A proposal for the digital storage and sharing of remotely sensed archaeological data

Currently Internet is one of the instruments more effective than transmission of the data and seems to set off to become one of the channels privileges of information’s diffusion. Through outline of standard communication, its architecture guarantees the compatibility of dialogue between the different site that they shape the net, concurring the sharing of experiences, services, computer science resources and exceeding the physical distance between the customers. The knowledge of the enormous potentialities of Internet has capacities to develop a plan to us that previews the realization of an informative system in net based on a DBMS (Data Base Management System), that is, a distributed system that it allows to record, to update and to extract information from a database of vertical air photographs of the Tuscany, managed from an interactive graphical interface. The DBMS is already, for its nature, an instrument that considers the data like one on hand common resource of an organization of various customers, satisfying in this way the more and more obvious requirement of spreading and sharing of the acquaintances. Indispensable property of every DBMS are, in fact:  the recording, the organization and the management of the data, according to criteria that answer directly to the necessities of the context in which it is developed.  the spread and the sharing - the customers must be able to approach to one data bank that can be consulted second opportune modalities  the reliability, therefore the system capacity to conserve the content of the DBMS through rescue functions and restoration.  the privacy, guaranteed through mechanisms of authorization and shapes of control. It must be, moreover, efficient, that is necessarily able to carry out the operations employing with of resources - space and time - permissible for all the customers, and effective, in a position to rendering the activities of the customers productive. A DBMS is substantially one layer software that insert between the true and own customer and data. Thanks to this intermediate layer the customer and the applications not approach the data therefore as they are registered effectively, that is to their physical representation, but of it they see only one logical representation. That allows to an elevated degree of independence between the applications and the physical memorization of the data. Thanks to these characteristics the applications that are developed can count on one sure, reliable and generally scalable source given. Such property are favorable for applications that use Internet like infrastructure and that they have therefore obvious problems of emergency and scalability. The choice of to insert the DBMS in the net has been, moreover, encouraged from the opportunity to widen in considerable way its attitude to the transmission and usability of the information. The net is a system that puts on hand of the public, in the tightest times, the various acquaintances and therefore allows to consult the documentation and to render it object of critics and interpretations; moreover simple and immediate verification gives to the protection organs the advantage of one. The insertion of the data bank in Internet admits, moreover, the access to the information to a net of customers is capillary diffused in the territory, extending the spreading of the knowledge also to who is not one specialist in the archaeological field. It allows, moreover, the 'popolamento' of the DBMS in real time from not fixed emplacements and you dislocate in various points; concurring the different breaking in experiences in the same data bank, rendering them immediately that can be consulted, and accelerating the process of communication and exchange of the acquaintance.
