DATA QUALITY MEASUREMENT FOR ETL PROCESSES
First Claim
1. A computer-implemented method for maintaining data quality of transformed data generated using an Extract-Transform-Load (ETL) process and stored in at least one data warehouse, the method comprising:
- generating a quality metric for each of a plurality of units of the transformed data with reference to at least one data quality measurement rule, the quality metric for each unit of the transformed data representing a validity measure defined by the corresponding data quality measurement rule; and
generating a report organizing the quality metrics for selected units of the transformed data.
