These modules can be any kind of file visualized by a browser: pictures, html files, audio files, animations files and other types of files visualized via a plug-in, like executable programs (CGI), applets and queries to databases. The user through an interface very similar to the Windows Explorer selects these modules. Then, these modules, following the object-oriented paradigm, are related basically in part-of relations (containment relationships, like regions on a map) or some of them - simpler - are taken as attributes of more complex ones. All the user needs to operate DISI2E are http (hyper text transfer protocol) servers - to publish the distributed information - and browsers, enabling users to navigate through the distributed system visualizing non-structured information, querying databases and executing programs.  aDatabase  aDistributed information system  aEnvironmental  aHypertext  aObject associations1 aFARIAS, O.
