Business Rules
• A business rule is a statement that defines or constrains some
aspect of the business.

Business Rules
•
AIRM should include “global” business rules e.g. ICAO airport locator
• The business rules can be derived from the ICAO Annexes and
Documents.
•
However, many business rules will be specific to a particular application
or service.
•
For example:
• ICAO location indicator for an aerodrome is 4 letters
• If the aerodrome has an ICAO four letter location indicator, then this
one will become the CODE_ID for the aerodrome
• An aerodrome can be one of the following types: AH, AD, HP, LS

Business Rule Format: OCL
• The Object Constraint Language (OCL)
• is a declarative language for describing rules that apply to
Unified Modelling Language (UML) models. It is a precise
text language that provides constraint and object query
expressions on any UML model or meta-model that cannot
otherwise be expressed by diagrammatic notation.

Business Rule Format: SBVR
• Semantics of Business Vocabulary and Business Rules
• a means for describing the structure of the meaning of rules
expressed in the natural language that business people and
operational staff use.
• A SBVR rule can easily be machine processed to perform
object rule modelling, perform rule consistency analysis, or
generate formal representations such as OCL constraints,
databases, business rules repositories, business blueprints,
business object models, software components, etc.
