IBM licensed programs: Database accessories 617
Draft Document for Review October 18, 2004 5486LPDb.fm
Solutions and benefits
The DB2 Query Manager and SQL Development Kit for iSeries provides
precompilers and tools to assist in developing SQL applications and queries.
Once created, the applications and queries can be restored and run on other
systems that do not have this product installed.
A significant advantage of the DB2 UDB for iSeries database manager, along
with Query Manager and SQL Development Kit, is that DB2 UDB for iSeries SQL
objects are compatible with OS/400 objects.
Features
Most SQL functions may be performed either interactively or in application
programs written in one of the following high-level programming languages:
RPG, COBOL, C, PL/I, and REXX. Other features include:
SQL may be used to define tables (physical files) and views (logical files).
This is similar to a DDS definition of a file. For example, you can create tables
and views that include column/field definitions, such as the name and data
attributes. A user may also maintain the tables/files and views.
SQL statements may be used to perform a query on a table or view. The
system responds with the records that meet the criteria for the columns/fields
requested.
SQL statements may be used to perform maintenance of table/file data by
specifying selection criteria and new values.
The support of SQL allows program developers to write applications that can
be transported easily to different IBM system architectures that support SQL.
An SQL Assist function in iSeries Navigator helps to create SQL statements
that can be used to create and run queries and reports.
A Predictive Query Governor can control long running queries.
Non-programmer functions
Query Manager furnishes a report customizing interface. This interface enables
non-programmers to tailor reports separately from the method of extracting the
data. This improves productivity by permitting the users to change report design
without re-accessing the original database. The resulting report objects are
compliant with the OS/400 Query Management CPI and, therefore, are portable
to other SAA environments.
