DB2 Concepts & Facilities Training

Course#: WA1889

First, the concepts of DB2 are presented and discussed. The major features of the Structured Query Language (SQL) are presented as the means to access DB2 data (and to create and secure DB2 components).  Several of the “special features” of SQL are presented. Optionally, guided, hands-on, practice sessions give each attendee an opportunity to use SQL to access data.  QMF and/or SPUFI are used to execute SQL statements. DB2 database design and Referential Integrity (RI) are discussed.

An overview of DB2 (SQL) programming concepts are presented and discussed. DB2 performance guidelines are discussed.  Optionally, the use of the SQL statement EXPLAIN PLAN is used to help to evaluate the efficiency of SQL statements.

The following “Release Dependent” features are also covered –

  • Version 8 – Additional SQL features
  • Version 9 – Additional SQL features, including pureXML
  • Version 10 – Preview

Optionally, a demonstration is provided of DB2 for WINDOWs to show "future" features for DB2 for OS/390.  These features include Recursive SQL, the WITH SQL feature, GROUPING SETS, ROLLUP and Visual Explain.
