Abstract

Performanse sustava spadaju u nefunkcijske zahtjeve o kojima uz funkcijske također treba voditi računa. Veliki informacijski sustavi, naime, često imaju uska grla zbog kojih se njihove performanse ne mogu poboljšati jačim hardverom. Jedno od mogućih rješenja je da se nefunkcijski zahtjevi provjeravaju u fazi modeliranja sustava da se izbjegne potreba za ponovnim dizajniranjem i implementiranjem. U tu svrhu su razvijeni alati za simulaciju softverskih arhitektura kao što je Palladio Component Model (PCM). U sklopu ovog diplomskog rada u PCM-u je napravljen pojednostavljeni model jednog web-sustava (TPC-W) koji predstavlja jednu internetsku knjižaru kako bi se performanse modela usporedile s performansama implementacije. Rezultati su pokazali da je pojednostavljeni model sustava dobar za dobivanje okvirne procjene performansi i potvrdili pristup po kojem je dobro ispitati ponašanje modela sustava prije prelaska na implementaciju.

Abstract (english)

System performance is a non-functional requirement which should, along with functional requirements, also be dealt with. Big information systems often have bottlenecks for which their performance cannot be increased with faster hardware. One of the possible solutions would be to check non-functional requirements during system modeling to avoid redesign and reimplementation. For this purpose, software architecture simulation tools, like Palladio Component Model (PCM), have been developed. As a part of this master thesis, a simplified model of a web-based system (TPC-W), which represents an online bookstore, has been developed in PCM to compare the performance of the model with the actual implementation. Results have shown that the simplified model of the system was good enough for obtaining a rough estimate of the system's performance, thus confirming the validity of the model-first approach.
