Extract: This step involves collecting data from various sources such as databases, CRM systems, flat files, and APIs. The goal is to gather all relevant data that will be used in subsequent steps. Transform: During this phase, the extracted data is cleaned, converted, and formatted to meet the requirements of the target system. This may include filtering out duplicate records, standardizing data formats, and applying business rules. Load: The final step is to load the transformed data into a destination such as a data warehouse, data mart, or another database. This ensures that the data is ready for analysis and reporting.
