|What is the meaning of ID-dependent entity, & ID-independent entity please explain.|
|Raju Royal.Sp said: (Jul 3, 2013)|
ID means identifier so its full name is identifier -dependent entity.
Actually the given question is observed clearly which is identifies to the another entity that's why ID-dependent entity is the correct answer.

|It should be a weak entity.|

|ID-dependent entity: entity (child) whose Identifier depends (includes) another identifier.
For example, Building:Apartment -> for describing an apartment you need to include building name and all.
Weak Entity: existence depends on another entity.
Eg: Model: Car.
All Id-dependent entity are weak, and vice-versa is not true.
