Module 5: Extended Data Types

Justification:

1. True: This statement is true. Extended data types extend a primitive data type, like a string for example. It then has additional properties set on that data type, such as a set field length.

Justification:

1. True: This statement is true. EDTs offer many benefits, such as reusability and easier code navigation and reduce overall work. They should be used whenever possible.

Justification: Option B, C, D

1. EDTs are compiled and transferred in the same way as any primitive data type or system element.
2. EDTs are reusable in the system. For example, the AccountNum EDT can be used in a variety of areas in the system.
3. EDTs can be referenced in code by name. This makes reading the code easier to understand and decipher.
4. EDTs have inherited properties and can be used in a hierarchical format. This way, you can reuse and inherit the properties you desire, and change others. Reuse of EDTs also provides more consistency.

Justification:

• A. Correct: EDTs are compiled in the same way as any primitive data type.
• B. Incorrect: EDTs are reusable throughout the system.
• C. Incorrect: The code is easy to read for EDTs because they are referenced by name.
• D. Incorrect: EDTs inherit properties from their parent and can be used in a hierarchical format.

• A. Incorrect: The string data type does not limit the variable to a defined list.
• B. Correct: The enum type allows you to use a defined list of values.
• C. Incorrect: The integer data type does not allow string characters.
• D. Incorrect: The container allows you to hold multiple values of different data types. It does not limit you to a defined list.
