Loading Strategies
In the realm of general data warehousing, various loading strategies come into play. One prevalent challenge often encountered is the absence of deleted records within a delta. In typical data warehousing scenarios, it becomes crucial to recognize and track deletions from the source system, often referred to as soft deletes.
The distinction lies in the need to not only capture new or modified data (delta) but also to account for records that have been deleted at the source. Soft deletes involve marking records as deleted rather than physically removing them, allowing for a more nuanced and traceable approach to data management.
