Full File Processing
The Full File processing follows these steps:
-
Load Data from the Database
-
All existing entries are loaded from the database.
-
-
Compare with the Full File
-
Each entry in the Full File is compared with the corresponding record in the database:
-
If the entry exists and matches, no action is taken.
-
If the entry exists but differs, the database record is updated.
-
If the entry does not exist, it is added as a new record.
-
-
Post-Processing Cleanup After processing the Full File, a post-processing hook removes all database records that are not present in the Full File. This ensures that the database remains fully synchronized with the latest Full File contents.
- NOTE
-
Delta file processing is done based on the "change type" flags that are provided by respective industry data source. Details of delta file processing can be found on corresponding industry source specific documents.
