You can use the Incremental Load template when you want to identify and capture the data that has been added, changed, or deleted in a database table. The Incremental Load template can be used in the following ways:
Use Last Refresh Time.
You can update the target database by selecting all the rows in a table where the date in the create or modified date fields equates SYSDATE-1.
Use Session Time Stamp
. You can update the target database by loading the latest data based on the session time stamp.
For example, Karen works in a sales environment where the target database is updated at the end of each day to include the whole history of transactions. The database is updated by running a workflow. Karen uses the Incremental Load template to update the target database. This template ensures that only the changed data, and not the entire data, is loaded into the target database.
