Data Engineering Case Study: 99% Accuracy & Faster Insights

Challenge & Solution

From Challenges to Measurable Gains

As Booking.com’s hotel partner ecosystem expanded globally, fragmented data formats, delayed activation, and inconsistent governance limited its ability to deliver timely insights, scalable personalization, and reliable reporting across teams.

The Challenges

Fragmented Partner Data

Hotel data arrived in inconsistent formats, limiting usability and trust.

Growing Compliance and Security Demands

Global scale required strict access governance and lineage visibility.

Delayed Data Activation

Business teams experienced long wait times to access clean, actionable data.

Low Confidence in Reporting

Conflicting reports and undefined standards eroded trust in insights.

Operational Bottlenecks

Engineering teams were overburdened by manual data support.

The Solutions

Unified Data Ingestion & Modeling

Built dedicated ingestion pipelines with standardized transformation and storage in Snowflake as a central source of truth.

Governance & Access Control Enablement

Implemented fine-grained access policies and full data lineage to support compliance and secure data consumption.

Transformation & Orchestration at Scale

Used PySpark, dbt, Airflow, and Kubernetes to automate ingestion, transformation, and scheduling across environments.

Standardization & Virtualized Consumption

Published transformed datasets as Snowflake views and integrated them into Salesforce Data Cloud for consistent activation.

Monitoring & Self-Service Enablement

Enabled Grafana dashboards and Slack alerts, reducing dependency on engineering and improving operational resilience.
