Explanation:
Big data refers to huge collections of data that are difficult to process, analyze, and manage using conventional data tools. It is a core component of the 3rd platform, which also includes cloud computing, mobile devices, and social networking. The five Vs of big data are high volume, high velocity, diversified variety, unknown veracity, and low-density value. Although SQL and relational databases can be used for big datasets, a collection of alternative tools referred to as NoSQL has become popular. These tools work well when databases scale out (horizontally) and when databases are broken into subsets called shards. Modern database tools also handle dynamic scaling as devices are added when additional capacity is required. NoSQL tools are sometimes said to create schema-less databases, but they usually have some type of structure, though it may be more flexible than the relational model. A key-value data model provides each data element with a key. A column-oriented data model makes it easy to access data stored in similar fields, rather than in individual records. Two very popular NoSQL tools include Hadoop, which is a big data file system, and MapReduce which sends processing logic to the data, rather than bringing the data to the computer that performs the processing.
Answer:
Following are the statement in C++ Language is given below
total=0; // variable declaration
cin >> amount; // Read the input
while(amount >=0) //iterating the loop
{
if(amount>0) // checking condition
total=total+amount; // perform operation
}
Explanation:
Following is the description of the statement
- Declared a variable "total" and initialized with them 0 to them.
- Read the input in the "amount" variable by using cin.
- iterating the loop when the amount is greater then 0.
- Checking the condition if(amount>0) then adding the total variable and amount and storing them into the total variable.
If (sales >= 10000)
commission = 0.2;
Answer:
We need to find first the location, and then we need to note down the barometric pressure of each hour in tenth place without decimal like 1013.3 mb is equal to 133 and so on. And the rate can be steadily increasing, steady, steadily decreasing, steadily increasing and then falling, steadily falling and then increasing, and so on. To find the rate of increase in barometric pressure, we need to find the rate of change of barometric pressure, and this will be clear if we prepare the chart of the barometric pressure of each hour during the past three hours. The graph plotted will give us a clear indication through its slope.
