Steps involved in the data transformation process
ETL is an acronym for Extract, Load and Transform and it refers to the entire data transformation process. Analysts can convert data to the desired format using the ETL process. Here are the steps involved in the data transformation process:
Data discovery: The first stage involves analysts attempting to comprehend and identify data in its original format and they accomplish this through the use of data analysis tools. This step assists analysts in determining the steps necessary to convert data to the desired format.
Data mapping: Analysts perform data mapping during this phase to identify how to modify, map, filter, join and aggregate individual fields. Numerous data processes require data mapping and a single error can result in inaccurate analysis.
Extraction: This phase involves the extraction of data from its actual source. These sources may be structured, like databases or streaming, such as customer log files from web apps.
Execution: Analysts write code to complete the transformation after the data extraction. They often use ETL tools to create codes.
Review: After data transformation, analysts check the data to ensure the correct formatting of everything.
Sending: The last step is to send the data to its intended location. The destination can be a data warehouse or a database that manages data.
