About Family
The code on the Linux, UNIX, and Windows (luw) 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.
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

DB2 9 Clients
DB2 9 Runtime Client
DB2 9 Client
Java Common Client (JCC)
DB2 9 Client Lite
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
no management tools.
Includes all the functions found in the DB2 Runtime Client plus
functions for client-server configuration, database
administration, and application development through a set of
rich graphical tools.
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 Java-based access to a DB2 data server it's used for CLI/ODBC applications.

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 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
21
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.

Q
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.
IBM DB2 9
47
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.
