Delta load
Data profiling

ETL
ETL stands for Extract, Transform, Load (ETL). This method involves retrieving data, making necessary changes, and loading it into a final destination. Delta load gathers updated records instead of the initial dataset. API data retrieval refers to fetching details through an interface and does not typically include transformations or loading. Data profiling inspects data conditions without shifting it to a different location.
