Regulating access to electronically stored personal information is an increasingly challenging task and significant concerns about the privacy of personal data have emerged. These concerns are fueled, in part, by the ever-growing number of highly-publicized security incidents involving data theft and privacy violations. As the most recent example, UC Berkeley has discovered that foreign attacke...

Base Class Library (BCL)-An object oriented framework of reusable classes accessible from any .NET language Binary file-A file containing information that is in machine-readable form that can only be interpreted by a program that understands in advance exactly how it is formatted. Binary object – A binary large object (BLOB) is a format of binary data stored in a relational database. Business v...

When data requirements change and the existing database structure no longer reflects the current state of the Universe of Discourse, transformation of the information system is inevitable. Although required changes usually involve the addition or deletion of Information, part of the process can be considered rule-changing but information-preserving. This part of the transformation process, i.e....

Monitoring alpine glacier change has many practical and scientific benefits, including yielding information on glacier-fed water supplies, glacier-associated natural hazards, and climate variability. This paper describes the design and implementation of a spatio-temporal GIS database for monitoring glacier geometry and geometric change. The temporal component of the glacier data is managed thro...

If overview, zoom, filter, and details are sufficiently important to make them the mantra of Information Visualization [Shneiderman 1996], why aren't they first class objects in InfoVis systems? Why not specify what the overview is of, perform set operations on filters, and annotate details with usage information? While these have all been implemented as one-off features, this paper outlines te...

Video-on-Demand systems have received a good deal of attention recently. Few studies, however, have addressed the problem of locating a video of interest in a large video database. This paper describes the design and implementation of a metadata database and query interface that attempts to solve this information retrieval problem. Sample queries were collected by interviewing a variety of user...

Our research organization has been constructing a large scale database named SHACHI by collecting detailed meta information on language resources (LRs) in Asia and Western countries. The metadata database contains more than 2,000 compiled LRs such as corpora, dictionaries, thesauruses and lexicons, forming a large scale metadata of LRs archive. Its metadata, an extended version of OLAC metadata...

Several Geographic Information Systems (GIS)-based Karst Feature Databases (KFDs) have been established in many karst regions and countries (Cooper et al., 2001; Florea et al., 2002; Lei et al., 2001). However, the absence of comprehensive database models and standard metadata impeded the data compatibility and management (Gao et al., 2005a). A KFD has been developed in Minnesota in the past fe...
