Real-time has become one of the crucial characteristics of modern applications and is completely changing the game in the data processing. Due to its capability to support continual monitoring, real-time data processing has become a very important mechanism in many application areas: traffic management, logistics, eHealth, smart grids, to name but a few. In this talk we present technologies to deal with real-time data on-the-fly, challenges and possible solutions to deal with these challenges such as using Web-friendly standards to create open and extensible systems for real-time data.
