About Wonderful Copenhagen
Wonderful Copenhagen is the official tourism organization for the Capital Region of Denmark, promoting and developing both business and leisure tourism. The organization manages its business relations through Dynamics 365 — and, like many others, GDPR obliged it to rethink stronger data governance.
The challenge
The project was about more than GDPR compliance: Head of IT Michael Schuldt wanted to remove business-unit silos and give every team a unified view of the customer. Among the obstacles, data quality stood out — and duplicates were one of the greatest sinners. The team needed a tool to optimize data quality and clean up duplicates across all Dynamics 365 entities.
In their own words
Our team had tried various custom solutions to address our data challenges, but none proved to be effective in meeting our specific requirements. We needed a tool that could visually display data requirements for each entity, prevent users from saving or editing records before meeting business requirements, and efficiently scan and merge duplicated data.
Fortunately, we came across the Data Quality App and decided to give it a try. The results were outstanding! This app allowed us to define and execute our data quality rules and duplicate detection rules with ease and apply them to any Dynamics 365 entity. Additionally, the auto-merge feature saved us a significant amount of time that would have otherwise been spent on manual merging.
The best part about the app is that we now have complete control over our data, and can govern it effectively by preventing users and integrations from creating duplicate records. Overall, I highly recommend Techdio’s Data Quality App to anyone looking to optimize data quality, clean duplicate data elegantly, and maintain accurate data quality in Dynamics 365.
