This document outlines an agenda for a presentation on DB2 objects and SQL-PL. It discusses various DB2 concepts like data types, buffer pools, tablespaces, tables, stored procedures, functions, views, triggers, and the system catalog. It also describes several labs that will have attendees create and manage DB2 objects and write SQL-PL code. The goal is to provide fundamental knowledge on working with DB2 objects and the SQL procedural language.
