Answer:
check the explanation
Explanation:
Variables when it comes to programming are used to store data to be documented and manipulated in a computer program. They can also be used for labeling stored data with a descriptive name and any other needed details, so that the programs can be comprehended more understandably by the reader and ourselves.
to solve the question, we will write this set of codes;
numberOfIncompletes = 0;
for(k = 0; k < incompletes.length; k++)
{
if(incompletes[k] == studentID)
numberOfIncompletes++;
}
Answer:
Option (3) is the correct answer of this question.
Explanation:
- HCatalog makes available Hive metadata to users of other Hadoop applications, such as Pig, MapReduce and Hive. it offers interfaces for MapReduce and Pig so that users can read data from and write data to the Hive warehouse.
- This means users don't have to care about where or in what format their data is stored. So we know this way that Hcatalog makes sure our data is secure.
- Others option does not belong to Hcatalog so these options are incorrect .
Answer:
Make use of hash tables
Explanation:
The appropriate thing to use for this should be a hash table.
A Hash Table can be described as a data structure which stores data in an associative manner. In a hash table, data is stored in an array format, where each data value has its own unique index value. Access of data becomes very fast if we know the index of the desired data. So we can perform Hashing on ISBN Number since its unique and based on the Hash Function w ecan store the Information record.
There is no requirement for printing the file in order - HashTables dont store the data in order of insertions, so no problems with that
It becomes a data structure in which insertion and search operations are very fast irrespective of the size of the data. So Querying books details can be fast and searching will take less time.
It can also be pointed out that it wont be too expensive for Hardware implemtation as HashTables stores data based on Hash Functions and memory consumption is also optimal which reduces memory wastages.
Answer: Data and Insights
Explanation:
Data and Insights in an enterprise platform is very important as it helps users better understand their customers so that they may be able to offer them the best services.
Data allows the platform to capture the data of the customer and insights then curates and consumes the data for analysis. The result of this analysis will enable the company to better understand the customer so that they might be able to offer preferable products.
Answer:
A AND B= 1 or 0
1 1 1
0 1 0
1 0 0
0 0 0
So, as explained above if both are 1 we then only get 1, or else we get 0 always in case of AND which is a logical operator, whose output can be 0 or 1 only. This is being depicted above.
Explanation:
If both are 1 we get 1 or always else, we get the output =0.
