I ran into this problem when an e-commerce client asked why their best customers kept disappearing after month two. The obvious metrics told us nothing. What we needed was a way to watch user behavior unfold over time, which is…
I ran into this problem during a data migration when a colleague handed me a CSV full of product codes like “SKU-4829-A” and “ORD-1034-B” — and I needed to pull out just the numbers for validation. Manual extraction was not…
