Question 1                                                                                                                                         [10 Marks]

 

Consider the following table:

 

Player_Team

Player_ID

Player_Name

Team_ID

Pool_ID

IND-06

Gangoli

AFG-05

Najeeb

AFG-01

Nawroze

SA-09

Dal Styn

SA

A

 

Consider the following query:

 

SELECT Count (Player_Team.Pool_ID) AS CountOfPool_ID

FROM Player_Team

GROUP BY Player_Team.Pool_ID;

 

Answer the following questions:

 

  1. You need to identify the number of clusters from this data.
  2. Secondly, you have to identify whether the given clustering is one way or two way clustering. Your answer should support by valid reasons.

 

Question 2                                                                                                                                         [10 Marks]

Consider the following tables:

 

Player

 

Player_ID

Player_Name

Team

PK-01

Wasim

Pakistan

PK-02

Misbah

Pakistan

SA-03

AB Devillier

South Africa

 

Award

 

Award_ID

Match_ID

Player_ID

01

01

PK-01

01

02

PK-01

02

03

PK-02

01

04

SA-03

 

Consider the following query:

 

Select * from Player P, Award A where P.Team= ‘Pakistan’ and A.Award_ID = ‘01’ and P.Player_ID = A.Player_ID

 

Suppose this query is executed using Naive Nested-Loop join and (i.e. there is no index created on both Player and Award tables). Mention that which table should be the Outer table to get minimum I/O by manually calculating the cost in both cases i.e. when “Player” is outer table and when “Award” is outer table.

 

 

Note: You need to mention the calculations in your solutions where required.

secondly count query apko already global view tu dey rahi hay ab ager hum further data ko cluster karna chahain tu team id ki base pey kar saktey hain. so this might be our local view that is provided by bicluster. So someone may think on these lines to find the right answer....mujhey tu yehi samajh me aya.
