Extract, Transform, Load (ETL) is the process of collecting data from an unlimited number of sources, organizing all the data together, and centralizing it into a single repository. The use cases of ETL are as follows:

• Transferring data from one application to another.
• Redundancy analysis
• Transferring data into a data warehouse for retrieval, sort or transform into another form for business intelligence.
• Turn raw data collected from transactions into clean information and actionable business intelligence.

• Collaboration and unifications of systems.
• Time saving.
• Reduction of rework.
• Removes junk data.
