The nature of Web system development is significantly different from conventional software development. Good method for system development is needed. Analysis show, that main known system development methods are good at describing static web application aspects, but does not provide a good description for modeling web application behavioral characteristics. This work uses model driven approach as one, suitable for dealing with web application development problems. The key aspect of model driven approach is specifying system domain model independent of any particular technology (J2EE, Microsoft .NET, etc.) and then generating platform specific model or its implementation. The UML is user-friendly, easy to use and is useful for describing system effectively. Specification expressed in terms of UML can be rendered into an XML document using the OMG’s XMI DTD for UML, which makes UML suitable for model driven approach implementation. In this work, method for specifying application behavior design using UML was presented. This method gives rules for specifying web application behavior model, suitable for its implementation code generation. The main components used in today’s web application which implementation could be generated from the model were also described. It was shown, that it is possible to generate much of implementation, just using such a model representation in XMI. The main idea presented in this work is that web application development should be model driven as... [to full text]

Kuriant sistemą, kuri turės sąsają internete, reikia turėti metodiką, kuria būtų galima vadovautis projektuojant šią sąsają. Objektinio projektavimo metoduose ir unifikuotame kūrimo procese RUP (angl. Rational Unified Process) nėra aprašytų specialių procesų interneto sąsajai kurti. Nors šia tema rašė nemažai autorių, tačiau sunku rasti vientisą metodiką, kuria galėtų vadovautis interneto sąsajos ir ja paremtos sistemos kūrėjas. Šiame darbe tiriami esami interneto sistemų sąsajos projektavimo metodai, šablonai bei įvairios kūrimo technologijos, siekiant juos sukonkretizuoti, apibendrinti ir sukurti metodinę medžiagą, kurią būtų galima taikyti interneto sistemas projektuojančioje organizacijoje, mokymo procese ar pateikti kaip gidą, bet kuriam interneto sąsajos projektuotojui. Šiais laikais kompiuteriai dalyvauja daugelyje sričių, ir bendravimas tarp žmogaus ir kompiuterio neišvengiamas. Kad vartotojas galėtų valdyti sistemą, šis bendravimas vyktų sklandžiai, reikalinga sąsaja. Esamos sistemos turi sąsają, tačiau susistemintos metodikos, kaip reikėtų kurti tą sąsają, nėra daug, ji išsklaidyta atskiruose literatūros šaltiniuose ar interneto puslapiuose. Dažnai ši metodika slypi projektuotojų mintyse, bet ji taip ir lieka neaprašyta ir pats sąsajos projektavimas būna intuityvus. / Nowadays, information system creation process consists of several different actions, one of those actions – web interface design. Web interface design process requires a good methodology, to make web interface process better, quicker, flexible and satisfy other web interface design criterions. RUP (Rational Unified Process) don’t present any special creation process of internet web interface. Frequently web interface design process lies in the head of it’s designers. There are no full methodology of web interface design process in one place, only some web interface advices or articles about one or other web interface process steps could be found. The goal of this work is to make a methodology of web interface design and implement it for internet service provider system. Methodology also would be useful for companies which participate in web interface design process, also in school or university study process, or like a guide for any web interface designer. The developed methodology for web interface design was used for implementing internet service provider system web interface, system design process and redesign above-mentioned system web interface for measuring process times. Methodology of web interface design, reduce web interface design process time, help to make web interface design process easier, more flexible and understandable for web interface designer, also certain better web interface appearance independence from system functional part, with possibility to...
