Section -1) Planning
Main Point: IBM is continuing to evolve and enhance the value that we bring to companies by building on the SOA announcements we made last fall…today we are going to talk to you about how a Business Centric Perspective to SOA is necessary to drive innovation that matters*
As you know, SOA is one of IBM’s long term strategies to enable innovation that matters. IBM will continue to deliver SOA centric offerings. But we also want you to know that IBM’s view of SOA is business centric. and we’ll talk about this important concept. Further, we’ll discuss ways to get started through existing parts of your business (people process, information). Additionally, we’ll show how reuse and connectivity is critical to support the business centric approach. We’ll then give you detail on how the specific entry points are accelerated by SOA Foundation products and the business insight these products provide.
Lastly, we’ll discuss an important part of the story called SOA Governance to ensure we’re aligning the business with IT.

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
IBM DB2 9
Express Editions
DB2 Express Edition (or DB2 Express) is an entry-level 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 to two CPUs, have up to 4 GB of memory, and are running a supported version of Linux or Windows.
Where pureXML is available as an add-on feature for DB2 Express, it is included with DB2 Express-C but missed many other features of Express Edition.

Scalable on Demand:
no application or database changes required for other DB2 Editions
Application Development Flexibility
Innovative Technology
Viper--Industry first relational and XML data server
1. As with DB2 Express Edition, DB2 Express-C may be deployed on all systems with up to 2 processor cores, and on AMD or Intel x86 systems with up to 2 dual-core chips. 4 GB of memory is the maximum supported. There is no limit to database size however. Other editions of DB2 exist to support larger servers or clusters of servers with a seamless upgrade from DB2 Express-C.
2. Innovative technology -- DB2 Express-C will be refreshed with the forthcoming "Viper" release of DB2 currently in beta test. DB2 "Viper" is the industry’s first hybrid data server -– delivering superior performance managing both XML and relational data structures. Early adopters have cited cost savings achieved through reduced development time and improved performance of applications using XML and relational data. These values provide critical advantages for the growing number of solutions implementing a service oriented architecture (SOA) and working with XML-based vertical industry standards.
3. Software development communities, environments and languages supported include PHP, Python, Perl, Rational Web Developer, .NET with Microsoft Visual Studio, Java with Eclipse, Quest Toad for DB2, Zend Studio and Zend Core for IBM. DB2 Express-C offers broad development environment flexibility

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:
Text Extender
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 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.

SQL Assistance
It’s a graphical tool you can use to build SELECT, INSERT, UPDATE, and
DELETE statements.
Notes:
DB2 9 has an integrated development environment (IDE) called the DB2 Developer Workbench (DB2 DWB), specifically designed for power DBAs and developers who are required to build business logic for their databases. The DB2 9 DWB replaces the DB2 8 Development Center (DB2 DC), which was a successor to the DB2 7 Stored Procedure Builder (DB2 SPB). The DB2 DWB is a completely different tool that's built on the Eclipse foundation, so the interface is identical to other DB2 products that use this architecture, such as DB2 SQL Warehousing Tool, Rational Application Developer, Rational Data Architect, and more.
The DB2 DWB is a rapid iterative development environment that can be used for building stored procedures (SPs), user-defined functions (UDFs), and structured data types. It is also useful for creating XQuery statements, registering XML schemas, annotating XML Schema documents for shredding, SQLJ development, and much more.
In DB2 9.5, the DB2 Developer Workbench has been replaced with the IBM Data Studio, which is also Eclipse-based.

Notes:
The Memory Visualizer helps DBAs understand their systems' memory allocations on a per-instance basis. You can start this tool by right-clicking the instance you want to work with in the Control Center and selecting View Memory Usage. You can also select the tool directly from the Start menu in a Windows environment. The figure shows the Memory Visualizer monitoring an instance called DB2.
IBM DB2 9
Notes:
DB2 has a Storage Management tool that helps DBAs understand their storage requirements and potential considerations. DB2 9 includes automated storage management where DB2 can automatically grow containers that require more space, and even manage the table spaces (this feature is available with DMS FILE-based table spaces only). If you're using the automated storage management capabilities in DB2 9, the Storage Management tool may not be as useful if you choose a manual-based storage mechanism for your data server.
You can use the Storage Management tool to schedule or immediately capture a snapshot of currently allocated storage resources. Start the Storage Management tool by selecting a database in the Control Center, right-clicking, and selecting View Storage.
IBM DB2 9
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
"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.
165.unknown
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.
IBM DB2 9
An integrated data warehouse for greater business insight
Identify opportunities to pursue - before the competition does
Identify risks to be minimized or eliminated - before they become public
Notes:
OLTP (On-Line Transaction Processing)
An OLTP system is typical of a Web ordering system, where you perform transactions over the Web (such as ordering a product). These applications are characterized by granular single-row look-ups with logic that likely updates a small number of records.
Systems that contain operational data -- the data that runs the daily transactions of a business -- are OLTP systems.
BI (Business Intelligence)
DB2 is built for business intelligence. Not only is DB2 the world's most scalable database, it also has a robust set of business intelligence functions. DB2 has two Data Warehouse Editions (DB2 DWE) that provide steep discounts on a complete set of data warehousing tools. Some of these tools are available for purchase outside of the DB2 DWE packages, and some are not. DB2 DWE comes in the Base and Enterprise Editions.
The DB2 DWE builds on and extends the powerful DB2 Enterprise 9 product to provide improved performance and usability of data warehousing, and analytics features, for real-time insight and decision making to achieve information on demand. DB2 DWE features include tools for warehouse management, analytic application development, OLAP, data mining, and very large database (VLDB) query and resource management.
This has been renamed to DB2 Warehouse for DB2 9.5 in the 9.5 version of the product.
