What is the purpose of a staging area?
Answer / Rachna Chaudhary
{"staging area": "A staging area is an intermediate storage location in ETL processes. Its primary purpose is to temporarily store and organize data before it is transformed, validated, and loaded into the final destination (like a data warehouse or data mart). The staging area helps to isolate the ETL process from the source systems, ensuring data consistency and improving performance."
