Specifikacija aspekata interoperabilnosti u metodološkim pristupima razvoju IS

Abstract

Ova disertacija se bavi problemom specifikacije aspekata interoperabilnosti u metodološkim pristupima za razvoj informacionih sistema. U uslovima opšte globalizacije i savremene saradnje se umesto čvrste integracije teži ka slabom povezivanju organizacionih sistema. Način na koji heterogeni, slabo-povezani sistemi mogu da ostvare efikasne inter-organizacione veze je jedna od aktuelnih tema istraživanja oblasti interoperabilnosti informacionih sistema. Na osnovu analize relevantne literature, imajući u vidu preporuke Advanced Technologies for Interoperability of Heterogeneous Enterprise Networks and their Application (ATHENA) referentnog modela za konceptulnu integraciju, odabrana su tri relevantna aspekta za specifikaciju interoperabilnosti: aspekt procesa, servisa i informacija. U disertaciji se definiše nov specifičan pristup za specifikaciju aspekata interoperabilnosti u metodološkim pristupima za razvoj informacionih sistema. Predloženi pristup je baziran na principima opšteg sistemsko teorijskog modela životnog ciklusa softvera koji ima tri osnovne faze: identifikaciju, realizaciju i implementaciju. Za svaku od faza su precizno definisani opšti koraci i date su preporuke za njihovu primenu. U fazi identifikacije se predlaže da se za specifikaciju inter-organizacionih poslovnih procesa pored funkcionalnog uključi i procesni pogled. U prvom koraku se identifikuju zahtevi za interoperabilnošću koji podrazumevaju specifikaciju: esencijalnih interoperabilnih poslovnih funkcija i poslovnih partnera koji učestvuju u kolaboraciji. Za reprezentaciju kolaborativnog poslovnog procesa je odabrana Business Process Model and Notation (BPMN) notacija. U drugom koraku se definišu opšti dijagrami konverzacije i kolaboracije, dok se u trećem koraku predlaže detaljna specifikacija njihove javne i privatne reprezentacije. U poslednjem koraku faze identifikacije se vrši kreiranje nove ili izbor postojeće referentne ontologije, koja predstavlja osnovu za nedvosmislenu interpretaciju značenja poruka koje se razmenjuju u kolaboraciji.

This thesis addresses the problem of specification of interoperability aspects in methodological approaches to information system development. Under the conditions of general globalization and modern cooperation, instead of firm integration there is a tendency towards weak linking of organizational systems. The manner in which weakly linked systems may achieve efficient inter-organizational connections is one of the up-to-date research topics in the information systems' interoperability domain. Based on the analysis of relevant literature and bearing in mind recommendations of the Advanced Technologies for Interoperability of Heterogeneous Enterprise Networks and their Application (ATHENA) reference model for conceptual integration, three relevant aspects were selected for the specification of interoperability, namely: process, service and informations aspects. This thesis defines a new specific approach to specification of interoperability aspects in methodological approaches for informations systems' development. The proposed approach is based on the „System-Theoretic life cycle“ having three fundamental phases: identification, realization and implementation. For each of these phases general steps have been precisely defined and recommendations for their application given. As for the identification phase, for specification of the inter-organizational business processes it is proposed to include the process view in addition to the functional one. The first step identifies interopebability requirements implying specification of the following: essential interoperable business functions and business partners participating in the collaboration. For representation of the collaborative business process Business Process Model and Notation (BPMN) has been selected. The second step defines general conversation and collaboration diagrams, while the x third step proposes a detailed specification for their private and public representation. The last step in the identification phase implies creation of a new or selection of the existing reference ontology representing a basis for an unambiguous interpretation of the meaning of messages being exchanged in scope of the collaboration.
