Data Quality Assurance

A Multi-Layered Approach At EODHD, we understand that the accuracy and reliability of our data are paramount. To ensure the highest levels of data quality, we have implemented a multi-layered approach to data validation and error correction. Once the data has been collected and processed through algorithms, our proprietary data quality assurance system takes over.

This system consists of a series of checks, designed to identify and rectify any potential issues in the data. Our algorithms compare the extracted information against historical data, industry benchmarks, and other relevant sources to detect any anomalies or outliers. The system automatically triggers a series of corrective measures when it identifies discrepancies, ensuring that it cleans the data.

By automating the data quality assurance process, we can maintain the integrity of our financial data on a scale that would be impossible to achieve through manual checks alone. This multi-layered approach to data validation, combined with advanced data processing techniques, ensures our commitment to delivering reliable financial information.
