Real-time transliteration using InfoSphere Streams custom Java operator and ICU4J
With the ever growing importance of Internet monitoring and sentiment analysis, there is an immediate need for identifying patterns (performing text analytics) in big data. However, one of the challenges during this exercise is that countries can have multiple languages that creates a challenge for effectively running the text analytics, since rules are not available for all the languages. For example, in India, the official language of each state is different and data is available in both English and local languages. This article describes how to bring about consistency during the transliteration process, and to use IBM InfoSphere Streams to prepare linguistic data and apply text analytics or pattern recognition logic.

Sybase to DB2 migration, Part 1: Process and methodology
Information assets are key to day-to-day business. They are also a huge source of institutional value and intellectual property that must be preserved, extended, and re-purposed as the systems underpinning them change. Given the current business environment, migration has taken on strategic importance for a number of reasons. The benefits of rationalizing processes and systems hinges on outcomes where services and functionality are as good or better than before, while free of costly redundancies or unnecessarily diverse technologies. Poorly executed migrations diminish these returns and fail to meet the "as good as or better than before" criteria.

Real-time data representation conversion in a distributed deployment using InfoSphere Streams native functions
InfoSphere Streams provides the capabilities for handling/reporting data or events as they happen in real time. But sometimes when running a distributed application on multiple platforms where data flows between machines having different processor architectures, the task can be challenging. Due to variations in processor architectures, the data representation may differ, requiring the application developer to convert the representation before applying the required logic. This is true especially if the data is in binary format. By performing data format conversion at real time, soon after data is read from source, more consistent and meaningful results can be obtained.

Accelerate Hibernate and iBATIS applications using pureQuery, Part 2: Using the IBM Integration Module for iBATIS and pureQuery
When extended with the downloadable IBM Integration Module, the IBM Optim pureQuery Runtime simplifies the process of generating DB2 static SQL for Hibernate and iBATIS applications. It does this without requiring you to make changes to your application code or to gather SQL from production workloads. The Optim pureQuery Runtime also enables Hibernate and iBATIS applications that access DB2 or Informix to benefit from the heterogeneous batching feature in pureQuery. With the heterogeneous batching feature, you can batch multiple INSERT, UPDATE, and DELETE requests before sending them across the network, even when the requests reference multiple tables. This article is part two of a two-part series. It describes using the IBM Integration Module with iBATIS applications. This article includes a downloadable sample application that illustrates how you can easily enable static SQL and heterogeneous batch functions with iBATIS applications. Part one of the series focuses on Hibernate applications.
