@nizzyabi They are now AI boot camps led by those with a sliver more experience than their target audience.

An AI strategy is only as strong as the foundation beneath it. Shiny tools won’t fix vague goals, siloed teams, weak governance, or poor measurement. Build the foundation first. Then scale.

Location queries can get expensive fast. A geospatial index helps by narrowing the search space before the database performs the precise spatial calculation. Instead of checking every point, it asks: Which regions could contain a match? Then the database applies the exact geometry check to that much smaller candidate set. That is what makes queries like nearest neighbor, radius searches, point in polygon, geofencing, and map filtering scale much better. Same data. Fewer points to check. 📍 #sql #databases #dataengineering
