What does ETL stand for in data management?

ETL stands for Extract, Transform, Load, which is a critical process in data management, particularly in data warehousing and analytics. This process involves three key steps:

1. Extract: In this initial phase, data is gathered from various sources, which can include databases, CRM systems, and flat files. The extraction process ensures that data from these diverse sources is collected and made accessible for further processing.

2. Transform: After extraction, the data often needs to be cleaned, organized, and transformed to fit the requirements of the target database or data warehouse. This can involve removing duplicates, standardizing formats, merging data from different sources, and enhancing data quality. The transformation step is vital to ensure that the data is meaningful and useful for analysis.

3. Load: Finally, the transformed data is loaded into a target system, typically a data warehouse. This is where the data becomes available for querying and analysis, allowing businesses to derive insights and make informed decisions.

This ETL process is foundational for effective data management, ensuring that high-quality data is available for reporting and analytics. Other options like Enable, Transfer, Log or Edit, Tokenize, Link do not accurately represent the widely recognized and utilized ETL methodology in
