Rules

Rules specify how your data is loaded into Visier.

Overview

Sometimes, data must be changed after it's been loaded in Visier, for example, an incorrect value in the source data or an incompatible data format. Rules allow you to write unique formulas that massage the data to work correctly in Visier.

Rules execute in order: first, the platform runs business rules, then system rules, then multi-subject rules. This gives Visier the ability to make the right transformations at the right time.

• Business rule: Apply transformations to the data, such as adding, removing, or editing events in the event stream. For more information, see Business Rules.
• System rule: Define how to handle subject data, such as adjacent terminations or incorrect parent-child hierarchies. For more information, see System Rules.
• Multi-subject rule: Specify validations and transformations against more than one subject, such as adjusting the validity of data with validity ranges. Multi-subject rules run after business and system rules, so the data has already been transformed or logically configured. For more information, see Multi-Subject Rules.
