[@48mantusubudhi72]

if we are using fetchType as Eager then the N+1 problem should be fixed right . at the end we are dealing with object creation of realted tables .why do we need so much complications then ?

[@CodeDecode]

Performance is the reason people in It world moves towards lazy loading.

how is the {"listOfEmployees"} referred to Employee table?

[@CodeDecode]

List of employees is actually a list employee entity. Entity maps to relational table. Employee is actually a table in sql
