Full & Incremental Loading in OBIA 7.9.6.4

What is Full Load?
  • Full load means loading data for the very first time onto the BI Apps Data warehouse
  • Full load is also undertaken when data seems corrupt and needs to be cleaned again
  • Data extracted is of huge volume and ETL mappings might run for long duration, often a few days …
  • Data volume controlled by INITIAL EXTRACT DATE parameters
  • Some developers feel full load is the solution to just about any problem, which is incorrect.
 What is Incremental Load?
  • This is the load which customers generally run each day
  • Only the incremental changes in source, compared to previous load are captured and loaded
  • Data volume is low.
  • The Incremental Data Set or the Delta Data is determined mostly by LAST EXTRACT DATE parameter
