Appian Exam ACD101 Topic 2 Question 19 Discussion

Actual exam question for Appian's ACD101 exam

Question #: 19
Topic #: 2

You are using a local variable in an expression rule to describe the height of an applicant.

Which statement correctly describes the application of Appian best practices for naming your local variable?

Alocal!hoaa - This employs the naming convention of abbreviating 'Height of an applicant' to minimize both the typing required by developers and the length of code Appian is required to parse.

Blocal!applicantHeight - This employs the naming convention of specifically describing the value contained by the variable.

Clocal!x - This employs the naming convention of using algebraic variables for a value that may either change over time or be used by future developers for other purposes.

Show Suggested Answer

Suggested Answer: B

The best practice for naming variables in Appian is to use clear and descriptive names that convey the purpose or content of the variable. Therefore, local!applicantHeight is the best option as it precisely describes the value contained by the variable, which is the height of an applicant. This naming convention aids in readability and maintainability of the code, making it easier for developers to understand and modify the code in the future.

I think option C is also a valid choice, as it follows a common naming convention for variables.

But using abbreviations can make the code less readable for other developers.

Appian devs who use 'local!x' must also prefer their variable names to be as mysterious as their codebase. Just sayin'.

I'm with Dallas on this one. 'local!x' is the coding equivalent of shrugging your shoulders. Let's be better than that.
