             DB2 QUERY MANAGEMENT
                   FACILITY
                                            (Course No. 180.021)




The Query Management Facility (QMF) is a powerful tool for interactive ad hoc queries or report writing from
data stored in either DB2 or SQL/DS. Although the course focuses on the use of QMF with DB2, the content
applies equally to the use of QMF with SQL/DS.


QMF is interactive, and all of its functions can be used online, from creating and modifying a query to printing
a report. QMF commands are simple, and knowledge of just a few commands will enable you to be
productive. Hence QMF can benefit a variety of users, even if they know nothing about data processing
techniques.


QMF is widely used, with an ever increasing number of organizations recognising its benefits within the user
community. This course has already enabled numerous users, from every conceivable background, to
produce quality reports tailored to their specific requirements, without the need for complex programs or
lengthy delays and without having to rely on technical staff. QMF is so easy that it lets the user concentrate
on "what is to be done" rather than "how to do it".


The course also promotes a standard structure for end-user queries, which contributes to an orderly and
uniform reporting environment. These conventions rest on common sense. They permit the sharing of QMF
work and avoid duplication with its resulting loss of productivity.



OBJECTIVES
The QMF course will enable all participants to:
•       access data kept in DB2 or SQL/DS tables
•       perform calculations on that data
•       produce and print reports in many different formats
•       work interactively with QMF and other products.
