Abstract

Programska arhitektura zasnovana na uslugama omogućuje jednoobrazno povezivanje raznorodnih programskih sustava te brzu i jednostavnu izgradnju raspodijeljenih programskih sustava. Programski model zasnovan na uslugama je krajnjim korisnicima prilagođen model izgradnje raspodijeljenih programskih sustava zasnovanih na uslugama. Sustavi oblikovani prema načelima programskog modela zasnovanog na uslugama izgrađuju se od primjenskih mrežnih usluga, usluga suradnje i natjecanja te raspodijeljenih programa. Raspodijeljeni programi koriste funkcionalnosti primjenskih mrežnih usluga te uporabom usluga suradnje i natjecanja definiraju koordinacijsku logiku cjelokupnog raspodijeljenog programskog sustava.
U magistarskom radu opisan je korisnički jezik SSCL ( Simple Service Composition Language ) za izgradnju raspodijeljenih programa. Izgradnja raspodijeljenih programa u jeziku SSCL prilagođena je krajnjim korisnicima računalnih sustava koji imaju ograničena znanja i iskustva o tehnikama programiranja. Jezik SSCL oblikovan je prema načelima skriptnih programskih jezika i isključivo je namijenjen povezivanju funkcionalnosti mrežnih usluga. Zbog ograničene primjene i malog skupa naredbi, sintaksna i semantička pravila jezika SSCL su vrlo jednostavna čime je proces učenja jezika skraćen i prilagođen korisnicima bez prethodnog iskustva u programiranju. U radu je na nizu primjera uzoraka tijeka izvođenja provedena analiza izražajnosti jezika SSCL, a dobiveni rezultati pokazuju dobru izražajnost unatoč malom skupu naredbi jezika. Prevođenje raspodijeljenih programa napisanih u jeziku SSCL ostvareno je raspodijeljenim sustavom prevođenja. Raspodijeljeni sustav prevođenja ostvaren je u skladu s načelima arhitektura zasnovanih na uslugama čime je omogućena njegova uporaba u raznorodnoj okolini mreže Internet.

Abstract (english)

Service Oriented Architecture (SOA) promotes services as basic building elements for rapid development of distributed applications and integration of heterogeneous systems. Serviceoriented programming model (SOPM) is well-suited for end-user development of serviceoriented applications. Service-oriented applications developed using SOPM consist of application services, distributed programs, and coopetition mechanisms. Distributed programs utilize application services and define overall application's coordination logic by using functionalities of coopetition services.
The master thesis describes an end-user service composition language named Simple Service Composition Language (SSCL) that enables development of distributed programs. SSCL language is well-suited for end-users that are not familiar with programming languages and have little experience with programming techniques. SSCL language is based on principles of script languages and its only purpose is description of service composition logic. As SSCL language is a domain specific language with small statement set, its syntax and semantic rules are simple. Simplicity of the language improves the language learning process and adapts it to end-users. As a part of the master thesis, the expressiveness of the SSCL language was analyzed by implementing a set of workflow patterns. The results of the analysis show that the SSCL language is highly expressive regardless of its simplicity. Distributed programs written in SSCL language are translated to interpretable language by distributed translation system. Distributed translation system is designed according to SOA principles and is implemented using standard Web Services technologies. Service oriented implementation enables execution of translation system in heterogeneous environments such as Internet.
