to real-time database management systems to be used in such control-systems. By integrating a real-time database management system into a vehicle control-system‚ data management on a higher level of abstraction can be achieved. Current database management concepts are not sufficient for use in vehicles‚ and new concepts are necessary. A case-study at Volvo Construction Equipment Components AB in Eskilstuna‚ Sweden presented in this thesis‚ together with a survey of existing database platforms confirms
