Implementing Practical DB2 Applications
provides a concise source of information for the development and implication of applications using IBM's DB2 relational database package in the MVS environment. The book describes the flagship DB2 version, namely that implemented for the MVS operating system environment where DB2 operates with the MVS transaction processing subsystems: CICS, IMS and TSO.
The book is intended for both beginners and experts. It describes how the various components of SQL are used to provide practical applications.
Containing tips and notes that were discovered the hard way - through hands on experience - this book will be welcomed by all those looking to implement applications in DB2.
