About the Course

This course is designed to enable users to evaluate the quality of data in the information system according to a set of metrics and thresholds based on a series of indicators, models and rules for each data item to be analysed or monitored. And also to use tools to isolate, correct and monitor non-compliant values in a dataset. It combines the Talend Data Quality Basics training contents with other contents covering the collaborative work and the correction of data issues.
