Business Rules

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

Example: Syntactical Rules

• What is the size of the designator?

• Example syntactical rule:OCL:

{ IdAerodrome.code -> size >= 3 and IdAerodrome.code -> size <= 6 }

Airportdesignator: CharacterString

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.
