Which of the following is true about the entry ID?

The entry ID is a unique identifier that is assigned to each individual entry or record within a specific context, such as comment posts or other data entries in an application built with Appian. The key aspect of the entry ID is that it is designed to be non-reusable. Once an entry ID is created and assigned to a particular entry, it remains associated with that entry for its lifetime. This ensures that each entry can be unambiguously referenced and prevents confusion that could arise from reusing IDs for different entries, which could compromise data integrity and tracking.

In contexts where data might change, having a unique and non-reusable entry ID allows developers and users to reliably manage and interact with data without the risk of inadvertently mixing up entries. This design decision enhances the system's robustness and reliability in handling data operations. Other choices don’t reflect the intrinsic nature of entry IDs or their requirements effectively.
