I\'ve tried reading the Wikipedia article for \"extract, transform, load\", but that just leaves me more confused...

Can someone explain what ETL is, and how it is

    ETL is commonly used for data warehousing. It's not a specific implementation to load a data warehouse, it's just a very high-level algorithm that should be used to populate a data warehouse.

    • Extract pulls data from some source.
    • Transform takes the data and manipulates it so that it can be used for..
    • Loading into your system.
