Integration of trusted information is an important requirement from business application. As business applications adaption relies on sensor data, that information must be trustworthy enough in order to prevent any misuse of sensor data. For example, the use of un-trustworthy information in healthcare system can have severe consequence on patient life. But it appears that sensors are not tamper...

Business intelligence systems are becoming a growing trend on the market nowadays. Reason for this is the increasing amount of information generated and collected within the company and from many external sources. In order to remain competitive on the market, it is very important to collect and select relevant information in time, from which a business decision can be made. OLAP (On Line Analyt...

With access to real-time information on critical performance indicators of business processes, managers and staff members can play a crucial role in improving the speed and effectiveness of an organization’s business operations. While the investments in data warehouse technologies have resulted in considerable information processing efficiencies for the organizations, there is still a significa...

L. Zeng H. Lei T. Koyanagi H. Ohsaki H. Chang Business event processing requires efficiently processing live events, computing business performance metrics, detecting business situations, and providing real-time visibility of key performance indicators. Given the high volume of events and significant complexity of computation, system performance event throughput is critical. In this paper, we a...

TeNDaX is a collaborative database-based real-time editor system. TeNDaX is a new approach for word-processing in which documents (i.e. content and structure, tables, images etc.) are stored in a database in a semi-structured way. This supports the provision of collaborative editing and layout, undoand redo operations, business process definition and execution within documents, security, and aw...

Online data or streaming data are getting more and more important for enterprise information systems, e.g. by integrating sensor data and workflows. The continuous flow of data provided e.g. by sensors requires new workflow models addressing the data perspective of these applications, since continuous data is potentially infinite while business process instances are always finite. In this paper...

In applications field such as business activity monitoring, telecommunications data management, web personalization and sensor networks event takes the form of continuous event streams. Clients require to sense situations and exceptions in these continuous event stream as opposed to one-time queries to a database. Our research is focused on the following real-time event processing issues: compl...

Aggregate functions are particularly useful when dealing with extremely large volumes of data. In business and statistical databases, aggregate queries have been leveraged by powerful methods such as On-Line Analytical Processing (OLAP). In contrast, current technology for raster image databases is lagging behind. A comparative study between raster image and business databases has shown similar...
