I Tried chDB for Analytics — Here’s What I Learned
Hello everyone! Welcome to another Interesting Tech Update on Analytics! Recently, I came across an interesting update about chDB in the TDLR Newsletter, which motivated me to explore it further. Until now, I’ve mostly worked with server‑based SQL engines such as PostgreSQL, MySQL, and SQL Server. I’ve also used serverless SQL engines on many challenge platforms like DataLemur, LeetCode, and HackerRank. These platforms typically use in‑process SQL engines, which don’t

Hospital Data Analysis Using Python
Healthcare organizations generate huge amounts of patient and provider data daily. In this blog, we use Python to analyze the HC Dataset from Kaggle, focusing on patient discharge trends, provider specialties, and ambulatory visit patterns. Key insights include variations in length of stay (LOS), discharge dispositions, and visit volumes, which help hospitals optimize staffing, improve operational efficiency, and improve patient care.

Part 2: Beyond the Spreadsheet: Decoding the Hidden Patterns of Cinema
I. The Goal: Testing the Hype In my last post, I documented how I built a custom dataset by pulling live data directly from Wikipedia. It was a process of turning messy web tables into a structured CSV file. Today, I’m putting that data to work to answer a question many of us have: Are record-breaking box office numbers a consistent new trend or are we just seeing a few lucky hits? By looking at the last 30 years of cinema, I wanted to see if the "Billion Dollar Club" is actu

Part1: Beyond the CSV: Engineering Custom Datasets with Python
Introduction: Challenging the Traditional Analytics Workflow Usually, the roadmap for building a data portfolio follows a very specific, linear path. The formula is familiar to almost everyone entering the field: Find a pre-cleaned dataset on a portal like Kaggle. Download the static CSV file. Clean any minor remaining errors using Excel, SQL or Power BI. Visualize the results in a standard dashboard. It’s a safe and effective process for learning the basics. However, as

Why Statistics are Just Nutrition Label: The Mystery of Anscombe’s Quartet
As I began my journey as a Data Analyst, I often found myself questioning a fundamental part of the job: If I have already done the math, why do I need the picture? I was meticulously calculating means, variances, and correlations for every dataset that crossed my desk. I felt that if the math was accurate, the story was told. Why spend hours perfecting a chart when the 'truth' was already sitting there in the totals? That skepticism vanished the moment I came across Anscomb

🌙 Beyond the Numbers: The Art of Listening to Your Body’s Data
Decoding the Silent Language: How Visuals Turn Bio-Data into Action Your body is constantly speaking to you, but it speaks in a language of numbers that most of us can’t instinctively understand. Every heartbeat and sleep cycle is a data point in the vast experiment of the "Quantified Self". As a Data Analyst, I believe our job is to act as translators. If we use the wrong visual "lens," the story of our health becomes noise. But with the right representation, we can finally

The Live Clinical Dashboard: Transforming Heart Disease Data into an Interactive Experience with Plotly
The "Why": From Reporting to Empowering As a data analyst, I’ve realized that insights are often "trapped" within the technical environments where they are created. In my previous analysis, I utilized Tableau to create a visual representation of the heart disease data. While Tableau is exceptional for discovery, I realized that for a clinical tool to be truly interactive and "live" in a custom web environment, a doctor or researcher needs a workspace that exists on their own

From COVID Survey Chaos to Clean Insights
The Python hackathon gave me hands-on experience analyzing the Flatten COVID-19 dataset in Jupyter Notebook—the digital lab book where data scientists prototype Python, R, and more. Before writing a single line of code, I learned the first rule of data analysis: deeply understand your dataset first. Dataset Reality Check: This wasn't hospital lab data. It contained self-reported COVID-19 symptom surveys from Ontario residents during early 2020, split across 3 evolving schemas
