A Complete, Modern Guide to Building a Data Warehouse and Data Lake (Warehouse + Lakehouse Architecture)
Deep Technical Series
Modern analytics platforms are no longer simple databases feeding dashboards. Today’s data teams must combine principles of dimensional modeling, cloud warehouses, lake storage, open table formats, scalable pipelines, governance, and performance engineering. The best systems blend classical data warehousing with modern lakehouse and cloud-native capabilities.
This long-form series teaches you how to build that system from scratch.
Readers will go from designing their first dimensional model all the way to implementing a real warehouse, a high-scale data lake, a lakehouse with Delta or Iceberg tables, automated pipelines, CDC ingestion, governance, and end-to-end performance tuning.
The entire series is built on modern tools like:
- Snowflake
- Microsoft Fabric
- Azure Synapse
- Databricks
- AWS Glue + S3 + Redshift
- Google BigQuery
- dbt Core / dbt Cloud
- Apache Spark
- Delta Lake / Iceberg
- Fivetran
- Airbyte
Every step works across all major platforms.
Every part includes clickable inline references and a final reference list.
