// This pseudocode is intended to describe

ddd [48]

Applying given information of a computational language in pseudocode, a code may be written to represent computing the price of an item on sale for 10% off.

<h3>What is a pseudocode?</h3>

A pseudocode can be considered as a depiction of the steps represented in an algorithm, usually in plain (natural) language.

//This pseudocode is intended to describe

//computing the price of an item on sale for 10% off

START

input origPrice

discount = origPrice * 0.10

finalPrice = origPrice - discount

output finalPrice

STOP

//This pseudocode is intended to compute the number

//of miles per gallon you get with your car.

START

input milesTraveled

input gallonsOfGasUsed

milesPerGallon = milesTraveled / gallonsOfGasUsed

//milesPerGallon is computed using division

output milesPerGallon

//miles is misspelled, and the P in milesPerGallon should be uppercase

STOP

//Program should end with stop

//This pseudocode is intended to describe

//computing the per day cost of your rent

//in a 30-day month

START

input rent

costPerDay = rent / 30

// Comment indicates 31-day month

output costPerDay

// output should be costPerDay

STOP

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.
