 Suppose we have a table “Employee” having column “age” in it. The table “employee” might have a data of different age groups according to their designations. The employee at high levels of post like Project Manager, Managing director etc has different age group when we are comparing it with other junior or senior level employees.


You have studied various indexing techniques for random access and better organization of data. By having a context of above scenario; if you have given an option to choose one indexing technique from two below indexes, which you would like to choose that will help to get optimized results? 


§         Clustered index

§         Un-clustered/Non-clustered index


You have to choose only one technique out of the two and give valid reasons to support your answer.

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

its a cluster index

Rubab shear hi kar daen  plz

cluster kia ha ma ne

due to just age column

dae daen ma nae b abi karna hay ...

I would like to choose cluster index because the data is huge and in case of sorting and searching of data in indexed situation the time of sorting is large In cluster index i can group all the related data into one group e.g. at least equal age group join together and set them one primary key for one cluster so that in case of searching only that sort of group searched which contain equal or near to primary key.
