Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.

Overclocking is forcing the Central Processing Unit to run at a faster speed than the recommended manufacturer setting. While the CPU may function at a higher speed, it is not recommended because it could damage your CPU.
Which would suck, since replacing that small chip tends to be costly.
Each of the 20 people has 19 other people to communicate to. If you add that all up you get 20*19 paths, but then each path is counted twice (back and forth), so we divide this by 2. 20*19/2 = 190.
The general forumula is n(n-1)/2
A program that repeatedly prompts a user for integer numbers :
biggest = none
smallest = none
while True:
input = raw_input(“Enter a number:”)
if(input == “done” break
try:
number = float(inp)
except ValueError:
print “Please enter only numbers”
else
if smallest is None:
smallest = number;
biggest = number;
elif number < smallest:
smallest = number
elif num > largest:
largest = number
Print “Greatest is “, biggest
Print “Smallest is”, smallest
In this program an input is obtained, if it is equal to the word “done”, then the program stops b printing greatest and smallest number in the given input.
If invalid inputs are given then user is prompted to enter valid number. Otherwise the value of smallest and greatest are calculated according to the input using if-else construct.
