Expressions are mathematical calculations that provide information; for example, an expression might summarize the attributes in a module or replace a static date field with the current date. Business rules are advanced expressions that you might use to check the quality of your requirements, implement a complete workflow, or aggregate sales figures for a large corporation.

You can use several default business rules. Each rule has an explanation, a version number, and compilation information. You can upload, export, and delete business rules on the Business Rules page of the Advanced menu. To add, manage, export, or delete business rules, you must either be a global administrator or have the Business rules permission.
