lagging reports
Fast iteration on product decisions
Better coordination across production teams
Defined development lifecycle through metadata driven datasets
Data governance
Secure, role-specific access at scale
No manual filtering, system enforced
Auditable mapping via AAD and context keys
System performance
Minimized manual errors and rework
High-volume parallel pipeline execution
Better modelled data to create a presentation layer
Looking ahead
