The Clustering Database has been realized on the basis of Clustering model of EFFECTIVE that was created in the first part of the project. The design of the database took into account the following aspects: - Characterization of the main elements of the Clustering Model (Projects, Partners and Exploitable results) in a way that was coherent both with the functionalities of the model itself (identifying clustering opportunities mostly) and with the structure of existing database insisting on these contents (such as the SygMA EC portal or the Innovation Portal); - Definition of auxiliary “data structures” needed to fill in with details the main abovementioned elements; - Creation of relations among tables of the database; - Definition of a “sequence” for filling with data the DB itself, only partially through the project evolution but mostly in case of a following implementation; - Initial validation and refinement of the DB with “test data” manually inserted in tables
