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.
