With the implementation of Intelligent Transportation Systems (ITS) for system management purposes, there is now the ability to extract archived data that can be used to evaluate the implementation of new operational strategies. In recognition of the need to provide feedback to decision-makers, efforts are underway to provide rigorous documentation of ITS benefits and costs. The objective of th...

Distributed data management at LHC scales is a staggering task, accompanied by equally challenging practical management issues with storage systems and widearea networks. CMS data transfer management system, PhEDEx, is designed to handle this task with minimum operator effort, automating the workflows from large scale distribution of HEP experiment datasets down to reliable and scalable transfe...

XML is here as the internet standard for information exchange among e-businesses and applications. With its dramatic adoption and its ability to model structured, unstructured and semi-structured data, XML has the potential of becoming the data model for internet data. In the recent years, Oracle has evolved its DBMS to support complex, structured, and un-structured data. Oracle has now extende...

Scientific research activities generate a large amount of data, which varies in format, volume, structure and ownership. Although there are revision control systems and databases developed for data archiving, the traditional data management methods are not suitable for HighPerformance Computing (HPC) systems. The files in such systems do not have semantic annotations and cannot be archived and ...

Todays data stream management systems (DSMSs) lack security functionality. Based on adversary scenarios we show how a DSMS architecture can be protected. We sketch a general DSMS architecture and introduce security issues that need to be considered. To face the threats we develop an extended system architecture that provides the necessary security mechanisms. We descuss the chosen concepts and ...

Most e-Learning platforms implemented in educational institutes provides a tool for instructors to enter the grades and for students to view them. This tool with the appropriate workflow is considered one of the most sensitive and important applications in any University Information Management System. Consequently, implementing this tool should consider the fact that it must be flexible and ada...
