This paper presents a platform that allows information management in mechatronics systems development process. The main problem focused is the material selection for a spare part of a mechatronic complex system. Within the O2M mechatronics project, a database and its access platform has been developed. This platform aims at understanding the process in which different specialists provide the designer with all the analyses, test and simulations required in order to select the best material. The paper focuses on the search capabilities of the platform.
