Handle pureXML data in Java applications with pureQuery
pureQuery and DB2 pureXML are revolutionary database technologies in
their fields. pureQuery is a high-performance Java data access platform
focused on simplifying the tasks of developing and managing applications that
access data from a database. pureXML is the native XML data management
technology introduced in DB2 9. It consists of a hierarchical storage
technology, XML querying languages (XQuery and SQL/XML), XML indexing
technology and other XML-related features. This article brings them together
by showing how you can develop pureQuery applications that handle pureXML data
so you can get the best performance and manageability from your DB2
application.

Expanding clustered topologies for WebSphere Process Server and WebSphere Enterprise
Service Bus
Learn how and when to grow clustered topologies that use IBM WebSphere Process
Server and WebSphere Enterprise Service Bus. When new BPM and ESB applications are
deployed, you may need to expand the initial topology to take advantage of increased IT
resources (such as memory) or to isolate applications. This article describes a standard
"golden topology" widely used in production deployments, and then examines how to grow
the topology from within the cluster, and by adding new clusters. It describes good and
bad design patterns, what to consider, and the costs and limitations of each approach.
The article also describes how to plan for Service Integration Bus connectivity and desired
messaging engine behavior.

Thinking XML: Analyze financial reporting using XBRL
Thanks to recent events, the world turns its eyes to Wall Street. One of the hot topics is how to increase the transparency of descriptions of business activity and financial results. The financial sector and the SEC have long approached this problem with XBRL, an XML language for business reports. XBRL uses a variety of XML technologies, including XLink to provide rich detail for financial information. Learn to interpret and analyze financial report information in XBRL, using an actual U.S. Securities and Exchange Commission report as an example.

Software as a service: Build a Web-delivered SaaS framework for forms and
workflow-driven applications
Software as a service (SaaS), largely enabled by the Internet and
corporate intranets, has become an innovative way for enterprises to do
business. In the past, software had to be installed in an infrastructure close
to end users. The current industrywide trend is for Internet-based services.
Deployment of software as a service, accessible on the Internet and supported
by multitenant architecture, makes new applications (or tenants) available
with significantly lower costs. In this article, learn how a team built a
Web-delivered SaaS framework to host applications, from different business
domains, that were driven by forms and workflow.

Solve the Chinese geography translation problem in Google Maps
programming
Google Maps is a free service that provides browser-based directions as well as maps of particular locations through the Internet. You can zoom in on the interactive maps to show detailed information, providing great user interactivity with the Web site. The maps provided by Google can be used not only directly by customers, but also to develop customized map services and products with the Google Maps API. The latest Google Maps API version, however, is not good at parsing Chinese geography, which makes it difficult to use in applications for a Chinese audience. In this article, we describe a feasible solution, combining other Web services, to parse Chinese geography with the current Google Maps API for a Chinese mapping solution. We'll use the example of the sites for the Beijing 2008 Olympic Games to demonstrate our solution.

Comparing XML database approaches
The increasing use of XML asks for systems that store semi-structured data
without forcing it into inadequate data structures. These requirements are met by both
native XML databases and relational databases with integrated XML support. The
question is: Why should you prefer a native XML database over an XML-aware classic database or the other way around? This article compares the approaches for a number of varying solutions, including eXist, Mark Logic, and IBM DB2 Express-C. The differences are translated into practical advantages and disadvantages.

Infrastructure architecture essentials, Part 3: System design methods for scaling
In an ideal world, all systems would have linear scaling of all
resources with linear cost, but this is rarely the case. Cost may include not
only capital expenditures but operational costs for increased cooling, power,
rack space, and management requirements. System designers and solution
architects who plan ahead for scaling can at least control cost, make initial
trade-offs for the long term, and provide mostly linear scaling with similar
increases in capital and operating costs. Choosing the right scaling
strategy--ranging from simple server-client to clusters to grid, cloud, or
general Internet services--up front is critical. This article arms systems
designers and solution architects with methods for success.

Systems will always have resource limits that define performance bounds. The term

stage in processing that leaves costly resources underutilized. In theory, a perfectly
resource-balanced, infinitely scalable system should never have a bottleneck or
wasted resources. Discover methods and tools for finding, eliminating, and avoiding system
bottlenecks so that you can provide the highest performance at the lowest cost for

The business analyst in model-driven architecture
From a software development viewpoint, model-driven architecture (MDA) encourages
efficient use of system models. It also encourages reusing best practices as families of
systems are produced. One of the main aims of MDA is to separate design from architecture,
which places the business analyst in a unique and potentially powerful position within the
organization. Learn how you as a business analyst can take an active role in this type of
architecture.

Best practices for SOA nonfunctional testing
In the course of developing a Service-Oriented Architecture (SOA)
application, your organization will most likely have nonfunctional
requirements (NFRs) that need significant implementation and testing. Shiv
Asthana describes the best practices you should adhere to when testing
nonfunctional requirements for applications built as part of an SOA
environment.

Needs-based versus features-based SOA: Get the right focus for your SOA
initiative
One misconception about Service-Oriented Architecture (SOA) is that the
service part means Web services. In a real-life scenario, this can lead to
building a bunch of services (ABOS) rather than developing a true SOA. This
article explains what constitutes a service, and describes the various needs
of an SOA solution and how to identify those needs for your SOA scenario. This
approach puts the focus of the SOA initiative on the benefits and on the
phases of the SOA solution.

Architectural manifesto: Adopting agile development, Part 6
In Part 6 of this series,
learn about buying software development services from the customer's point of
view. While there's a lot of information for development teams about using
agile methodologies, there isn't much material about the customer's viewpoint
when buying software development services. Learn how customer incentives,
behavior, and the pricing models of a project have a huge effect on the
current and future success of a development project.

SCA asynchronous invocation patterns in depth
Service Component Architecture (SCA), a next-generation programming
model, provides three kinds of asynchronous invocation patterns. You
can use those patterns to asynchronously invoke target SCA services without
knowing how the request and response messages are "magically" processed. This
article explains what happens when you issue an asynchronous
request and how the SCA run time handles the asynchronous messages in the
messaging systems. Learn how to develop a
mediation handler to monitor the SCA asynchronous messages and how to use the mediation handler to analyze asynchronous
invocations.

Architecting intrusion-detection solutions
Intrusion-detection systems (IDSs) have become an increasingly important part of the
security strategy of many organizations. An IDS plays a key role in the concept of
defense-in-depth, being only one of several deployed countermeasures designed to deter,
slow down, and detect an attack before it occurs or before more serious actions occur.
Discover the different types of IDSs and what types of attacks each can detect (or not
detect), and see issues to consider when planning an IDS deployment.
