| definition |
Reliability and application efficiency of data. Perception or assessment of a dataset's
fitness to serve its purpose in a given context. Aspects of data quality include:
Accuracy, Completeness, Update status, Relevance, Consistency across data sources,
Reliability, Appropriate presentation, Accessibility. Data quality is affected by
the way data are entered, stored and managed. Maintaining data quality requires going
through the data periodically and scrubbing it. Typically this involves updating,
standardising, and de-duplicating records to create a single view of the data, even
if it is stored in multiple disparate systems.
