"Full load an initial load both refer to populating a data warehouse table for the first time. The differences with the initial load data is transferred into the data warehouse for the very first time. The table never contained any data. In the full load process, the data warehouse table is first erased to remove any data that was previously loaded, and then the new data is populated in a single batch."

"In the context of data migration, the initial load is the process for populating all data warehousing tables for the first time. Full load also refers to the first time a data warehouse is populated. However, using the full load process, all the records are loaded in one batch after all the contents of the table have been erased."
