Case Study: Tier-1 European Bank cuts test data prep time by 90% with DATAMIMIC

Tier-1 European Bank — Deterministic Test Data Across Oracle, MongoDB & Kafka

A Tier-1 European Bank's Analytics and API teams were stalled by a slow and fragile manual test data process. It took four weeks and multiple engineers to deliver masked data snapshots, which often broke JSON joins across their Oracle, MongoDB, and Kafka systems. This created significant delays for development and QA, prompting the bank to seek a solution from vendor DATAMIMIC.

DATAMIMIC implemented its ruleset-driven synthetic data solution to generate deterministic, compliant test data on-demand. This replaced the manual masking process and was integrated into the bank's Tosca DI and CI/CD pipelines. The results were transformative: test data preparation time was cut from up to 28 days down to 6-12 days, engineer hours were slashed, and parallel development increased from 0% to 90%. The solution also drastically reduced residual PII in pre-production environments, enhancing compliance.
