N2  - A growing number of enterprises use complex event processing for monitoring and controlling their operations, while business process models are used to document working procedures. In this work, we propose a comprehensive method for complex event processing optimization using business process models. Our proposed method is based on the extraction of behaviorial constraints that are used, in turn, to rewrite patterns for event detection, and select and transform execution plans. We offer a set of rewriting rules that is shown to be complete with respect to the all, seq, and any patterns. The effectiveness of our method is demonstrated in an experimental evaluation with a large number of processes from an insurance company. We illustrate that the proposed optimization leads to significant savings in query processing. By integrating the optimization in state-of-the-art systems for event pattern matching, we demonstrate that these savings materialize in different technical infrastructures and can be combined with existing optimization techniques.

JF  - Public Administration in Germany
N2  - The international community of public administration and administrative sciences shows a great interest in the basic features of the German administrative system. The German public administration with its formative decentralisation (called: administrative federalism) is regarded as a prime example of multilevel governance and strong local self-government. Furthermore, over the past decades, the traditional profile of the German administrative system has significantly been reshaped and remoulded through reforms, processes of modernisation and the transformation process in East Germany. Studies on the German administrative system should focus especially on

    key institutional features of public administration;

    changing relationships between public administration, society and the private sector;

    administrative reforms at different levels of the federal system; and

    new challenges and modernisation approaches, such as digitalisation, open government and better regulation.
