Introduction to ETL Optimization
ETL embodies a structured method for consolidating vast amounts of data from various sources into a central repository, typically a data warehouse. Using a diverse array of ETL tools and methodologies, this process applies predefined business rules to refine, organize, and prepare raw data for essential functions such as data analytics, storage, and machine learning (ML) applications. Whether you're a BI engineer, data analyst, ETL developer, or data engineer, understanding ETL's various applications and scenarios is crucial. It empowers you to fully utilize ETL's capabilities within your organization, optimizing data usage. This article aims to explore the myriad use cases of ETL and highlight its pivotal role in driving success in data-centric enterprises.
