I've been bodging my way though setting up a database to hold summary info for 11 million assets with various look-up tables around it, the whole to be refreshed weekly. Its not that big - around 15Gb, it doesn't have a timestamp as the partition key and it does not contain transaction info, but when I look at the Oracle DW documentation, lo-and-behold - many of the concepts and techniques apply - bitmap indexes, partitioning, 'fact' and 'dimension' tables, ETT, etc. 'A rose by any other name would smell as sweet' -- David Lord
