Understanding ELT (Extract, Load, Transform)
Title: Understanding ELT (Extract, Load, Transform): A Vital Concept in Data ProcessingIn the realm of data processing, the term ELT holds significant importance. ELT stands for Extract, Load, Transform, and it refers to the three primary steps involved in moving and manipulating data within a data warehouse or data lake. The first step in ELT is 'Extract', where data is gathered from various sources such as databases, APIs, or files. This process involves extracting raw data in its original format without any alterations.The second step is 'Load', where the extracted data is loaded into a central repository such as a data warehouse or data lake. This step ensures that all the data is consolidated in one location for further processing.Finally, the 'Transform' step involves cleaning, structuring, and organizing the data to make it usable for analysis and reporting. This step may include tasks such as data cleaning, data enrichment, data aggregation, and data modeling.ELT is different f
