Titles of books in the library begin with DB2 Version 9.1 for z/OS. However,
references from one book in the library to another are shortened and do not
include the product name, version, and release. Instead, they point directly to the
section that holds the information.
If you are new to DB2 for z/OS, Introduction to DB2 for z/OS provides a
comprehensive introduction to DB2 Version 9.1 for z/OS. Topics included in this
book explain the basic concepts that are associated with relational database
management systems in general, and with DB2 for z/OS in particular.
The most rewarding task associated with a database management system is asking
questions of it and getting answers, the task called end use. Other tasks are also
necessary—defining the parameters of the system, putting the data in place, and so
on. The tasks that are associated with DB2 are grouped into the following major
categories.
Installation
If you are involved with DB2 only to install the system, DB2 Installation Guide
might be all you need.
If you will be using data sharing capabilities you also need DB2 Data Sharing:
Planning and Administration, which describes installation considerations for data
sharing.
End use
End users issue SQL statements to retrieve data. They can also insert, update, or
delete data, with SQL statements. They might need an introduction to SQL,
detailed instructions for using SPUFI, and an alphabetized reference to the types of
SQL statements. This information is found in DB2 Application Programming and SQL
Guide, and DB2 SQL Reference.
End users can also issue SQL statements through the DB2 Query Management
Facility (QMF) or some other program, and the library for that licensed program
might provide all the instruction or reference material they need. For a list of the
titles in the DB2 QMF library, see the bibliography at the end of this book.
Application programming
Some users access DB2 without knowing it, using programs that contain SQL
statements. DB2 application programmers write those programs. Because they
write SQL statements, they need the same resources that end users do.
Application programmers also need instructions for many other topics:
v How to transfer data between DB2 and a host program—written in Java, C, or
COBOL, for example
v How to prepare to compile a program that embeds SQL statements
v How to process data from two systems simultaneously, for example, DB2 and
IMS or DB2 and CICS
