Looker: do the SQL once so others never have to
Set beside Mode, Looker looks like an investment in leverage. Instead of writing a fresh query for every request, analytics engineers encode joins and measures in LookML, and Looker generates the SQL whenever a business user picks fields in an Explore. The marketing lead filtering signups by channel and the CFO checking revenue by region both get queries written from the same definitions, without an analyst in the loop.
That leverage only arrives after the model exists. Building LookML that covers real business questions takes months, and every new metric or table becomes a model change that someone has to write and review. Looker is a poor fit for investigative work that will never be repeated, because modeling a question you will ask once is wasted effort.
