Description: Logical extraction is a process within the ETL (Extract, Transform, Load) framework that focuses on obtaining data based on logical conditions rather than relying on the physical storage of the data. This approach allows organizations to access relevant and specific information more efficiently, as it is based on criteria defined by the user or business needs. Unlike physical extraction, which involves copying data from one system to another, logical extraction focuses on selecting data that meets certain conditions, which can include filters, joins, and other logical operations. This method is particularly useful in environments where the amount of data is massive and the need for agility in decision-making is critical. Logical extraction not only optimizes resource use but also improves data quality by allowing only relevant information to be extracted and utilized. In a world where data is a valuable asset, the ability to perform effective logical extraction has become essential for organizations looking to remain competitive and adapt quickly to changing market conditions.
