About Family

The code on the Linux,

UNIX, and Windows (luw)

platforms is about 90%

common, with 10% of thecode on each operating

system reserved for tight

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

underlying OS.

There are two other

members of the DB2 family

that are - DB2 for System iand DB2 for System z with

95% portable SQL.

, , ,

Sybase, and MS SQL Server.

It runs (with multithreaded

support) on a wide variety of

handheld devices, such as: PalmOS, Microsoft Windows Mobile

Edition, Symbian, J2ME devices

like RIM's Blackberry pager

IBM DB2 9

DB2 Enterprise Server EditionDB2 Enterprise Server Edition is the ideal foundation for

building multi-terabyte data warehouses, high-availability, high-

volume OLTP systems, or Web-based Business Intelligence

(BI) solutions and mission-critical applications on SAP.

It is designed to be used on any size of server (from one to

hundreds of CPUs) that is running Enterprise Linux & Windows,

10

AIX, HP-UX, Solaris or Novell operating systems.This edition includes all of the functionality found in DB2

Workgroup Edition, plus features that are needed to handle

high user loads and provide 24x7x365 availability.

It comes packaged with DB2 Connect that allows it to

participate in heterogeneous networks using the Distributed

Relational Database Architecture (DRDA) protocol.



IBM DB2 9

DB2 Data Warehouse EditionIt is designed for today's data center environments,

where OLTP and decision support are merged into

integrated information management systems.

The core engine for DB2 Data Warehouse Edition is

11

Partitioning Feature.

In addition, it also comprised of Design Studio, SQL

Warehousing tool, Administration Console, OLAPAcceleration, Data Mining and Visualization Features

etc.

DB2 9 ExtendersExtenders 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 thatare designed to work with each data type provided.

They are:

15

Audio, Video, and Image (AVI) Extender Text Extender

Net Search Extender

XML Extender

Spatial Extender

Geodetic Extender



IBM DB2 9

AVI Extender - contains a set of user-defined datatypes 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

16

a w searc roug any n o ex ocumen nDB or File system)

Net Search Extender - well suited for high-end e-

business applications where search performance onlarge 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 buildin s or the

17

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-governmentthat require geographical location analysis, uses a

latitude/longitude coordinate system.
