Every document within the data warehouse was loaded as part of a group of documents. This set of documents is identified by a load-id (integer value). There are 3 types of load-ids in the data warehouse: (1) created-load-id, (2) deleted-load-id, (3) and modified-load-id. The created-load-id represents the load-id in which a document was added to the database, the modified-load-id represents the load-id that last modified the document, and the deleted-load-id represents the load-id in which the document was marked as deleted. For a thorough understanding of load-id(s), please see the blog Sorting Through Data Warehouse Updates. |
