Hello @jefrii 

Compute String is commonly used to generate a value dynamically by using the existing schema attribute. This value is generated on run time and it is not saved in schema.

You will notice that all out-of-the-box objects like schema, and input forms use compute string to show data as a combination of label and internal name.

Examples are given here:
