Sometimes, however, the business case is complex, and it can’t be solved using data files. In such cases, you can use the init hook from the manifest file to perform the operations you want.

Complex business cases may require dynamic initialization of data beyond standard XML or CSV files. Examples include integrating with external systems, performing complex calculations, or configuring records based on runtime conditions, facilitated by the init hook in the manifest file.
