What type of variable is used to store multiple values in Appian?

In Appian, an array is a variable type designed specifically to hold multiple values. This allows developers to store a collection of items of the same data type in an indexed structure. For example, if you need to store a list of user names or numerical scores, an array would enable you to manage these values efficiently as a single variable, rather than needing to create separate variables for each item.

Arrays can simplify data manipulation, especially when performing operations like iteration, sorting, or filtering. Using an array, you can easily access and modify individual elements based on their index, making it a powerful tool for handling sets of related data in your applications.

In contrast, other variable types, such as dictionaries, integers, and text, are designed for single-value storage or specific use cases. A dictionary stores key-value pairs, an integer holds a single numeric value, and text is used for storing a single string of characters. Therefore, when you need to manage multiple values, arrays are the appropriate choice in Appian.
