Mission-critical web applications

Abstract

Large databases organized and offered online for remote accessing, integrated through meaningful links among data; " Freshly defined, working metaphors to map traditional methods into the new information technology environments. Interaction through an interface that (1) is user-friendly, offering easy interaction to general users who very often remain permanent novices with respect to the data accessed and the technologies used; (2) is user-centered, referring to the user's traditional paradigms and to his or her daily work This situation, in which many resources are available but can be exploited only with great difficulty, has motivated researchers and practitioners of automatic data management to look more closely at data mining and knowledge discovery in databases [1] and at collaborative approaches to both scientific discovery [20] and information exploration [16].We believe that successful and outstanding contributions require collaboration among researchers in different disciplines, each of whom has a different part to play in preparing a synergic mixture of

A review of intensity data banks online

“…This dataset was used to compile the parametric catalogue of damaging earthquakes in the Italian area, NT (Camassi and Stucchi, 1997), accounting for one thousand events. DOM was published over the Internet as an online searchable database in 1997, and progressively updated during the following two years (Padula and Rubbia Rinaldi, 1999) and it is presently run by INGV at http://emidius.mi.ingv.it/DOM/ DOM stores 37 000 intensity data points, referring to 904 earthquakes in the time window 1000-1980 and more than 10 000 localities, 935 intensity maps, and relies on 81 macroseismic studies.…”

Changes and challenges following the 1997 Colfiorito earthquake: the evolution of the use of the Internet for large seismic events

“…This website carried out the functions of requesting, gathering and processing in real time scientific and information contributions for the Internet, relative to the seismic sequence underway; it also had the function of publicising the materials provided by other web servers. Moreover, it also made available the seismicity data that were focused on the area of interest, using again the seismic databanks that had already been made available on-line as the deliverables from projects for Civil Protection, as described by (Padula and Rubbia Rinaldi, 1999 -Maximum observed intensities in the communities of Umbria-Marche from 1000 to 1980;…”

Cartography and GIS: extending collaborative tools to support virtual teams

“…A related environment, developed for collaborative work with historical seismological data, while not called a collaboratory by its designers, is another good example of the kind of distributed laboratory envisioned by Wulf. The goal of this environment (that supports collaborative space-time queries, queries of seismic zones, and generation of seismic intensity maps) is to construct and transfer knowledge in real time during a seismic crisis (Padula and Rinaldi, 1999).…”
