MadeEasy Test Series: Databases - Er Diagram
Consider The Following Schema:- The minimum number of tables needed to represent E1 , E2and E3 are ______ Soln. According to me Answer should be 2 because We can merge 1. R1 and E2 in one Relation 2. E1,R2,E3 in one because its total participation on both the sides. So total 2 Tables Should be Enough.
