Hi I am new to postgresql
my immediate need is to be able to receive data form a live feed and analyze it as it accumulate and trend through out
theday I am trying to predict data direction so I need to be able to compare most recently received data to prior data
points. Is that posible with postgresql. If yes could you breifly describe how that can be accomplished. Now the
comparisonitself doesn't have to be done with database queries I am using R and sql to accomplish the analysis.
