Through the digital survey and the use of specialized software, the elements and the relations of contemporary are made accessible to an increasingly knowledgeable and demanding public. Digital databases, wherein the acquired information is collected, increasingly require the development of narrative systems for the use of information and the preservation of memory. Some experimental research explain how the “migration” of the reality in virtual environment strongly depends on the structure of a design database that tries to reproduce the real space and the structure of the relations during the visit of the place. In the digital space, the user can interface with the structural elements of the database to develop critical analysis models.
