GDB_FALL 2013 Dated: Feb 14, 14

Dear Students!

Please Note that GDB of CS403 will be launched on 19th of February 2014 (19-Feb-2014) and will last for 48 hours only.

The topic will be as follows:

Suppose there are two entities "building" and "apartment". The entity "apartment" is dependent entity and cannot exist independently and “building” is an independent entity. The "apartment" entity contains the primary key (building_name) of building entity to identify the apartment of that specific building. The "apartment" entity also has its own identifier, i.e. apartment_no but that identifier is not sufficient to identify the particular apartment, so in this case we used both keys building_name and apartment_no to identify the particular apartment.

 

You have studied different dependencies in the course. You are required to choose the appropriate dependency applicable in  the above scenario. Justify your answer with reasons.

Try to provide precise, to the point answer and avoid irrelevant details.

what you say about trival dependency?

wht are the reason behind this???? trival depndncy ko define krein with rezn 

A trivial functional dependency occurs when you describe a functional dependency of an attribute on a collection of attributes that includes the original attribute. For example, "{A, B} -> B" is a trivial functional dependency, as is "{name, SSN} -> SSN". This type of functional dependency is called trivial because it can be derived from common sense. It is obvious that if you already know the value of B, then the value of B can be uniquely determined by that knowledge.

Transitivity:

if A --> B and B --> C Then A --> C

it is just like as

if A=B=C then A=C

i have submitted the functional dependency my final answer
