The usability of remote controls for home entertainment systems like TV sets, set-top boxes, satellite receivers and home entertainment centers has reached overstraining complexity: about eight to ten remote controls with about sixty to eighty push-buttons each are typical for a home entertainment system setting today. To be able to harness the ever growing(More)
The REA business model language is an established vehicle (i) to model businesses in terms of domain specific value chains and their key concepts and (ii) to capture business data in terms of accounting artefacts. REA has evolved into a specification that could drive web shops, enterprise/trading information systems, enterprise resource planning systems,(More)

Building on top of well established academic findings and proposals regarding the REA model we are proposing a software model building(More)
