A core concept in discussions about technological support for knowledge management is the Corporate Memory. A Corporate or Organizational Memory can be characterized as a comprehensive computer system which captures a company's accumulated know-how and other knowledge assets and makes them available to enhance the e ciency and e ectiveness of knowledge-intensive w ork processes. The successful development of such a system requires a careful analysis of established work practices and available information-technology IT infrastructure. This is essential for providing a cost-e ective solution which will be accepted by the users and can be evolved in the future. The current paper compares and summarizes our experiences from three case studies on Corporate Memories for supporting various aspects in the product life-cycles of three European corporations. Based on the conducted analyses and prototypical implementations, we sketch a general framework for the development methodology, architecture, and technical realization of a Corporate Memory.
Die Anellierungsreihe Naphthalin, Pyren, 1.12‐Benzperylen wird durch die Synthese der Kohlenwasserstoffe III, VIII und XI fortgesetzt. Die Spektren dieser Reihe werden verglichen mit denen der Reihe Benzol, Naphthalin, Chrysen, Picen. Der Kohlenwasserstoff I wird durch Kondensation von Pyren mit 1‐Bromnaphthalin und Aluminiumchlorid dargestellt. Mit Maleinsäureanhydrid wird daraus über die Dicarbonsäure II der Kohlenwasserstoff III dargestellt. 3.3'‐Dipyrenyl (V) aus 3‐Brompyren und Kupferpulver ist identisch mit einem bereits früher auf anderem Wege erhaltenen Produkt. Sein Ringschluß ergibt VI, daraus gewinnt man mit Maleinsäureanhydrid VII und durch Decarboxylierung VIII. Zweifache Kondensation von Pyren mit Bromnaphthalin gibt den blauen Kohlenwasserstoff IX, der zweimal Maleinsäureanhydrid zu X addiert, dessen Decarboxylierung XI liefert.
