Tool and die makerTool and die makers are highly skilled crafters working in the manufacturing industries. Variations on the name include tool maker, toolmaker, die maker, diemaker, mold maker, moldmaker or tool jig and die-maker depending on which area of concentration or industry an individual works in. Tool and die makers work primarily in toolroom environments—sometimes literally in one room but more often in an environment with flexible, semipermeable boundaries from production work.
Systems designSystems design interfaces, and data for an electronic control system to satisfy specified requirements. System design could be seen as the application of system theory to product development. There is some overlap with the disciplines of system analysis, system architecture and system engineering. If the broader topic of product development "blends the perspective of marketing, design, and manufacturing into a single approach to product development," then design is the act of taking the marketing information and creating the design of the product to be manufactured.
Trait (programmation)Un trait est une sous-classe abstraite, un modèle conceptuel pour structurer des programmes orientés objets. C'est un ensemble de méthodes concrètes ou fonctions, pouvant être ajouté à une classe pour étendre ses fonctionnalités. Quand un langage de programmation supporte les traits, il permet la résolution explicite des conflits qui apparaissent quand une classe utilise deux traits qui ont des méthodes qui portent le même nom (contrairement aux mixins).
