    Consistency Models for Cloud-Based Online Games: The Storage System's Perspective

    The existing architecture for Massively Multiplayer Online Role-Playing Games (MMORPG) based on RDBMS limits the availability and scalability. With increasing numbers of players, the storage systems become bottlenecks. Although a cloud-based architecture has the ability to solve these specific issues, the support for data consistency becomes a new open issue....

    Developing a Cloud Provider Selection Model

    Recently, a growing development and use of Cloud computing services has been observed. Especially modeling cross-organizational cooperation and the respective provider comparison are gaining importance. Despite initial positive results, it is challenging in theory and practice to find an appropriate provider matching the individual requirements. Moreover, the comparison process is...

    Workload-Based Heuristics for Evaluation of Physical Database Architectures

    Database systems are widely used in different application domains. Therefore, it is difficult to decide which database management system meets the requirements of a certain application at most. This observation is also true for scientific and statistical data management, due to new application and research fields. New requirements are often...

    Self-Tuning Distribution of DB-Operations on Hybrid CPU/GPU Platforms

    A current research trend focuses on accelerating database operations with the help of GPUs (Graphics Processing Units). Since GPU algorithms are not necessarily faster than their CPU counterparts, it is important to use them only if they outperform their CPU counterparts. In this paper, the authors address this problem by...

    Illustration Watermarking: A Novel Concept for Dissemination of e-Learning

    Demand on permanent availability and fast access to learning material competes with the reluctance to new and maybe unconventional concepts as well as the belief in traditional and familiar learning methods. In this paper, the authors propose an approach for combining learning content and learning media inseparably. Their solution depends...

    Post Execution Analysis of Business Processes: Taxonomy and Challenges

    Business process modeling is used for better understanding and communication. Mostly, business process modeling is discussed from information system development perspective. After execution of business processes, various objects become important and have to be represented in business process models. The process models conceived for information system development are not sufficient...

    Investigation of Graph Mining for Business Processes

    Business process management and business intelligence are fields which gain a lot of attention in recent years. These techniques try to improve not only efficiency of processes but also save considerable cost. Graph based representation of concepts (objects, data) are also used in business domain to support aforementioned techniques. Graph...

    Accepting Hybrid Networks of Evolutionary Processors with Special Topologies and Small Communication

    Starting from the fact that complete Accepting Hybrid Networks of Evolutionary Processors (AHNEP) allow much communication between the nodes and are far from network structures used in practice, the authors propose in this paper, three network topologies that restrict the communication: star networks, ring networks, and grid networks. They show...

    Self-Tuning of Data Allocation and Storage Management: Advantages and Implications

    Many important business applications use complex Database Management Systems (DBMS). These DBMS have to be administrated and optimized for an optimal performance, especially in time-critical applications. Administration and optimization are very complex and costly tasks. Therefore, researchers and DBMS vendors focus on development of self-tuning techniques for a continuous adaption,...
