Preface

Part 5: Advanced Programming Functions

In Part 5 we discuss the features of DB2 that support object-relational programming, such as user-defined functions, user -defined data types, and triggers. We also look at important aspects of application performance in terms of how to diagnose and tune problems. This includes looking at explain output and comparing it to available indexes and the SQL coding techniques.

Locking and concurrency is also a very important issue, because we have to be able to run several applications at the same time and to get the work through the system in an appropriate amount of time, while keeping the integrity of our data intact. In this section we look at all the options for locking and how to use them for best concurrency.

This book can be used as a self-study guide to help you prepare for the 514 DB2 Application Certification exam or simply as a guide to developing applications in a DB2 Universal Database V7.1 for OS/390 and z/OS environment. For information about the DB2 UDB family, refer to the other IBM certification books.
