About Pragya Petika
प्रज्ञा पेटिका — Pragya means wisdom, and Petika is a box or casket. Together: a box of wisdom you open to find what’s worth knowing.
What it is
A technology knowledge hub in three sections. Data explains the platforms (Databricks, Microsoft Fabric, Snowflake) and data engineering and architecture concepts with interactive diagrams, and decodes every Databricks release. BI follows Power BI and Microsoft Fabric. AI indexes AI tools and GenAI. Everything links to the vendor’s own documentation, so you can check the facts in one click.
How it’s made
Facts come from official release notes and documentation. Summaries, concept explainers, diagrams and infographics are original. Practitioner topics are paraphrased from community newsletters, never copied. Pragya Petika is not affiliated with or endorsed by any vendor.
