What is the difference in coding between inserting segments into an existing database and loading a database?
-
The SSA must be qualified
-
There is no difference.
-
The key sequence of the data in loading
-
There is no need for parentage in loading.
-
The PCB processing options
The key difference between inserting segments into an existing database and loading a database is in the PCB (Program Communication Block) processing options. When loading a database, different PROCOPT settings are used compared to inserting segments. The PCB controls what operations are permitted. Other options are incorrect: SSA qualification rules are similar, key sequence matters in both, and parentage is required in both cases.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) The SSA must be qualified - This option is incorrect because it does not address the difference in coding between inserting segments into an existing database and loading a database.
Option B) There is no difference - This option is incorrect. There is a difference in coding between inserting segments into an existing database and loading a database.
Option C) The key sequence of the data in loading - This option is incorrect. The key sequence of the data does not necessarily determine the difference in coding between inserting segments and loading a database.
Option D) There is no need for parentage in loading - This option is incorrect. The need for parentage in loading a database depends on the specific requirements of the database and the relationships between the data.
Option E) The PCB processing options - This option is correct. The difference in coding between inserting segments into an existing database and loading a database can be related to the PCB (Program Control Block) processing options. The PCB defines the access path to the database and can affect how the data is loaded or inserted.
The correct answer is E) The PCB processing options. This option is correct because it highlights the potential difference in coding when dealing with the PCB processing options between inserting segments and loading a database.
