The changes involve adding a new table to represent the relationship between customers and sales reps, modifying the existing tables to accommodate the new relationship, and ensuring that the sales rep associated with a customer is included when the customer places an order.
To support the requirement that a customer can be represented by several sales reps, the original KimTay Pet Supplies database design needs the following changes:
Add a new table called "Customer_Rep" to represent the relationship between customers and sales reps.
In the "Customer_Rep" table, include the primary key of the customer and the primary key of the sales rep.
Remove the "Sales_Rep_ID" foreign key from the "Customer" table.
Modify the "Order" table to include a foreign key referencing the "Customer_Rep" table.
When a customer places an order, the sales rep who gets the commission on the invoice must be in the collection of sales reps associated with that customer.

the perception of higher-pitched sounds is called ________ coding.
The perception of higher-pitched sounds is called place coding. Place coding is also known as tonotopic organization, which refers to the way sound frequency is processed by the cochlea.
Place coding, which is the perception of higher-pitched sounds, is based on the location of the hair cells along the basilar membrane within the cochlea. The cochlea is a tiny snail-shaped part of the inner ear that is responsible for processing sound vibrations and sending them to the brain for interpretation.
The basilar membrane of the cochlea is the structure that separates the upper and lower chambers of the cochlea. The vibration of the basilar membrane is proportional to the frequency of the sound wave that entered the ear canal.
In general, higher-pitched sounds cause the basilar membrane to vibrate more at the base of the cochlea, whereas lower-pitched sounds cause the basilar membrane to vibrate more at the apex of the cochlea, which is the farthest end from the oval window.

write a brief note on computer monitor
Answer:
A computer monitor is an electronic device that displays digital images generated by a computer's graphics card. It is one of the essential components of a computer system, allowing users to interact with the computer and view its output. Monitors come in various sizes, resolutions, and display technologies such as LCD, LED, OLED, and CRT.
Modern computer monitors usually have a flat-panel display, which is thinner and consumes less power than the older CRT (cathode ray tube) monitors. Monitors can be connected to the computer through various interfaces, such as VGA, DVI, HDMI, and DisplayPort, and some models have built-in speakers or USB ports for added functionality.
The resolution of a monitor determines the number of pixels it can display horizontally and vertically, with higher resolutions providing more screen real estate and sharper images. Refresh rate is another important factor, with higher refresh rates allowing for smoother motion and reducing eye strain.
In summary, a computer monitor is an essential component of a computer system that displays visual output to the user, and choosing the right monitor for your needs depends on factors such as size, resolution, display technology, and connectivity options.

It is also sufficient for storing the data and instructions that the computer is currently using and enables programs to run efficiently.
write an application that creates and returns a one dimensional array
To create and return a one-dimensional array in Java, you can use the following code snippet:```public int[] createArray(int size) {int[] arr = new int[size];for (int i = 0; i < size; i++) {arr[i] = i + 1;}return arr;}```This code defines a method named `createArray()` that takes an integer value as its parameter `size`.
The method creates an integer array of size `size` and initializes each element of the array with a value equal to its index plus one. Finally, the method returns the newly created array. Here, we can see that the return type of the method is an integer array.
You can test this method by calling it from the main method of your Java application, like so:```public static void main(String[] args) {int[] myArray = createArray(5);for (int i = 0; i < myArray.length; i {System.out.println(myArray[i]);}}```This code creates an integer array of size 5 and assigns it to the `myArray` variable. Then, it prints out each element of the array to the console. The output of this program would be:```

Suppose you have one machine and a set of n jobs a1, a2,.... ,an to process on that machine. Each job aj has processing time tj, a profit pj , and a deadline dj. The machine can process only one job at a time, and a job must run uninterruptedly for tj consecutive time units once it starts execution. If a given job aj is completed by its deadline dj , you receive a prot of pj ; otherwise, if the job aj is completed after its deadline, you receive a profit of 0. Give an algorithm to nd the schedule that obtains the maximum amount of prot, assuming that all processing times are integers between 1 and n. (Hint: You will need to show that scheduling jobs in increasing order of their deadline is the optimal scheduling approach. Also, the running time of your dynamic programming algorithm should be in terms of n and Dmax = Max j and n = 1 {dj} ).
Algorithm for Maximum Profit Job Scheduling the jobs in increasing order of their deadlines, and for each job, consider two possibilities - either include the job in the schedule or exclude it. By considering these possibilities dynamically, we can determine the optimal schedule that maximizes profit.
To implement the algorithm, first sort the jobs based on their deadlines in non-decreasing order. This sorting step ensures that jobs with earlier deadlines are scheduled first. Then, initialize a dynamic programming table with n+1 rows and Dmax+1 columns, where n is the total number of jobs and Dmax is the maximum deadline among all jobs. The dynamic programming table will be filled in a bottom-up manner. For each job, starting from the earliest deadline, calculate the maximum profit that can be achieved by either including or excluding the job. By considering the maximum of these two possibilities, update the dynamic programming table accordingly. Finally, the bottom-right cell of the dynamic programming table will contain the maximum profit achievable. By backtracking through the table, we can reconstruct the optimal schedule. The time complexity of this dynamic programming algorithm is O(n^2), where n represents the number of jobs. Sorting the jobs takes O(n log n) time, and filling the dynamic programming table takes O(n^2) time. Therefore, the overall time complexity is dominated by the dynamic programming step. By sorting the jobs based on their deadlines, we ensure that jobs with earlier deadlines are scheduled first. This approach guarantees that if a job cannot be completed within its deadline, it will not affect the scheduling of subsequent jobs. Thus, scheduling jobs in increasing order of their deadline is the optimal scheduling approach, ensuring the maximum profit is obtained.

communication privacy management explains how people determine what rules and boundaries govern what they will and will not disclose.
Communication privacy management (CPM) is a theoretical framework that elucidates how individuals make decisions regarding the disclosure or withholding of personal information.
It describes the process through which people establish rules and boundaries concerning their private information, taking into account various factors such as relationships, cultural norms, and personal values.
CPM suggests that individuals view their private information as a resource that they own and have control over. They create "privacy boundaries" to protect this information, and these boundaries can differ across individuals and contexts.
The decision-making process involves assessing the risks and rewards associated with sharing or withholding information. People consider factors like trust, relevance, reciprocation, and the potential impact on relationships when determining what to disclose.
The CPM theory recognizes that privacy is not a static concept, but a dynamic process influenced by changing circumstances and technological advancements.
With the proliferation of digital communication platforms, individuals must also consider the implications of online sharing, privacy settings, and data security.
Overall, CPM provides a framework for understanding how individuals navigate the complex terrain of communication privacy. By considering their relationships, cultural norms, and personal values, individuals establish rules and boundaries that govern what they are willing to disclose, enabling them to protect their privacy while maintaining meaningful connections with others.
