What is the difference between ETL and ELT?

ETL (Extract, Transform, Load) transforms data before loading it to the destination — common in traditional on-premise data warehouses where compute was expensive. ELT (Extract, Load, Transform) loads raw data first, then transforms it inside the cloud warehouse using its powerful compute — the modern approach favored with cloud data warehouses like Snowflake or BigQuery where storage is cheap and compute scales on demand.

What is Data Management?

Data management infrastructure powers analytics — data warehouses (Snowflake, BigQuery, Redshift) store and query large datasets, ETL/ELT tools (dbt, Fivetran, Airbyte) move and transform data between systems, and master data management ensures consistent, accurate reference data across the organization.

Who needs this?

Building a cloud data warehouse to centralize analytics data
Setting up automated data pipelines from source systems to warehouse
Ensuring consistent master data (products, customers) across systems
