What the best Framework/Package for data quality

[William_Scardua]

Hi everyone,

I’m currently looking for a data-quality solution for my environment. I don’t have DTL tables or a Unity Catalog in place.

In your opinion, what is the best framework or package to implement reliable data-quality checks under these conditions?

Thanks in advance!
