world than your analytical model. If you see about a third or more of the your work getting implemented or used then consider yourself lucky. Notwithstanding analytic capabilities, analytic project get shelved for various reasons all the time, including, Data chan GED, problem changed, no one interested in solution, implementation too expensive, benefit don't worth the cost, someone ELS E did it first, and

manual optimization in the homework similarity matrix, we need to calculate the similarity of 22 documents, which is actually a matrix operation. 1) The code is as follows, spents 1m22.042sSelect X.docid,y.docid,sum (X.count*y.count) as Count from Frequency X, Frequency y where x.term = Y.term and X.docid 2) Submit the answer only need, one of the results, time 1m10.919s, you can see here is actually calculated the similarity of all documents intercepted, DB is not optimized.SELECT * FROM (sele
