Data Quality: Assess Data Integrity
Have a way to assess the data integrity so end users can trust the data and issues can be fixed quickly.
There are numerous ways to determine either directly or indirectly data quality. Can you provide more details on your needs?
Our customers have the same request. What comes to my mind is:
- interface Health Points (Device Status, Heartbeat, I/O Rate)
- AF analyses to check for staleness, out-of-range and/or Bad quality data
(see for example PI World Lab 2019: "Managing Time Series Data Quality for Business Data Owners and PI Administrators")
Is there anything else we could do to help customers identify issues with data quality?
