What is staging in ETL? A staging area, or landing zone, isan intermediate storage area used for data processing during the extract, transform and load(ETL) process. The data staging area sits between the data source(s) and the data target(s), which are often data warehouses, data marts...
The data is most often moved through a process known asextract, transform, load (ETL)or sometimes a process known asextract, load, transform (ELT). These processes are executed in different ways, but they both use automation to move data into a warehouse and prepare it for use in ...
