Answer :
When data needs to be transformed to match the target system's requirements, data transformation is utilised.
Data transformation, in computing, is the process of changing data from one format or structure into another format or structure so that it may be used, cleaned up, and organised into a format that can be analysed to assist decision-making processes and to fuel the growth of a business. It is a crucial component of the majority of data management and integration jobs, including application integration, data wrangling, data warehousing, and data integration.
Depending on the required modifications to the data between the source (initial data) and the destination (final data), data transformation can be straightforward or difficult. The process of transforming data typically involves both manual and automated steps.
