Lofar Survey workshop 8/3/2007 AstroWise paradigm “Classical” paradigm Forward chaining Target processing - Awe Backward chaining waterfall model TIER architecture User hunts upstream driven by input raw data Driven by query of user Process in pipeline workflow Process in bits and pieces on the fly Backward chaining Operators push data User pulls data Results in releases Provide information system Static archives – publish Dynamic archives –publish Internet Raw data - obsolete Raw data is sacred
