Complete the following: For each of the following actions, use each language to complete a programming solution. Please copy the numbered action into your Microsoft Word document. Please post your code for Python to cover item 1 below. For items 2–3 below, provide a screenshot of the execution, in Java and R, showing the code and the result set. Be sure to submit the actual .py file for Python in this module. Make sure to also respond to items 4 and 5. Start a next action on a new page. For items 1–3, use the file. 1. Write a Python program that reads the CSV file into a Panda dataframe. Using that dataframe, print the row, source IP, and destination IP as a table. 2. Write a Java program that reads the CSV file into an ArrayList. Convert the ArrayList to a string array and print the row, source IP, and destination IP on the same line using a loop. 3. Write an R program that reads the CVS file using the read.csv data type. Print the row, source IP and destination IP of each line. 4. Compare and contrast the data collection used for each language. 5. Discuss the data science process.

4. Compare and contrast the data collection used for each language.

When it comes to data collection, Python, Java, and R offer different approaches and libraries to handle this task.

Python, being a popular language in data science and machine learning, provides several libraries for data collection. One of the most commonly used libraries is Pandas, which allows easy manipulation and analysis of structured data. In the provided action, the Python program uses the Pandas library to read the CSV file into a Pandas DataFrame, which is a two-dimensional data structure similar to a table. This DataFrame can then be used to access and manipulate the data, including printing specific columns like the row, source IP, and destination IP.

Java, on the other hand, does not have built-in libraries specifically designed for data analysis and manipulation like Pandas in Python. However, Java offers various libraries and frameworks that can be used for data collection and processing. In the given action, a Java program is used to read the CSV file into an ArrayList, which is a dynamic-sized array that can store elements of any type. From there, the ArrayList is converted to a string array using a loop, and the desired row, source IP, and destination IP are printed on the same line. This approach in Java requires more manual coding compared to Python’s Pandas library.

R, a language widely used for statistical analysis and data visualization, has its own set of libraries and functions for data collection. In the provided action, the R program utilizes the read.csv function to read the CSV file into a data frame. The data frame is a data structure in R that is similar to a table and allows easy access and manipulation of data. Similar to Python’s approach, the R program prints the desired row, source IP, and destination IP using the data frame.

5. Discuss the data science process.

The data science process refers to a set of steps or phases that data scientists follow to extract insights and knowledge from data. While the exact steps may vary depending on the context and specific problem, the general data science process typically includes the following stages:

1. Problem definition: Clearly define the problem or question that needs to be answered. This involves understanding the business context and the goals of the analysis.

2. Data collection: Gather relevant data from various sources. This may involve web scraping, database queries, or accessing data from APIs. The choice of data collection method depends on the availability and nature of the required data.

3. Data preprocessing: Clean and preprocess the collected data to ensure its quality and usability. This step involves tasks like removing duplicates, handling missing values, transforming variables, and normalizing data.

4. Exploratory data analysis: Perform an initial exploration of the data to gain insights and identify patterns or relationships. This may involve summary statistics, visualizations, and statistical tests.

5. Model building: Develop a data model or algorithm that can be trained on the data to make predictions or provide insights. This step may involve choosing an appropriate machine learning algorithm, feature engineering, and model validation.

6. Model evaluation: Assess the performance of the developed model using appropriate evaluation metrics. This helps determine how well the model captures the underlying patterns and whether it generalizes well to new data.

7. Model deployment: Once the model is deemed satisfactory, it can be deployed in a production environment to make predictions or provide recommendations. This may involve integrating the model into existing systems or building an application around it.

8. Model monitoring and maintenance: Continuously monitor the performance of the deployed model and update it if necessary. As new data becomes available or the problem domain changes, the model may need to be retrained or adjusted.

Overall, the data science process is an iterative and cyclical process, where each stage informs and influences the subsequent stages. It requires domain knowledge, statistical expertise, programming skills, and the ability to effectively communicate and visualize results.
