SELECT statement:
It is used to retrieve information from the table or
SELECT * FROM table_Name;
Expert Solution & Answer

Explanation of Solution
Difference between “WHERE” and “HAVING” clause:
“WHERE” clause | “HAVING” clause |
“WHERE” clause is used limit the number of rows. | “HAVING” clause is used limit groups. |
“WHERE” clause cannot be used with aggregate functions. | “HAVING” clause in used to overcome “WHERE” clause because, “HAVING” clause uses aggregate functions. |
Syntax: SELECT column_Name(s) FROM table_Name WHERE condition; |
Syntax: SELECT column_Name(s) FROM table_Name GROUP BY column_Name HAVING condition; |

The Horse table has the following columns:
ID - integer, auto increment, primary key
RegisteredName - variable-length string
Breed - variable-length string
Height - decimal number
BirthDate - date
Delete the following rows:
Horse with ID 5
All horses with breed Holsteiner or Paint
All horses born before March 13, 2013
To confirm that the deletes are correct, add the SELECT * FROM HORSE; statement.
Why is Linux popular? What would make someone choose a Linux OS over others? What makes a server? How is a server different from a workstation? What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
Objective you will:
1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five)
2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector.
3. Compare the performance of TreeSort with C++'s std::sort on large datasets.
Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST):
1. Insert all elements into a BST (logically sorting them).
2. Traverse the BST in-order to extract elements in sorted order.
3. Store the sorted elements in a vector.
Time Complexity
Operation Average Case Worst Case (Unbalanced Tree)Insertion 0(1log n) 0 (n)Traversal (Pre-order) 0(n) 0 (n)Overall Complexity 0(n log n) 0(n^2) (degenerated tree)
