How are interfaces in Appian primarily built?

Interfaces in Appian are primarily built using SAIL (Simple Application Interface Language). SAIL is a custom language designed specifically for creating user interfaces within the Appian platform. It enables developers to build dynamic and responsive interfaces that integrate seamlessly with the application's data and logic.

SAIL provides a robust set of components and functions that allow designers to display data, gather input from users, and invoke actions all within Appian's low-code environment. This approach facilitates rapid development while ensuring a consistent user experience across various devices.

In contrast, SQL scripts are mainly used for database queries and are not suitable for designing user interfaces. Java code, though powerful, is not the primary means of constructing interfaces in Appian, as the platform emphasizes low-code solutions over traditional coding. XML documents are also not utilized for interface creation in Appian; they may be involved in data exchange but do not serve as a primary building block for user interfaces.

Overall, SAIL is specifically tailored to meet the needs of interface design within the Appian ecosystem, making it the correct choice for how interfaces are primarily built.
