Big Data:
- Big data is enormously large sets that may be analyzed computationally to expose trends, association and patterns particularly relating to human interactions and behavior.
- Big data challenges include data storage, search, transfer, data analysis, querying, sharing, information privacy, data source, querying, visualization and updating.
- Due to the technology evolution happened in the last 50 years, big data came into fruition.
- There was a transformation in the data landscape due to the revolutionary technological advances in software, hardware, storage, networking, and computing models which made new opportunities for data collection...

Online Analytical Processing:
- OLAP (Online Analytical Processing) is a tool that provides multidimensional views of their data.
- It uses the query and tool to provide the multidimensional view and uses the simple windows techniques to analyze the data
Explanation of Solution
Data Mining:
- Data mining is a tool for analyzing the data.
- It is used for analyzing the data from different views and shortened into the useful information.
- In other words, it can be said data mining is a process that helps in finding patterns or correlations between multiple fields in severe relational databases.
Types of information obtained from data mining:
The different types of information provided by data mining are as follows.
- Associations – It is defined as the occurrences which are connected to a single event.
- Sequences – It is defined as the occurrences when events are connected over time.
- Classifications – It is defined as the recognition of patterns and relationships which define the group to which an item belongs...

Text mining and web mining differing from conventional mining:
- Web mining is defined as the analysis of patterns and relationships from the World Wide Web.
- Text mining is defined as the tool for analyzing data which may work by obtaining impor...
Explanation of Solution
Accessing information:
- One of the ways by which the users can access information from a company’s internal databases through the web is by using web browser software on their PC.
- The client can connect to the
database and can request data. The requests are usually done by using HTML commands to communicate with the web server...

- Change the following code so that there is always at least one way to get from the left corner to the top right, but the labyrinth is still randomized. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. Take care that the player and the dragon cannot start off on walls. Also the dragon starts off from a randomly chosen position public class Labyrinth { private final int size; private final Cell[][] grid; public Labyrinth(int size) { this.size = size; this.grid = new Cell[size][size]; generateLabyrinth(); } private void generateLabyrinth() { Random rand = new Random(); for (int i = 0; i < size; i++) { for (int j = 0; j < size; j++) { // Randomly create walls and paths grid[i][j] = new Cell(rand.nextBoolean()); } } // Ensure start and end are…arrow_forwardChange the following code so that it checks the following 3 conditions: 1. there is no space between each cells (imgs) 2. even if it is resized, the components wouldn't disappear 3.

He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forward
