Data Quality as Measurable Data Characteristics
The properties of data naturally lead to the ability to measure them and identify data errors. These findings are pivotal in making data improvements through the uncovering and remediation of root-causes. Oftentimes, expectations of a dataset’s quality is more optimistic than true. Measuring data sets through activities like data profiling, a form of data analysis used to inspect data and its quality, can be used to determine its objective quality along structural, contentual, and relational dimensions.
Data Quality as Processes Controls
Data quality management applies quality management techniques to data. Data quality management is the planning, implementation, and control of activities to ensure that data is quality and that data is fit for use by downstream data consumers.
