ETL vs ELT โ Explained Using Apple Juice analogy! ๐๐ง
We often hear about ETL and ELT in the data world โ but how do they actually apply in tools like Excel and Power BI?
Letโs break it down with a simple and relatable analogy ๐
โ ETL (Extract โ Transform โ Load)
๐ง First you make the juice, then you deliver it
โก๏ธ Apples โ Juice โ Truck
๐น In Power BI / Excel:
You clean and transform the data in Power Query
Then load the final data into your report or sheet
๐ก Thatโs ETL โ transformation happens before loading
โ ELT (Extract โ Load โ Transform)
๐ First you deliver the apples, and make juice later
โก๏ธ Apples โ Truck โ Juice
๐น In Power BI / Excel:
You load raw data into your model or sheet
Then transform it using DAX, formulas, or pivot tables
๐ก Thatโs ELT โ transformation happens after loading

Understand the power of Data Lakehouse Architecture for ๐๐ฅ๐๐ here...
๐จ๐ข๐น๐ฑ ๐๐ฎ๐
โข Complicated ETL processes for data integration.
โข Silos of data storage, separating structured and unstructured data.
โข High data storage and management costs in traditional warehouses.
โข Limited scalability and delayed access to real-time insights.
โ ๐ก๐ฒ๐ ๐ช๐ฎ๐
โข Streamlined data ingestion and processing with integrated SQL capabilities.
โข Unified storage layer accommodating both structured and unstructured data.
โข Cost-effective storage by combining benefits of data lakes and warehouses.
โข Real-time analytics and high-performance queries with SQL integration.
The shift?
Unified Analytics and Real-Time Insights > Siloed and Delayed Data Processing
Leveraging SQL to manage data in a data lakehouse architecture transforms how businesses handle data.
