Efficient indexing, search and analysis of event streams; EventCloud: exploration and analysis tool for events

Abstract

Today's business is event-driven. Businesses of all shapes and sizes are driven by and respond to events. Thus IT-Systems offer a large amount of events, representing notable activities in complex workflows and business processes, that are the subject of event analysis. This thesis highlights the necessity for specialized event analysis tools, explains the relationship to Complex Event Processing (CEP), outlines requirements and proposes the EventCloud system.<br />EventCloud is a generic, offline event analysis tool for Complex Event Processing (CEP) scenarios. EventCloud enables its user to navigate through events, pick up single events and display their content, discover chains of events and how they are correlated, and to recognize patterns inside the events. Metrics can be defined to provide insight at a higher level and to measure business performance. It visualizes business and process developments at the fine-grained level of events.<br />
