Data Quality Solution
Outline of the Challenge:
A public sector company faced significant challenges with data quality across its diverse and complex data sources. Inconsistent data quality led to inaccuracies in reporting, compliance issues, and inefficiencies in decision-making processes.
The company required a robust solution that could unify business and technical stakeholders to define data quality (DQ) rules and execute these rules seamlessly across various platforms. The solution needed to provide detailed data quality reports and dashboards, highlighting erroneous records for further inspection.
Proposed Solution
Data Hiro proposed a custom-made data quality solution based on an enterprise data model, developed using Python. This solution enabled collaboration between business and technical teams to define model-driven DQ rules. The solution was designed to execute DQ rules on any platform and present the results in a reporting platform with comprehensive dashboards and detailed data quality reports.
