Self Doubt on ER diagram
How to solve these type of questions https://gateoverflow.in/201404/er-diagram Copying the image for quick reference: Minimum no of tables. My approach was: First allocate all the relationships to entities (i.e decide on relationships) So here R5 goes with E4 , R4 ... tables will be E1R1E2R2, E4R5, E3R4, R3. Correct me if I'm wrong. Let me know if there is a better process.

Notice that we can always map 1:1 or l:N relationships in a manner similar M:N to relationships by using the cross-reference (relationship relation) approach, as we discussed earlier. This alternative is particularly useful when few relationship instances exist, in ... the entities or only those who are participating in relationship TO AVOID NULLS ex: Table 1 or table how will it be ?
