A PDM system enables the management of the whole product data and related information about its entire lifecycle. The main goal of this paper is to highlight the added value of using an object-oriented approach for modelling, specifying and implementing a PDM system on a business case study. The chosen object-oriented approach and the used UML diagrams for the modelling and integration of product, process, and resource data is detailed for a turboprop aircraft project. # 2004 Elsevier B.V.
