One reason for this is:  the processing power needed for the centralized model would overload a single computer.

<u>Explanation:</u>

Companies would be engrossed in achieving and examining the datasets because they can supplement significant value to the desicion making method. Such processing may include complicated workloads. Furthermore the difficulty is not simply to save and maintain the massive data, but also to investigate and extract a essential utilities from it.

Processing of Bigdata can consists of various operations depending on usage like culling, classification, indexing, highlighting, searching etc. MapReduce is a programming model used to process large dataset workloads. Hadoop is designed to scale up from single servers to thousands of machines, each offering local computation and storage.

Assume the input data is structured as follows: first there is a non-negative integer specifying the number of employee timeshee
Vesna [10]

Answer:

int employees;   //set integer type variable

int a,b;     //set two integer type variable

int wage=0;   //initialize integer type variable

int hours=0;   //initialize integer type vcariable

total=0;    

cin >> employees;    //get input from the user

for (a=1; a<=employees; a++){     //set for loop

cin >> wage;     //get input from the user

for (b=1; b<=5; b++){    //set for loop

cin >> hours;    //get input from the user

total += hours * wage;    //perform multiplication

}

}

Explanation:

Here, we define four integer type variable "a", "b", "wage" "hour" and assign value in "wage" to 0 and "hours" to 0.

Then, we get input from the user in the variable "employees".

Then, we set the for loop and pass the condition inside it we get input from the user in the variable "wage".

Then, again we set the for loop and pass the condition inside it we get input from the user in the variable "hours".

Then, we perform addition and the multiplication.

Your company wants to conduct an exploratory study to gain new insights into some product changes you are considering. Which typ
Lina20 [59]

Answer: Primary Research (Focus Group).

Explanation:

Exploratory Research is an inquiry that seeks to understand the basic causal factors of a problem. This effort can serve as the basis of more intensive research later on.

There are basically two methodologies used, which are the; Primary and Secondary methods. While the Primary method's source of information is the concerned group, the Secondary Methods obtain their information from already existing information (Primary sources), such as Interviews, Journals, etc.

In the case of the company in the question, seeking to gain insight into the changes in a product, it would be best for them to consider what some selected costumers (focus group), think about the existing products and their views on subsequent changes. This method of getting information directly from the focus group employs the primary method.
