148 ) ETL & ELT = when to suggest

 

    • Suggest ETL if the client is looking for:

      • Protecting weak databases: Keeping heavy data cleanup away from older or slow source systems so they don't crash or slow down.

      • Strict security upfront: Hiding or locking down sensitive information (like personal IDs or credit card numbers) before sending it anywhere else.

      • Saving storage space: Filtering out garbage data at the starting line so you don't pay to store junk.

    • Suggest ELT if the client is looking for:

      • Maximum speed with cloud power: Dumping raw data quickly into modern cloud tools (like Snowflake) and letting their massive computers handle the cleanup later.

      • Keeping a raw history book: Storing an exact, untouched copy of the original data just in case someone needs to look at it later for audits or machine learning.

      • Simpler, faster pipelines: Moving data over immediately without getting bogged down by complicated cleanup steps along the way.
