Leverage your e-business
Use all your knowledge
resources
With its DB2 Extenders , DB2 Universal
Database can help you make use of all
types of data in your organization by
storing and managing multimedia
objects, such as text, images, video,
spatial and audio.
DB2 Extenders are a standard feature of
DB2 Universal Database. 2 Tightly
integrated into DB2, 3 the Extenders use
native DB2 services, improving multimedia
query performance.
DB2 supports multimedia objects on
Windows NT, OS/2, AS/400 and UNIX,
scaling all the way up to the largest
OS/390 parallel processing systems.
That’s important when you start storing
large objects in your database.
In addition, IBM partners offer a wide
variety of extenders—including spatial,
time series, currency, encryption and
optical. (For more information see
www.ibm.com/software/data/db2/
extenders.)
A new data type called DATALINK allows
you to protect the integrity of all your data
by referencing files that are stored outside
DB2, for example, in non-relational
databases. IBM DB2 Data Links Manager,
available on AIX, Windows NT and AS/400,
helps manage and control access to these
files through the DATALINK references.
Accommodate unique data types
If you need to support other types of
objects, DB2 allows you to create userdefined
types (UDTs), data types that
pertain to your particular application, and
user-defined functions (UDFs), which act
on these data types. You can store UDFs
on a central server for reuse in new
applications. In addition to saving
programming time, UDFs become a
business tool, ensuring consistent use of
data types and functions across applications
and enforcing business rules for
these data types across the enterprise.

DB2 Spatial Extender is an optional feature of DB2 DataJoiner.

Capitalize on DB2 for both
business intelligence and OLTP
Are you using one type of database for
transaction processing and another for
your decision support applications? If so,
you may be struggling with compatibility
and portability or investing heavily in
acquiring new database skills.
DB2 Universal Database gives you
parallel processing power to support a
variety of business intelligence applications
with complex queries or very large
databases. At the same time, it enables
you to safely support thousands of users
in a high-volume online transaction
processing (OLTP) environment, with a
cost-based optimizer that is second to
none. It even rewrites queries automatically
for better performance.
Parallel query
DB2 Universal Database boosts query
throughput by:
• Breaking a single user query into smaller
parts, which are executed simultaneously
across a parallel processing system
• Rewriting the query, if necessary, for
optimal performance
• Automatically creating access plans for
parallel execution, so that data scans, joins,
sorts, data loads, index creation, indexed
access, backup and restore are all
performed on all processors simultaneously.
When operating on an S/390 Parallel
Enterprise Server or Intel/RISC SMP
systems, DB2 Universal Database
distributes query processing across
multiple processors that share access to
all of the data. On other cluster platforms,
DB2 can distribute function and data
across multiple processors or groups of
multiple processors, which process the
data individually, combining the results for
the final output.
“The advanced data types and Extender
packages in DB2 have enabled us to create
search engines and advanced data mining
applications. … These applications have
empowered some of our clients to win
multimillion dollar contracts.”
—Marshall Freiman, Vice President of Product
Development, Web Emporium

Power your e-business
The industry applauds DB2
In March 1999, GartnerGroup’s Dataquest said
IBM regained its No.1 ranking in the worldwide
database market: “Strong performance from
the IBM S/390 and AS/400 systems along
with dramatic growth for DB2 on UNIX and
Windows NT allowed IBM to recapture the
market lead.”—Carolyn DiCenzo, Director and
Principal Analyst, DataQuest
“This database update issues a strong
challenge to rival Oracle with a bevy of
additions and enhancements.”
—Maggie Biggs, InfoWorld, May 24, 1999
“DB2 is shaping up as a top performer at a
bottom-dollar price. Its admin tools are where
they should be, and it offers great multimedia
data handling and programmability—the two
weaknesses of Microsoft SQL Server.”
—Timothy Dyck, PC Magazine, August 1999
“It’s all good for DB2: new markets, new
platforms, better and simpler pricing. DB2 is a
formidable offering.”—Mitch Kramer, Patricia
Seybold Group, in ComputerWorld, May 1999
“IBM solidifies a firm commitment to helping
businesses realize the full potential of
e-business and business intelligence. With
DB2 Satellite Edition and DB2 Everywhere,
combined with DB2 enterprise server and
connectivity technology, IBM offers … data
access and management solutions that
integrate the enterprise to a degree unsurpassed
in the industry.”—Carl Olofson, DBMS
Research Director, IDC, May 1999
Performance improvements
DB2 database software is designed to
perform optimally on each hardware
platform it supports. For example,
DB2 Universal Database for Windows NT
uses the Intel Virtual Interface Architecture
(VIA) to improve scalability on that
platform. As a result, you can run faster,
more complex queries on larger datasets,
maximizing your return on investment.
In addition, DB2 Universal Database
gives you added value with these
performance features:
• Support for summary tables to store
data summarized across tables (such
as averages), which optimizes
query processing
• Simultaneous backup and restore on
multiple tablespaces, which can exploit
the capacity of parallel systems
• Parallelism in utilities, such as parallel
index build during LOAD, to get data back
online sooner
• DRDA ® support for application programs
using three-part names for access,
for simplified coding and better
runtime performance
• Support for buffer pools of various sizes
assigned to specific tablespaces, which
allows you to optimize resource allocation.

Continuous availability
DB2 Universal Database makes it easy to
help keep your applications up and
running whenever your users are, by
offering the following features:
• Support for clustering in a variety of
operating environments, which allows you
to define a DB2 database that runs on
multiple servers
• Support for additional server nodes in
clusters to help maintain peak application
performance and throughput
• Support for high availability failover
mechanisms unique to each
operating system
• Faster restart and recovery to get your
users back to work sooner
• Online backup and REORG for continuous
availability or offline backup for
maximum efficiency
• Tablespace-level backup and recovery,
so you can recover only the table
spaces you need from the full database
backup image
• Point-in-time tablespace roll-forward,
which restores the database to a point
in time just before erroneous data
was introduced.
