Star Schema vs Snowflake Schema
A warehouse model can be technically correct and still perform badly if the schema choice is wrong.
Star schema and snowflake schema are two common ways to organize dimensional models. There are others like Galaxy schema.

โ Snowflake schema may be useful when dimension hierarchy needs strict normalization
๐Why it matters for data engineers: Most analytics teams care about query speed, readability, and simplicity. That is why star schema is often the better default for warehouses powering

dashboards and reporting layers. Snowflake can work, but it often adds complexity that business users and analysts do not need.
๐กIf you have worked with both, which one gave you fewer headaches in production: star or snowflake? Share your experience.

Dimensional Modelling
A warehouse only becomes useful when the data model is built for analysis, not just storage.
Dimensional modeling is the backbone of analytical data design. It structures data around facts and dimensions, making it easier to query, aggregate, and

It also reduces confusion between transactional data and analytical data.
๐When you design a model, start with one question: What is the business event I am measuring, and what context do analysts need around it?

Nobody talks about the part of learning Data Engineering. You understand the tools but you don't feel like an engineer yet. It's a practice problem. Praxicraft was built to put Data Engineers inside real problems.

โจ Are you feeling stuck in your data engineering journey? Core Data Engineers (CDE) is here for you ๐ค
Many aspiring data engineers don't struggle because they lack potential. They struggle because they lack the right guidance, structure, and support.
That's why CDE exists.

A proud moment for the Data Engineering Community ๐
Our founder Najeeb Sulaiman recently joined Astronomerโs podcast to share lessons from building with Apache Airflow at scale and experiences from the field.
This is the kind of impact we love to see learning, building,
After several years of building with Apache Airflow and teaching it to hundreds of engineers, I was recently invited by Astronomer โ the company behind Apache Airflow, to share my experience with the global Airflow community on The Data Flowcast Podcast.
