Towards workload-aware self-management: Predicting significant workload shifts
Found in: Data Engineering Workshops, 22nd International Conference on
By Marc Holze, Ali Haschimi, Norbert Ritter
Issue Date:March 2010
pp. 111-116
The workloads of enterprise DBS often show periodic patterns, e.g. because there are mainly OLTP transactions during day-time and analysis operations at night. However, current DBS self-management functions do not consider these periodic patterns in their ...
 
Duplicate detection in probabilistic data
Found in: Data Engineering Workshops, 22nd International Conference on
By Fabian Panse, Maurice van Keulen, Ander de Keijzer, Norbert Ritter
Issue Date:March 2010
pp. 179-182
Collected data often contains uncertainties. Probabilistic databases have been proposed to manage uncertain data. To combine data from multiple autonomous probabilistic databases, an integration of probabilistic data has to be performed. Until now, however...
 
Rule-Based Coordination of Distributed Web Service Transactions
Found in: IEEE Transactions on Services Computing
By Michael von Riegen, Martin Husemann, Stefan Fink, Norbert Ritter
Publication Date: September 2009
pp. 60-72
Current approaches to transactional support of distributed processes in service-oriented environments are limited to scenarios where the participant initiating the process maintains a controlling position throughout the lifetime of the process. This constr...
 
Reliable Monitoring for Runtime Validation of Choreographies
Found in: Internet and Web Applications and Services, International Conference on
By Michael von Riegen, Norbert Ritter
Issue Date:May 2009
pp. 310-315
Cross-organizational business processes gain more and more attention in the scientific community. For modeling these processes, choreographies are an adequate solution to describe the observable behavior for each business participant and the corresponding ...
 
Providing Decision Capabilities to Coordinators in Distributed Processes
Found in: Internet and Web Applications and Services, International Conference on
By Michael von Riegen, Martin Husemann, Norbert Ritter
Issue Date:June 2008
pp. 500-505
Current approaches to transactional support of distributed processes in service-oriented environments are limited to scenarios where the participant initiating the process maintains a controlling position throughout the lifetime of the process. This constr...
 
Transactional Coordination of Dynamic Processes in Service-Oriented Environments
Found in: Web Services, IEEE International Conference on
By Martin Husemann, Michael von Riegen, Norbert Ritter
Issue Date:July 2007
pp. 1024-1031
Service-oriented environments facilitate dynamic processes whose properties can be altered during runtime. The transactional support of such processes holds specific requirements that are not completely covered by existing specifications. In this paper, we...
 
Towards Integrated Query Processing for Object-Relational and XML Data Sources
Found in: Database Engineering and Applications Symposium, International
By Iryna Kozlova, Norbert Ritter, Olga Reimer
Issue Date:December 2006
pp. 295-300
The recently increased amount of information stored in XML format has lead to the development and wide deployment of so-called native XML database management systems (XML DBMS). In parallel, (object-)relational DBMS remain well known, approved and widely u...
 
Enriched Relationship Processing in Object-Relational Database Management Systems
Found in: Cooperative Database Systems for Advanced Applications, International Symposium on
By Nan Zhang, Norbert Ritter, Theo Härder
Issue Date:April 2001
pp. 50
In this paper, we bring together two important topics of current database research: enhancing the data model by refined relationship semantics and exploiting ORDBMS extensibility to equip the system with new functionality. Regarding the first topic, we int...
 
iWebDB - Web Site Administration Based on Object-Relational Database Technology
Found in: Database Engineering and Applications Symposium, International
By Henrik Loeser, Norbert Ritter
Issue Date:August 1999
pp. 92
Since the emergence of the World Wide Web in the year 1990, the number of accessible Web servers, HTML pages, and, thereby, the amount of accessible data have increased dramatically. Consequently, many people around the world are engaged in maintaining a W...
 
Design Management in CONCORD: Combining Transaction Management, Workflow Management and Cooperation Control
Found in: Research Issues in Data Engineering, International Workshop on
By Bernhard Mitschang, Theo Haerder, Norbert Ritter
Issue Date:February 1996
pp. 160
In this paper, we want to define design management as an encompassing task supporting cooperative design processes entirely. In our opinion, this requirement can best be fulfilled by exploiting concepts from transaction management, workflow management and ...
 
Orestes: A scalable Database-as-a-Service architecture for low latency
Found in: 2014 IEEE 30th International Conference on Data Engineering Workshops (ICDEW)
By Felix Gessert,Florian Bucklers,Norbert Ritter
Issue Date:March 2014
pp. 215-222
Today, the applicability of database systems in cloud environments is considerably restricted because of three major problems: I) high network latencies for remote/mobile clients, II) lack of elastic horizontal scalability mechanisms, and III) missing abst...
   
Consistent on-line classification of dbs workload events
Found in: Proceeding of the 18th ACM conference on Information and knowledge management (CIKM '09)
By Claas Gaidies, Marc Holze, Norbert Ritter
Issue Date:November 2009
pp. 1641-1644
An important goal of self-managing databases is the autonomic adaptation of the database configuration to evolving workloads. However, the diversity of SQL statements in real-world workloads typically causes the required analysis overhead to be prohibitive...
     
Group-authoring in CONCORD&emdash;A DB-based approach
Found in: Proceedings of the 1997 ACM symposium on Applied computing (SAC '97)
By Norbert Ritter
Issue Date:April 1997
pp. 158-165
This paper describes the effects of program restructuring in a dataflow environment. Previous studies showed that dataflow programs can exhibit locality and that a memory hierarchy is feasible in a dataflow environment. This study shows that the order in w...
