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.
