ETL (Extract, Transform, Load) Process

ETL stands for Extract, Transform, Load, which is a process used in data management. First, "Extract" involves pulling data from various sources, like databases or spreadsheets. Then, "Transform" means changing that data into a suitable format or structure for analysis, which can involve cleaning or aggregating the data. Finally, "Load" is the step where the transformed data is saved into a storage system, like a data warehouse, making it ready for reporting and analysis. This process helps organizations make informed decisions by ensuring they have accurate and usable data.
