The business semantic model

The business semantic model (or aspect) concentrates only on the objects at the very heart of the activity. The fundamental core is described, this core being independent from the way in which the activity is conducted, in other words, the business. These objects are called business objects in certain approaches.

Icon	Name	Description	Example
	Business Semantic	Model containing elements relative to the semantic aspect.	Entreprise Model
	Domain	Group of fundamental business objects, semantically close, focusing on one or several principal objects.	Catalog Management
	Semantic class	Businesss object.	Contract, Account
	Semantic attribute	Property of a business object.	Name, adcress
	Semantic operation	Operation carried out on the business object.	open an account(), credit an account()
	Primitive type	Basic types whose occurrences have no individual identity of their own.	Date, unlike "Account", which is not a primitive.
	Enumerated type	Enumeration.	traffic light – green orange red
	Signal	Describes a type of event whose occurrence can trigger processing or modify operations in progress.	Order Cancellation
	Operation pre and post conditions	Pre-condition: necessary conditions that must be respected before the operation. Post-condition: condition obtained after the operation.	debitAccount() Pre: sufficient balance Post: balance reduced by debited sum
	Invariant, Business rule	Fundamental rule directing the business. Applies to a semantic class: condition that must always be respected.	An account whose holder has died must be placed under administrative supervision.
	Constraint	Rule that applies to the designated model elements.
	Sending/Receiving a signal	Defines which class sends or receives signals.	Order receives "Order Cancellation"
	Inheritance (generalization)	Specialization link betwee classes. Definition of a taxonomy of semantic classes.	ShortTermContract and LongTermContract both inherit from Contract.
	Dependency, import	Determines that an element (object domain, semantic class) relies on another element for its definition.	"Sales Management" object domain imports "Clients and Services" object domain.
	Association	Association between semantic classes. Stable liaisons involved in the definition of these classes.	"beneficiary" association between Client and Stay
	Traceability	Defines that the definition of a notion derives from a notion.	"recommendation" attribute drawn on the "consideration of client recommendations" requirement

Business semantic model diagrams

There are three types of business semantic model diagram:

· Class semantical diagrams

· Domain semantical diagrams

· State diagrams of semantic classes

Class semantical diagrams

The following image is an example of a class semantical diagram. This type of diagram is created in a semantic domain using the icon.

Example of a class semantical diagram: Business model

Domain semantical diagrams

A domain semantical diagram presents domains that group business concepts. This type of diagram is created in the model or in a semantic domain using the icon.

Example of a domain semantical diagram

State diagrams of semantic classes

A state diagram of a semantic class is created inside a semantic class using the icon.
