Here are SQL-focused interview questions with only the relevant SQL code: 1. Find the second highest salary from an Employee table. SELECT MAX(Salary) AS SecondHighestSalary FROM Employees WHERE Salary < (SELECT MAX(Salary) FROM Employees); Using ROW_NUMBER(): WITH RankedSalaries AS (   SELECT Salary, ROW_NUMBER() OVER (ORDER BY Salary DESC) AS Rank   FROM Employees ) SELECT Salary AS SecondHighestSalary FROM RankedSalaries WHERE Rank = 2; --- 2. Write a query to calculate a running total of sales. SELECT   OrderID,   OrderDate,   Amount,   SUM(Amount) OVER (ORDER BY OrderDate) AS RunningTotal FROM Orders; --- 3. Retrieve customers who placed no orders using a LEFT JOIN. SELECT c.CustomerID, c.CustomerName FROM Customers c LEFT JOIN Orders o ON c.CustomerID = o.CustomerID WHERE o.OrderID IS NULL; --- 4. Write a query to find the top 3 highest salaries. SELECT DISTINCT Salary FROM Employees ORDER BY Salary DESC LIMIT 3; Using DENSE_RANK(): WIT...

The space technology insurance sector is evolving rapidly, driven by increased commercial space activities, technological advancements, and emerging risks. Key trends shaping this industry include: 1. Expansion of Coverage Areas Satellite Insurance: This remains crucial for both governmental and commercial entities, covering various stages from pre-launch to in-orbit operations. Policies typically address launch failures, in-orbit malfunctions, and third-party liabilities.  Launch and In-Orbit Coverage: Insurers offer protection against potential losses during the critical phases of satellite deployment and operation, ensuring financial safeguards against unforeseen events. Personal Accident Insurance for Astronauts: With the rise of human spaceflight and space tourism, there's a growing demand for policies that cover accidents, injuries, or fatalities during missions. 2. Rising Demand Due to Commercial Space Activities Proliferation of Small Satellites: The surge in sm...

Concept Overview: SpaceTech Insurance Dataset Creation and Agile Workflow Planning Business Context SpaceTech insurance is an emerging field addressing risks associated with space exploration, satellite launches, and orbital operations. Insurance companies require robust datasets and workflows to assess risks, underwrite policies, manage claims, and ensure regulatory compliance. By creating an agile dataset and workflow planning approach, insurers can streamline operations, improve decision-making, and adapt to the dynamic nature of the SpaceTech industry. Business Research Market Demand: Increased reliance on satellites for communication, GPS, and Earth observation. Growing investments in private space exploration companies li...

 Kaggle Notebook Gemma 2B Fine Tuned Lightweight model Step 1: Configure GPU for Memory Growth python gpus = tf.config.list_physical_devices( 'GPU' ) if gpus: try : for gpu in gpus: tf.config.experimental.set_memory_growth(gpu, True ) print ( "GPU memory growth enabled." ) except RuntimeError as e: print (e) else : print ( "No GPU found. Using CPU." ) Purpose : Ensures the GPU is set to dynamically allocate memory instead of pre-allocating all available GPU memory. This approach prevents memory wastage and allows multiple processes to use the GPU without running into memory allocation errors. Technical Details : tf.config.list_physical_devices('GPU') : Lists available GPUs. tf.config.experimental.set_memory_growth(gpu, True) : Allows TensorFlow to allocate GPU memory on demand. Fallback : If no GPU is found, the code defaults to CPU computation. Step 2: Enable Mixed Precision for Memory Optimizatio...
