common_schema provides with server side scripting via QueryScript, analysis & informational views, and a function library, allowing for easier administration and diagnostics for MySQL. It introduces SQL based tools which simplify otherwise complex shell and client scripts, allowing the #DBA to be independent of operating system, installed packages and dependencies.
