On-demand data warehousing systems (DWHs) naturally imply a high quality of customized solutions for each individual, where customized business requirements can be facilitated. Therefore, on-demand DWHs have to increasingly deal with the autonomous data changes and schema changes due to continually evolving users' requirements. In fact, DWHs have to be update according to different types of evolution of information sources to reflect the real world subject to analysis. The thesis outlines our investigation focusing on a methodology that can cope with the variety of business requirements in the context of on-demand DWHs. We discuss our plans to address these problems bridging the semantic gap between the requirements, the components and the architecture design of current DWH systems. Overcoming these challenges will facilitate effective tracing of requirements which implies the impacts upon the architectural design and thus increase usability of DWHs for end users.

The Event-Driven Process Chain (EPC) is designed for modelling business processes, but does not yet include any means for measuring the performance of a business process. Thus, we extend the metamodel of the EPC with performance measures to make them conceptually visible. The extensions are tested with an example business process. Copyright 2007 ACM.

This demo introduces Eventifier, a tool that helps in reconstructing an event log from operational databases upon which process instances have been executed. The purpose of reconstructing such event log is that of discovering process models out of it, and, hence, the tool targets researches and practitioners interested in process mining. The aim of this demo is to convey to the participants both the conceptual and practical implications of identifying and extracting process execution events from such databases for reconstructing ready-to-use event logs for process discovery.
