Explanation

DB2's Command Editor provides the capability to execute SQL statements and view graphical representations of access plans (also called explain plans or visual explain). This feature helps developers and DBAs understand how DB2 will execute their queries, including index usage and join methods. Task Center is for scheduling tasks, Design Advisor suggests optimizations, and CLP is command-line only.
