Which of the following features is NOT part of Appian's functionality?

The functionality of Appian primarily revolves around process automation, task management, and business application development. Task assignment to users is a core aspect of workflow management within Appian, enabling efficient handling of business processes by distributing tasks among users. Document management capabilities are integral to storing, retrieving, and collaborating on documents as part of these workflows. Robotic process automation is also supported within Appian, allowing users to automate repetitive tasks and integrate with other systems, enhancing overall operational efficiency.

In contrast, while Advanced database analytics can be performed through external tools and services, this specific functionality is not a core feature of Appian itself. Appian provides integration capabilities that allow users to connect to databases and perform various operations, but it does not specialize in advanced analytics within the platform. Therefore, this distinguishes it from the other features listed, which are fundamental to Appian's offerings.
