Answer:

Databases are not that simple. Now we not only have a Data warehouse, but we also have the Data Lake as well. We also have NoSQL and SQL form of support with these modern databases. The JSON format is rocking. You can hence through JSON store the text, image, audio, video, etc in one go. And like the first five can be a text, the next five can be an image then again a text than video, and so on. And it is super easy to access them as well. Also, you can edit them quite easily as well. It's not that hard like the Lisp used to be in the past. And supermarket has a mix blend of the database. And modern databases like Data Lake can be very useful, undoubtedly.

You can store security type of requirements, like CCTV footage, each shop details like shop ID, Product list, shop type, electricity bill, hours of opening, floor, facilities, no. of employees, etc., and like this, we can have the details for the entire supermarket, and each shop there definitely. And we can perform various actions on behalf of each shop and market as well. The database can hence be very useful definitely

What is a limitation of 5G mmWave, despite its high speed?

Allushta [10]

The limitation of 5G mmWave, despite its high speed, is the fact that they have a short range.

5G simply means the fifth generation of wireless technology that has great speed and provides connectivity to cellphones.

mmWave is the higher frequency radio band that is very fast. It should be noted that the 5G mmWave is super fast and is being used by large organizations to improve their work.

The main limitation of 5G mmWave is that for one to use it, one has to be close to the 5G tower. This is why it's hard for people living in rural areas to benefit from it unless it's situated close to them.

It should be noted that despite the fact 5G offers greater bandwidth, which is vital in relieving network congestion, there are still more improvements to be made in order for everyone to benefit.

In conclusion, the limitation of 5G mmWave, is that they have a short range.

public static void main(String args[])

{

int decimalExample = Integer.parseInt("20");

int signedPositiveExample = Integer.parseInt("+20");

int signedNegativeExample = Integer.parseInt("-20");

int radixExample = Integer.parseInt("20",16);

int stringExample = Integer.parseInt("geeks",29);

// Uncomment the following code to check

// NumberFormatException

// String invalidArguments = "";

// int emptyString = Integer.parseInt(invalidArguments);

// int outOfRangeOfInteger = Integer.parseInt("geeksforgeeks",29);

Suppose that we pick the following three tuples from a legal instance of a relation S (S has 100 tuples in total). Relation S ha

AysviL [449]

Answer:

The correct answer is BC → A, A does not hold over S. we noticed the tuples (1 ,2 ,3 ) and (4 ,2 ,3) which can hold over S)

Explanation:

Solution

No, since in this case the instance of S is provided. so such particular dependencies are unable to breach through such instance, but unable to tell which the dependencies hold towards S.

A functional dependency holds towards only when a relation forms a statement regarding the complete allowed instances of relation.
