Is it possible to implement a parent-child relationship in the same
class..
for example

parent Location has a child Location...

for instance Mall class with fields name, longitude, latitude.
 a big mall            name X, lat - 1.1  long- 2.3
     sub mall          name A, lat - 1.01  long -2.1
         sub mall      name B
     sub mall
     sub mall
         submall
              sub mall
