|GDB_FALL 2013||Dated: Feb 14, 14|
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.

i cant understand what to describe? GDB mein to answer conciseness sy dena hy aur yeh dependencies ko alag alag define krna hy yaa kisi aik ka batana hy? please help to understand the Q.
u need to tell with reasons that which dependency is best for the given situation. no definitions
i think Identifier Dependency is correct answer!
identifier dependency means in case of existence dependency dependent entity "apartment" does not have its own identifier. in this case it does have identifier so we cant use it.
depndency ka name batana nai konsi gvn scenario pe aplicable hai with logical reasn
yahn to functional dependency ka hi zikr ho rha hy aur suitable kon si hy?
fucntional corect hai
