I couldn't agree more - as the MER mission went into double overtime, 
and the number of data products began to strain things, our metadatabase 
really began to slow down. Consider individual queries taking on the 
order of several seconds in the worst case. After configuring the 
materialized views, the DB access times went down to around .1 seconds.
