Most any journalism professor, upon mention of Wikipedia, will immediately launch into a rant about how the massively collaborative online encyclopedia can't be trusted. It can, you see, be edited and altered by absolutely anyone at any moment.
But how much less trustworthy is the site for breaking news than the plethora of blogs and other online news sources?
A key component of a company's IT framework is a business intelligence (BI) system. Traditional BI systems were designed for senior management and business analysts to report on, analyze and optimize business operations to reduce costs and increase revenues. Organizations use BI for strategic and tactical decision making where the decision-making cycle may span a time period of several weeks or months. Competitive pressures coming from a very dynamic business environment are forcing companies to react faster to changing business conditions and customer requirements. As a result, there is now a need to use BI to help drive and optimize business operations on a daily basis, and, in some cases, even for intraday decision making. This type of BI is called operational business intelligence and real-time business intelligence and it is used not only by senior management and analysts (as in traditional BI) but also by line of business managers and operational users. In other words this is BI for everyone.
Nondeterministic pauses in traditional garbage collection (GC) have inhibited Java technology from being a suitable environment for real-time (RT) development. Metronome GC -- part of IBM WebSphere Real Time -- provides deterministic GC behavior that, when combined with other features, enables developers to write hard RT applications in the Java language. The authors describe the approach that Metronome uses for deterministic GC, technical issues involved in developing Metronome, and the tools and facilities available for tuning GC.
