I loved the hands‑on vibe of the 高度データウェアハウス専門士課程. It helped me finally nail down the difference between star and snowflake schemas, which was a personal learning goal. The practical labs using Google BigQuery were spot‑on – I built a dashboard for my charity that now pulls data in real time. The PDFs were clear and the video demos were short but thorough. I’m happy with the course and would recommend it to anyone looking to boost their data‑warehousing chops.
