The 80% Warehouse (When Most of Your Data Just Sits There)

Your data warehouse has 847 tables. You're proud of it—years of work, terabytes of data, every system integrated. Then you check usage analytics: 680 tables haven't been queried in 90+ days. That's 80% of your warehouse sitting unused. Like a manufacturing plant with a giant warehouse where 80% of inventory just gathers dust—never moving to production, never creating value. Worse: you're paying to store it, maintain it, back it up, and document it. Every new table you add makes the problem worse. Users can't find what they need because they're drowning in unused tables. Your warehouse isn't an asset—it's a graveyard consuming resources.
