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.
Designers use both isometric and perspective sketches to
maintain an object’s visual proportions. Isometric sketches are 3D objects
drawn with lines that have no vanishing points while perspective sketches are 3D
objects drawn with one or more vanishing points.
Designers choose to use an
isometric sketch because it is more accurate than perspective drawings and
makes the design look more professional. Isometric sketches are much easier to
handle because the length of each measure is same as the plan. This is especially
for designers drawing pictures by hand. It is time saving and you do not need
to calculate the angle of every edge.
Answer:
The answer to this question can be described as follows:
Explanation:
Relational data model:
The use of data tables to organize sets of entities into relationships requires a relational data model. this model work on the assumption, which is a primary key or code, that is included in each table configuration. The symbol for "relational" data links and information is used by other tables.
Model Design:
This model is used for database management, it consists of structure and language consistency. It is design in 1969.
Importance of data model:
This provides a common standard for processing the potentially sound data in machines, that was usable on almost any one device.
Big Data:
It moves to locate new and innovative ways to handle large volumes of authentication tokens and to gather business insights when offering high efficiency and usability at an affordable cost at the same time.
No he did not that was a poor choice.

The correct answer is A. true.
It was written in 1948 by the bureau of Labor statistics .
