Data Quality Management
 Data quality management consists of the processes and practices of constantly
maintaining a high quality of information.
 Data quality management includes the process of identifying poor-quality
data, cleaning it, and making it usable with your business intelligence
platforms.
Why do you need data quality management?
 Data enters an organization in various ways, so not all the data is accurate and
perfect. It may be outdated, duplicated, or inconsistent.
If it is not accurate and consistent, you cannot use it to make important
decisions.
Making business decisions based on incorrect and unreliable data could cost
you a fortune.
 Data quality management helps you find the poor-quality
data and detect how it is coming into your database.
 Then you can clean that data and prevent more from entering
your database.
