The transaction mode determines how database modifications are reflected in your retrievals. The transaction modes are
automatic_transaction
andself_transaction
.Use automatic_transaction mode in the following cases:
● The database is being updated by processes running in parallel to your program, but you are not interested in these updates.
● Your program uses the load and unload functions to change the database contents, and you want to use the updated database in your program each time it changes.Refer to Automatic Transaction Mode for more information,
Use self_transaction mode if your information retrieval is to reflect database changes done by other processes at the same time your program is working, and you do not use load and unload functions in your program. Refer to Self Transaction Mode for more information.
