Please include the following in the solution: normalization (into CNF), query analysis (type incorrect; semantics incorrect), connection graph, join graph, redundancy elimination, rewriting using transformation rules and include the operator tree.
1. Simplify the following query: SELECT FROM WHERE ENAME EMP, PROJ, ASG EMP.ENO = ASG.ENO AND ASG.PNO = PROJ.PNO AND (DAY == 'Wednesday OR NOT (DAY != 'Wednesday' AND ENAME == 'Fred')) AND NOT (DAY != 'Wednesday' AND PNAME == = Billing') OR NOT(DAY == 'Wednesday' OR ENAME != 'Fred)
