Case Study: a leading airport and travel retail operator achieves seamless data governance and zero-disruption analytics with Nagarro and Databricks Unity Catalog

World’s Leading Airport and Travel Retail Operators cuts migration time by 60% with Nagarro

A world-leading airport and travel retail operator faced challenges with a fragmented data landscape, as its various business units operated with inconsistent governance and access controls. This created operational inefficiencies and security concerns. To address this, Nagarro was brought in to leverage Databrick's Unity Catalog, aiming to unify the platform without causing business disruption.

Nagarro implemented a solution using Unity Catalog to centralize governance, employing business-aligned catalogs and a dual metastore sync for real-time data mirroring. This ensured zero disruption to analytics and reports during the migration. The results were significant, with a 60% reduction in migration time and the successful refactoring of over 1,500 notebooks. All teams now operate on a single, governed platform with full security compliance and uninterrupted access.
