What tools are available for data quality measurement in a Nova database?
Given the data-driven nature of Nova, what tools are available to monitor data quality in a Production environment?
By data quality, I mean a measure of these kind of phenomena: 1. Data being inconsistent (not following business rules) eg: instance "vm_mode" is "deleted" but the "deleted" flag is "False"; 2. Data being invalid. Perhaps due to an upgrade, some previously acceptable value now causes some error.
