ETL VS ELT (Data Pipeline)

ETL vs. ELT: The Data Pipeline Showdown!

Data pipelines are the workhorses of data engineering, moving data from source to analysis. This post explores ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform) approaches, along with data cleansing and transformation techniques.

ETL: Transform data before loading (like prepping ingredients before cooking).

ELT: Load data first, then transform within the target system (like throwing everything in the pot and then cleaning/chopping).

The right approach depends on factors like data size and …
