|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.
