4. 4 BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Dražen Brđanin, Slavko Marić BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Business model by UML business profile Profile - defined set of standard language extensions, built in UML, and specialized for modeling in particular domain. Business profile (v1.3) specializes base classes of standard UML by introduction of business domain specific classes. Business model = two models business use case model business object model Fig. 1. Business model by UML profile.

BUC is the business process, or some concrete function in business system offered to the exterior systems. BUC is the sequence of actions, preformed by workers in business system, and by them business system makes some concrete and recognable value. Exterior systems are called business actors. Business object model Inside view of business system in the completeness shows process, procedures, business worker's behaviour, used resources (business objects) and their relationships and organization, that goals can be realized and expected results achieved

6. 6 BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Dražen Brđanin, Slavko Marić BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Business use case model BUC model contains descriptions of business actors and BUCs and their interactions, represented by BUC diagrams. Fig. 2. Generic example of BUC diagram. Fig. 3. Generic example of high-level business activity diagram. BUC model also contains realization descriptions of identified BUCs. We can document realization: textually, and graphically (high level activity diagram)

Detailed activity diagram high level activity diagram completed by workers' responsibilities, used objects and object flows Responsibility areas of involved workers are emphasized by swimlanes activity diagram is procedurally (algorithmic) oriented and it’s not appropriate for OO A&D Fig. 6. Generic example of detailed activity diagram.

Generic example of sequence diagram. Fig. 8. Generic example of object diagram. business object model also includes business object (class) diagram shows the static structure and relationships between objects can be used to show organization structure of business system

15. 15 BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Dražen Brđanin, Slavko Marić BUSINESS MODELING BY UML PROFILE: VISA ISSUING SYSTEM Transition from business models to system models Identified BUCs, business actors, business workers and business objects can be used in transition from business models to initial system models. BUC model is transferred in the system UC model, and business object model is transferred in the system design model. Next rules are valid during transition from BUC model to system UC model: each BUC is candidate for system UC, each business actor is possible system actor, each worker is possible system actor. During the transition of business object model next rules are valid: each identified entity (worker or business object) is possible system class, and each message in sequence diagram is possible method of system class. Fig. 13. Transition from business models to system models.

Thanks to very rich notation and semantics, UML business profile offers possibilities for all business domain analysis' aspects. UML based business modeling has especial importance if it's base for IS development. Then, notations for business modeling and system modeling are harmonized, and used concepts offer possibilities for easy transfer business models to system UML models. Described approach of business modeling is illustrated by some parts of business model of Foreigner’s Migration System implemented for government institutions in Bosnia&Herzegovina.
