platforms is about 90%
common, with 10% of the
code on each operating
system reserved for tight
integration into the
underlying OS.
 There are two other
members of the DB2 family
that are - DB2 for System i
and DB2 for System z with
95% portable SQL.
7
DB2 Everyplace is a small-footprint
(200-350 KB) relational
database and a high-performance
data
synchronization solution.
 It manages synchronization of
data from back-end data sources
such as DB2 9, Informix, Oracle,
Sybase, and MS SQL Server.
 It runs (with multithreaded
support) on a wide variety of
handheld devices, such as: Palm
OS, Microsoft Windows Mobile
Edition, Symbian, J2ME devices
like RIM's Blackberry pager

IBM DB2 9
Express Editions
DB2 Express Edition (or
DB2 Express) is an entry-level
8
data server that is
designed to be used on
microcomputers that have up
to two CPUs (a dual-core
processor is treated as a
single CPU), have up to 4 GB
of memory.
 DB2 Express Edition
Supports Linux, Solaris, or
Windows.
DB2 Express-C is a no-charge
entry-level data server
that is designed to be used on
microcomputers that have up

Warehousing tool, Administration Console, OLAP
Acceleration, Data Mining and Visualization Features
etc.
12

IBM DB2 9
DB2 Developer's Editions

applications (using JDBC, PHP, .Net, Python, ODBC, SQLJ and
Embedded SQL etc.) that interact with DB2 9 databases.DB2
provided with this edition cannot be used for production systems.
 DB2 Personal Developer’s Edition (PDE) contains DB2 Personal
Edition, DB2 Extenders, DB2 Connect Personal Edition, and a SDK
that can be used to develop applications.
 DB2 Universal Developer's Edition (UDE) is designed for any of
the DB2 client or server platforms available. Its Package contains
PDE + DB2 Everyplace, Express, Workgroup Server and Enterprise
Server Edition for each operating system supported.
 DB2 Enterprise Developer's Edition package contains UDE +
Informix Dynamic Server (IDS), Cloudscape, and DB2 Connect
Unlimited Edition for zSeries for each OS supported.
13

IBM DB2 9
DB2 for i5/OS is an
advanced, 64-bit relational
database management
system that leverages the On-
Demand capabilities of
System i, such as Dynamic
Logical Partitioning to
respond quickly to changing
workloads in order to ensure
business continuity in a
dynamic environment.
Unlike other DB2 editions,
DB2 for i5/OS is built directly
into the operating system.
14
DB2 for z/OS is a multi-user,
full-function database
management system that has
been designed specifically for
z/OS, IBM's flagship
mainframe operating system.
DB2 9 for z/OS is designed
to cut IT infrastructure costs
significantly, streamline efforts
to meet compliance
obligations, and simplify data
serving on the System z9
operating system.

IBM DB2 9
DB2 9 Clients
DB2 9 Runtime Client
DB2 9 Client
Includes all the functions found
in the DB2 Runtime Client plus
functions for client-server
This 2 MB fully redistributable
client provides JDBC and
SQLJ applications access to
DB2 data servers without
installing and maintaining DB2
client code.
New in DB2 9, this client
performs similar functions to
the JCC client, but instead of
supporting configuration, Java-database
based access
to a DB2 data server it's used
for CLI/ODBC applications.
Java Common Client (JCC)
DB2 9 Client Lite
15
The best option if your only
requirements are to enable
applications to access DB2 9
data servers. They provide the
APIs necessary to perform this
task, but this client comes with
administration, and application
development through a set of
no management tools.
rich graphical tools.

IBM DB2 9

16

IBM DB2 9
DB2 9 Connect
DB2 Connect provides a robust, highly scalable
communications infrastructure for connecting Linux,
UNIX, Windows, and mobile applications to data
stored in z/OS (mainframe) and i5/OS (minicomputer)
databases.
DB2 Connect is an add-on product that must be
purchased separately unless DB2 Enterprise Server
Edition, which provides a limited-use version, is
installed.
17

IBM DB2 9
Versions of DB2 Connect
DB2 Connect Personal Edition: Intended to be used by a
single user on a single workstation who needs connection to
any number of mainframe and/or minicomputer DB servers.
DB2 Connect Enterprise Edition: Intended to be used by
multiple users on multiple workstations who need connection to
any number of mainframe and/or minicomputer database
servers. User based licensing.
DB2 Connect Application Server Edition: same as
Enterprise Edition, however, license based on the number of
processors being used by Web or application servers
DB2 Connect Unlimited Edition: same as Enterprise Edition,
however, license charges are based on Millions of Service
Units (MSUs) per hour.
18

IBM DB2 9
DB2 9 Extenders
Extenders extend the basic functionality and
capabilities of a DB2 database by providing a rich set
of built-in data types, along with a set of functions that
are designed to work with each data type provided.
They are:
- Audio, Video, and Image (AVI) Extender
- Text Extender
- Net Search Extender
- XML Extender
- Spatial Extender
- Geodetic Extender
19

IBM DB2 9
AVI Extender - contains a set of user-defined data
types and functions that allow a DB2 database to store
and manipulate nontraditional data such as audio
clips, movies, and pictures.
Text Extender – Its powerful linguistic search and
text-mining capability allows users to construct queries
that will search through any kind of text document (in
DB or File system)
Net Search Extender - well suited for high-end e-business
20
applications where search performance on
large indexes can be critical and the ability to scale
the processing of concurrent queries is needed.

IBM DB2 9
XML Extender - contains a set of user-defined data types
and functions that can be used to store XML documents in
a database (as character data or in external files) and to
manipulate them, regardless of where they are stored.
Spatial Extender - With its capability, you can generate,
analyze, and exploit spatial information about geographic
features, such as the locations of office buildings or the
size of a flood zone, and present it in a 3D format.
Geodetic Extender - It treats the Earth like a globe rather
than a flat map thus making it easier to develop
applications for business intelligence and e-government
that require geographical location analysis, uses a
latitude/longitude coordinate system.

Data Warehousing
 Systems that contain operational data -- the data that runs the
daily transactions of a business -- contain information that
business analysts can use to better understand how the
business is operating.
 In data warehousing, you create stores of informational data
-- data that is extracted from operational data and then
transformed and cleansed for end-user decision making.
 End users can query the separate database (the warehouse)
without affecting the operational databases.
 DB2 is built for business intelligence. Not only is DB2 the
world's most scalable database, but it also has a robust set of
business intelligence functions.

IBM DB2 9
On-Line Analytical Processing (OLAP)
"What is my profitability for the third quarter across
the southeast region of India for my focus products?”
The above question requires multiple
perspectives on data, such as time,
regions, Countries and products.
These perspectives are called dimensions.
OLAP server processes multidimensional
requests that calculate, consolidate, and
retrieve information from a multidimensional
database, a relational database, or both.
46
Q

IBM DB2 9
DB2 as an OLAP Server
There are two common categories of OLAP:
- Multidimensional OLAP (MOLAP)
- Relational OLAP (ROLAP).
DB2 can work with both. MOLAP is handled by
the DB2 OLAP Server product and ROLAP by
the native data stores in DB2.
