    Hi Juergen,

    Firstly, thanks for the great articles.  I think that a more structure framework for BI has been a long time in coming.

    I have a question about the propagation layer and the corporate memory.  Please could you explain a little more why the corporate memory is necessary.  Normally, when extracting, one would keep all history in the propagation layer, which seems to render the corporate memory redundant.  Are you suggesting that the data in the propagation layer can be deleted once it has been propagated?

    Or, is it that one should only store that data that is required (e.g. just the key figures that are relevant at the relevant granularity) for propagation in the propagation layer?

    Thanks!
