Which BI tools are in demand in 2025 Planning to learn dbt → Power BI — need advice on the best niche and next steps?
I'm aiming to build a career in Business Intelligence. Given how competitive the job market is right now, I’ve decided to learn dbt and Power BI to strengthen my profile and understand the modern data stack better. I come from a non-technical background with a gap after graduation, but I’ve started learning SQL and want to focus fully on the BI side of things—dashboards, reporting, insights, etc. I'm curious to know: 1. How many BI tools are actively used in the current market? 2. Which BI tools are most valuable to learn in 2025? 3. What niche/role within BI makes sense for someone starting out like me and for professional career in future ? Would love any advice from professionals already working in BI—your suggestions will help me shape a clear roadmap. Thank you!
What is the difference between data science and machine learning?
I've been looking into data science careers, and I know that it is closely related with machine learning and big data. I'm confused as to what the difference between data science and machine learning is, and also how big data plays in a part in both fields. What exactly is data science and machine learning, and how are they related to each other (and how does big data tie into them)? Any help would be greatly appreciated. #data-analysis #data-science #computer-science #computer-software #big-data #machine-learning #data-visualization #data #data-mining
What are the best data science courses/nanodegrees I can take online?
I'm currently a third year computer science major, and I've recently discovered a passion for data science and machine learning. I've been trying to learn more about it, and I've found many online resources (Udacity's data analyst, machine learning nano degrees, Stanford's Intro to Machine Learning course taught by Andrew Ng, and various courses offered on Udemy). With all of these great resources, which one would be best for someone who is comfortable programming and wants to get more practical experience? Any advice would be very helpful (and even more so if you are a current data scientist!) and would be greatly appreciated! #machine-learning #data-analysis #data #big-data #computer-science #computer-software #data-science #data-mining #data-visualization
