Target Audience

This course provides the applications programmer with an in-depth knowledge of the DB2 development process. It is aimed at programmers who need to code or support DB2 application programs written in C or Java.

Pre-requisites

The delegate should be familiar with the host environment, together with a working knowledge program development using either C or Java.

Course Objectives

The aim of this course is to provide the programmer, unfamiliar with DB2, with the necessary skills required to define, access and manipulate DB2 data, either via an application program or using the Command and Control Centres. On completion of this course the student will be able to:

set up a DB2 test environment, using correctly defined tables, views, indexes, synonyms and aliases
code SQL statements to read and manipulate DB2 data
develop, prepare and execute DB2 programs
bind packages
use non-scrollable and scrollable cursors
describe the locking process used by DB2
use the DB2 for Windows GUI Toolset
use the Command Line Processor
populate tables using DB2 Utilities
monitor application performance

Course Environment

The lectures apply to DB2 UDB running in a Linux, Unix or Windows environment.

Course Format

The course contains many practical exercises to ensure familiarity with the product. Initially students create Tables and Indexes, and then proceed to develop Java or C programs accessing the data held on the DB2 Tables. On completion of this course students will be ready to start the development of application programs accessing DB2 data. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
