The "long story" sometimes ends badly. If a developer leaves a localhost.sql file in a public web directory, anyone can download it to see the entire database structure and, in some cases, sensitive user data or administrative credentials that were used during testing.
include their local database backups in their code uploads so others can replicate their environment. localhost.sql

Since the local server is almost always named "localhost," the resulting file becomes localhost.sql . 2. The Bridge to Production The "long story" sometimes ends badly
