Waldemar Kot, Oracle

is passionate about Java and middleware technologies. Waldek joined Oracle Polska as Principal Systems Engineer in 2008, following Oracle’s acquisition of BEA Systems. At Oracle his role is to advise customers in Eastern Europe about middleware technologies they use in application development and systems integration projects and solutions related to SOA, EDA and BPM. Waldek has extensive knowledge and experience with Java, J2EE/Java EE and Spring, but is also interested in technologies related to modern telecommunication, like IMS (IP Multimedia Subsystem), SIP, SIP Servlet or telecom web services. Waldek is also active participant of the ever-growing Java community in Poland and proud member of the Warszawa Java User Group.

Temat: Event processing technologies.

Sesja: Java

The session will cover some of the aspects of event processing, particularly related to event processing in distributed systems and systems’ integration. We will discuss (and also demonstrate in practice) middleware technologies supporting various stages of the event processing lifecycle (event creation, transportation, transformation, presentation, storing, etc.). Also, we will talk over various kinds of event processing offered by the technologies:

  • from simple event processing (e.g. through message-oriented middleware, like JMS - well-known from the J2EE/Java EE application servers)
  • to different forms of event mediation (for example by using ESB - Enterprise Service Bus or integration process engines)
  • to complex event processing, which is often characterized by necessity to process large amounts of events (even millions events per second) in real-time and which focuses on identifying complex patterns among events, correlations of streams of events, looking for trends and relationships between events like causality, advanced filtering and aggregation of events or performing complex streaming calculations for certain groups of events (e.g. by use of time- or length-based windows).

One of the main goals of the session is also to outline positioning and relationships between each of the components in bigger architecture of a system. The session is addressed to architects and designers of systems and integration solutions and developers as well as anybody interested SOA (Service Oriented Architecture), EDA (Event-driven Architecture) and middleware.

The technologies presented during the session are part of Oracle Fusion Middleware family of products, enriched with the solutions of BEA Systems, acquired by Oracle in 2008.
