To　analyze　large　quantity　of　information　in　medication　with　scientific　technique　and　to　provide　decision　supports　for　doctors,　we　set　up　the　research　on　Adverse　Drug　Reactions　(ADRs)　by　constructing　a　multidimensional　data　warehouse.　Adopted　SQL　Server　2005　business　intelligence　tools,　we　extracted,　transformed　and　loaded　the　data　from　spontaneous　reporting　system　(SRSs)　of　ADRs　to　the　data　warehouse,　and　realized　online　slice　analysis.　The　result　showed　that　in　this　way　we　could　ADRs　from　different　views,　which　provided　a　new　way　for　analyzing　and　evaluating　adverse　drug　reaction.　©　2012　IEEE.
