By Pete Stiglich<\/em><\/p>\n\n\n\n

Explains a practical dimensional-modeling pattern for handling imperfect source data without destroying analytical trust. Instead of rejecting records with invalid dates or other validity issues, the approach creates a \u2018Data Validity\u2019 dimension with a surrogate key and multiple Y\/N flags describing different validity exceptions. Facts reference this dimension so analysts can filter invalid cases, compare results with\/without errors, and quantify issues for upstream correction. The article also shows how to populate the dimension via a controlled Cartesian-product technique and how the pattern can reduce skew and improve confidence.<\/p>\n\n\n\n
