r) \wedge \neg q\]

Let me re-write the proposition:

p↔q⊕(¬p↔¬r)∧¬q.

Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:

p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1

BITS wants to store information about the supervisors, including their supervisor number and the relationship to consultants. Su
Olin [163]

Answer:

Convert the table into normalize form

Explanation:

Un normalized relation of the given schedule is as

Consultant ( ConsultNum, Last Name, First Name, Street, City, ZipCode

HoursRate (SupervisorNum, Supervisor Num)

(Tasks, Description, Catagory, Price, SupervisorNum))

According to these functional dependencies :

SupervisorNum is dependencies of the SupervisiorNum

ConsltNum is dependencies of the Last Name, First Name, Street, City, ZipCode, Hours, Rate

Tasks are dependencies of Description, Category, Price

The consultant table is not in a normalized form as it contains repeating groups. Make composite keys such as Supervisor Num, Tasks and ConsltNum and convert the table in NF by removing repeating groups

Such as table in NF

Consultant

(Consult Num, Last Name, First Name, Street, City, Zip Code, Hours, Rate

Supervisor Num, Supervisor Name, Tasks, Description, Category, Price)

Explanation:

Proportion is an important aspect in design theory in terms of size. It refers to the relationship between object of the design in terms of size. The relation between size of different object in design theory can describe as, if the size of one object increases or decreases, it may leads to change in size of other object.
