Chapter 4. Deploying applications with

DB2

In this chapter, we discuss deploying various applications with DB2 drivers. We

introduce deployment on Java, C/C++, PHP, Ruby, Python, Perl, and .NET.

We focus on how to access a DB2 database from various applications without

installing a full DB2 Client. We introduce DB2 products that facilitate this

functionality and ways to deploy them with your application.
