Answer Posted / ashish kumar

A DB2 bind is a process that builds an access path to DB2
tables.

A BIND process establishes a relationship between an APPLICATION
PROGRAM and its RELATIONAL DATA.
A plan is an executable module containing the access path logic
produced by the Db2 optimizer. It can be composed of one or
more DBRMs and packages.
The plans are available in the Catalog table SYSIBM.SYSPLAN

DB2 Bind compiles all your sql statements(dbrm) into an
executable format.
It uses DB2 Optimizer to create the better access path.
Package is the executable access path code for the sql
statements in the DBRM

Plan contains package list which is nothing but pointers to
packages.
