-
Image
 Here's a Python program that says to write a Symmetric array transformation. A top interview question. Symmetric Array Transformation Problem: Write a Python function that transforms a given array into a symmetric array by mirroring it around its center. For example: Input: [1, 2, 3] Output: [1, 2, 3, 2, 1] Hints: Use slicing for the reverse part. Concatenate the original array with its mirrored part. Example def symmetric_array(arr):     """     Transforms the input array into a symmetric array by mirroring it around its center.     Parameters:     arr (list): The input array.     Returns:     list: The symmetric array.     """     # Mirror the array by concatenating the original with its reverse (excluding the last element to avoid duplication)     return arr + arr[-2::-1] # Example usage input_array = [1, 2, 3] symmetric_result = symmetric_array(input_array) print("Input Array:", input_arr...

What is so Trendy in Data Visualization and Reporting

-
Data Visualization: Data visualization is the process that defines any effort to assist people to understand the importance of data by placing it in a visual context. 

Patterns, trends, and correlations that might be missed in text-based data can be represented and identified with data visualization software.

It is a graphical representation of numerical data. This is one of the Hot skills in the market, you will get the highest salary.

Types of data visualization

Visual Reporting

  1. Visual reporting uses charts and graphics to represent business performance, usually defined by metrics and time-series information.
  2. The best dashboards and scorecards enable the users to drill down one or more levels to view more detailed information about a metric
  3. A dashboard is a visual exception report that signifies the ambiguities in performances using visualization techniques

Visual Analysis

  1. Visual-analysis allows users to visually explore the data to observe the data and discover new insights 
  2. Visual-analysis offers a higher degree of data interactivity 
  3. Users can visually filter, compare, and correlate the data at the speed of thought incorporating forecasting, modeling, and statistical analysis 
  4. Data Visualization Representations

Business Intelligence Dashboard

  1. A business intelligence dashboard is a data visualization tool that represents the current status of metrics and key performance indicators for an enterprise 
  2. Dashboards combine and arrange numbers, metrics and sometimes performance scorecards on a single screen. They can be customized for a specific role and display metrics targeted for a single point of view or department 
  3. Microsoft and Oracle are some of the vendors for business intelligence dashboards. 
  4. BI dashboards can also be created through other business applications, such as Excel. They are sometimes referred to as enterprise dashboards. 

Performance Scorecard

  1. It is a graphical representation of the progress over time of some entity, such as an enterprise, an employee or a business unit that functions towards some specified goal 
  2. The important factors of performance scorecards are targets and key performance indicators (KPIs). 
  3. KPIs are the metrics that are used to evaluate factors that are essential for the success of an organization 
  4. The main difference between a business intelligence dashboard and a performance scorecard is that a business intelligence dashboard, like the dashboard of a car, indicates the status at a particular point in time. A performance scorecard displays the progress over time towards specific goals

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
