Parallel processing of unstructured data, Part 1: With DB2 LUW and GPFS SNC
Learn how unstructured data can be processed in parallel fashion -- within a machine and across a series of machines -- by leveraging DB2 Linux, UNIX, and Windows and GPFS SNC to provide efficient highly scalable access to unstructured data, all through a standard SQL interface. Realize this capability with clusters of commodity hardware, suitable for provisioning in the cloud or directly on bare metal clusters of commodity hardware. Scalability is achieved within the framework via the principle of computation locality. Computation is performed local to the host which has direct data access, thus minimizing or eliminating network bandwidth requirements and eliminating the need for any shared compute resource.

Enhance IBM Intelligent Operations Center-based applications
The IBM Intelligent Operations Center supports standard operating procedures. When an incident occurs an activity is created for each step defined in a procedure. This article describes how architects and developers can modify existing artifacts, and develop new ones, to present data to and collect data from a user as a part of an activity, then record both presented data and collected data, and propagate it to a later activity as part of the same incident.

Boost IBM InfoSphere Streams performance with Linux channel bonding
Have you ever wondered if Linux channel bonding would allow you to get faster throughput using IBM InfoSphere Streams? We have answered that question when running InfoSphere Streams release 2.0.0.2 on Red Hat Enterprise Linux release 5.5. In this article, we describe what channel bonding is at a high level, how we set up our test environment, and the results we observed. In our experiments, channel bonding increased bandwidth by as much as 68 percent.

Design a message and service definition integration strategy based on Common Information Model standards
Users of IBM Rational Software Architect are familiar with its UML modeling capabilities, as well as its ability to transform a model into other domains, including Java, XSD, and WSDL. However, when it comes to using an energy industry information model and evolving the model into definitive message and service definitions that can be used directly in an SOA messaging infrastructure, there is very little guidance. This article describes a process and the use of Rational Software Architect extensions that use the International Electrotechnical Commission's Common Information Model (IEC CIM) to guide message and service definitions.

Smarter city data model standards landscape, Part 2: Transportation
In this series, learn about data model standards for smarter cities. Information exchange is challenging among city agencies, regardless of city size. The proliferation of different vendor solutions deployed across agency and departmental boundaries is the root of the problem. The solution is defining a common, standards-based smarter city data model that determines how information is structured and what it represents on a semantic level. This article focuses on the core concepts and standards that are common in the smarter city transportation domain.

Toward a Basic Profile for Linked Data
W3C defines a wide range of standards for the Semantic Web and Linked Data suitable for many possible use cases. While using Linked Data as an application integration technology in the Application Lifecycle Management (ALM) domain, IBM has found that there are often several possible ways of applying the existing standards, yet little guidance is provided on how to combine them. This article explains motivating background information and a proposal for a Basic Profile for Linked Data.

Case study of model-based systems engineering (MBSE): Part 1. The centralized systems model of IBM Rational Harmony
Modeling has been an important part of systems engineering since its inception. During the last decade, engineers have significantly increased their use of model-based technologies to evolve a new discipline of Model-Based Systems Engineering (MBSE). This discipline differs from traditional systems engineering in that it emphasizes a central system model that captures both system requirements as well as the design decisions that fulfill them. In addition to serving as a knowledge repository for systems engineering work artifacts, the system model can also be simulated to validate cost or performance studies and design choices. Highly practiced MBSE processes like IBM Rational Harmony for Systems Engineers focus on system functional analysis, which is the translation of functional requirements into a coherent description of system operations. The system operations are then used to derive ports and interfaces among the allocated system architecture blocks. These interfaces form the basis of the formal hand-off among various sub-systems.

Case study of model-based systems engineering (MBSE): Part 2. Develop data-focused processes for distributed systems analysis and design
Distributed systems are inherently data-oriented, with data entities dictating the sub-system boundaries and specific data interaction that defines the dynamic characteristic of a system. The focus on data entities and their behavior in distributed environments cannot be undermined. Thus the derivation of ports and interfaces (data interactions and attributes) being a consequence of functional analysis in a typical MBSE workflow, such as the IBM Rational Harmony systems engineering process seems an oddity in such a case. In this article, we explore how to develop an MBSE process suited for analysis and design of distributed systems.

Generate design work products from models
Outdated design work products are a big challenge in development and maintenance phase. This article shows how we can generate design work products from IBM Rational Software Architect design models by using Eclipse provided Business Intelligence and Reporting Tools (BIRT). This allows the modeling team to focus more on designing the models rather than producing the work products. The generation of work products is as easy as clicking a button, once the BIRT report has been authored.

A practical guide to developing enterprise architecture
To develop a useful enterprise architecture (EA) it is important to first understand the questions you want to answer with your architecture. Then based on these questions, you can develop an approach and identify the models that you need. Finally, you can do both quantitative and qualitative analysis on your architecture to either see where the business can be improved or identify necessary changes or enhancements to the architecture. This article offers a summary of an enterprise architecture program and its processes.

Define application architectures with Rational Software Architect: Part 2: Iteratively refine the architecture
This series presents techniques for creating models to specify and communicate the architecture of software-intensive systems. It illustrates the elaboration of the Online Catering architecture for a fictional company, Yummy Inc. Using an iterative approach, it describes the key architectural activities that are necessary to specify a software-intensive system with IBM Rational Software Architect. Part 1 of the series explained how to create a vision for the architecture during early stages of your project. In part 2, we describe how the architecture is iteratively refined using Rational Software Architect. Both articles assume that readers are familiar with methodologies based on iterative development.
