I recently enrolled in <strong>LUXDEV (Data Science and AI Analytics Cohort 9 2026)</strong>, and I'm excited to share my first updates!</p> <h2> 🎯 Why I Enrolled </h2> <p>I wanted to build a rock-solid foundation in Data Science and get certified instead of learning randomly without structure. My goal is to understand data analysis, structuring and how to deduce information from cleaned data, using this to make predictions and decisions.</p> <h2> 📚 What We've Covered So Far </h2> <p>Here is a quick summary of what I've tackled in the first couple of modules:<br> **1st Week: Software Installation and Initial Setups</p> <ul> <li> <strong>Git and GitHub:</strong> Installed and set up Git on my laptop and linked it with my existing GitHub account.</li> <li> <strong>DBeaver and Postgress:</strong> Installed Postgress and DBeaver. Used DBeaver to create DB on Postgress.</li> <li> <strong>Aiven:</strong> Created an account on Aiven Site. Created two services <code>MySQl</code> and <code>Postgress</code>. Linked both database with DBeaver for ease management.</li> </ul> <h2> 💡 Key Takeaway </h2> <ul> <li>DBeaver is a Open Source Database management tool</li> <li>Aiven is a online(cloud) platform for creating database and more and gives free usage for 1 DB at a time for learning purposes.</li> <li>Learned about this site <code>DEV</code> <em>Its the first time to hear about it</em> </li> </ul> <h2> 🚀 What's Next </h2> <p>This 2nd week we dive into the real deal now that we are set.</p> <p><em>I'd love to connect with others currently taking Data Science &amp; AI Analytics or learning Data Engineering.
