Simplify the following query: SELECT ENAME, PNAME FROM EMP, ASG, PROJ WHERE (DUR > 12 OR RESP = "Analyst") AND EMP.ENO = ASG.ENO AND (TITLE = "Elect. Eng." OR ASG.PNO 12 OR RESP NOT= "Analyst") AND...

Simplify the following query:

 SELECT ENAME, PNAME

 FROM EMP, ASG, PROJ

 WHERE (DUR > 12 OR RESP = "Analyst")

 AND EMP.ENO = ASG.ENO

AND (TITLE = "Elect. Eng." OR ASG.PNO <>

AND (DUR > 12 OR RESP NOT= "Analyst")

AND ASG.PNO = PROJ.PNO

 Also transform it into an optimized operator tree using the restructuring algorithm where select and project operations are applied as soon as possible to reduce the size of intermediate relations.
