Viena labiausiai paplitusių internetinių informacinių sistemų rūšių yra intranetas. Tai organizacijos tinklas, grindžiamas interneto protokolų rinkiniu TCP/IP. Pagrindinė intraneto paskirtis – komunikacija ir bendradarbiavimas tarp organizacijos narių, ir paprastai kiekvienas jų, priklausomai nuo savo atliekamų funkcijų, turi skirtingas naudojimosi intranetu teises. Magistrinio darbo tikslas - sukurti informacinę sistemą „Ei-tinklas“ gimnazijoje – intranetą – kaip vieną iš priemonių, skirtų šiuolaikinei vadybai bei mokymui(-si), realizuoti. / One of the most prevalent types of Internet Information Systems is Intranet. It is an organization network based on the collection TPC/IP of internet records. The main purpose of the Intranet is communication and cooperation among members of an organization, and usually each of them, depending on their accomplishing functions, has different rights of the Intranet’s usage. The aim of Master Degree Work is to create an information system “Ei-network” in the gymnasium – Intranet – as one of the means designed for implementing modern management and teaching (learning).

The identification of personality adequacy includes complete research of a person. There are various psycho diagnostic testing methods for such researches. The most testing methods are being created abroad, therefore it takes a lot of time to evaluate the results and to adapt them to the Lithuanians situation. This means that the psychologist have to make a lot of tests of different patient’s groups as well. At the moment, there is no program in Lithuania, which would be helpful by creating computerized version of tests and able to collect all data related to the patient and to the process of theinvestigation. Such program would be able to computerize confidential methods as well. All data related to the patient and the method of research, has to be protected. The information system of personality adequacy identification gives a possibility for the psychologists to register the investigative persons and the process of this investigation. It also helps to create textual and visual tests, to test the investigative persons, to accumulate the diagnosis and the experience of the applied methodic. The created system of programs helps the psychologists to work more efficiently and to generalize the date of Lithuanian’s patients groups as well. This program is going to ensure the required grade of confidentially and security of tests data.

The current work has arisen with respect to the growing importance of ontology modelling in Information Systems development. Due to emerging technologies of Semantic Web, it is desirable to use for this purpose the Web Ontology Language OWL. From the other side, the relational database technology has ensured the best facilities for storing, updating and manipulating the information of problem domain. This work covers analysis of the process how ontology of a particular domain described in OWL may be transformed and stored in a relational database. The algorithms for transformation of domain ontology, described in OWL, to relational database are proposed. According this algorithm, ontology classes are mapped to relational tables, properties to relations and attributes, and constraints – to metadata. The proposed algorithm is capable to transform all OWL Lite and part of OWL DL syntax. The further expansion of the algorithm to cover more capabilities of OWL should be based on the same principles. The prototypical tool, performing transformations, has been implemented as add-in for the ontology development tool “Protégé����. The methodology of transformation is illustrated with an example.

Kasdieninis žiniatinklio informacinių sistemų (toliau – IS) naudojimas paprastų vartotojų, verslo ir vyriausybinių organizacijų tarpe, reikalauja vis aukštesnės tokių IS kokybės. Žiniatinklio IS dažniausiai yra tokia programinė įranga, kurios sudėtingumas, dėl keleto apjungiamų technologijų, yra aukštas, o pokyčių greitis yra didelis. Vykdant palaikymo ir priežiūros darbus, gali atsirasti begalė klaidų, kurias iššaukia atlikti pakeitimai. Regresinio testavimo paskirtis yra užtikrinti, jog įdiegus programinės įrangos pakeitimus, tokius kaip naujo funkcionalumo pridėjimas ar jau egzistuojančio taisymas, ankstesnėje IS versijoje veikęs funkcionalumas veiks taip pat gerai ir naujojoje versijoje. Šiame darbe tiriami iš HTML žymų sudarytą IS atsaką galintys palyginti regresinio testavimo algoritmai (toliau – testų orakulai). HTML ãtsako kaip teksto lyginimas pateikia per daug klaidingai teigiamų (angl. false positives) rezultatų – testuotojas užverčiamas pranešimais apie netikras klaidas. Mūsų realizuotas testų orakulas HTML žymų atsaką nagrinėja kaip medžio struktūrą. Toks algoritmo veikimas leidžia tikrinti arba netikrinti aprašytas HTML semantines savybes, ko pasekoje yra sumažinamas klaidingai teigiamų ir klaidingai neigiamų rezultatų kiekis. Realizuotas testų orakulas nuo literatūroje aprašomų ir rinkoje siūlomų testų orakulų skiriasi tuo, jog nepraneša apie klaidą, kai HTML atsakas būna papildytas naujomis žymomis, kurios nekeičia pradinės medžio struktūros. Žiniatinklio IS... [toliau žr. visą tekstą] / Common usage of web information systems among consumers, business and governmental organizations require higher quality of such systems. Web information systems is such a software, which has high complexity because of the multiple technology usage and tends to rapid changes. Errors may occur because of the changes that have been made through maintenance period. Regression testing purpose is to ensure, that software changes such as new functionality or previously existed functionality modification, did not affect functionality, which was well working in the older version. In these master thesis we analyze test oracle comparators which can compare HTML response. HTML as a text comparison produces too many false positives. Meanwhile our test oracle comparator analyses HTML response as is was a tree structure. Thus implementation of the test oracle comparator algorithm enables opportunity to validate or not to validate described HTML semantic features. Therefore, we get fewer false positives and false negatives. Our implemented test oracle comparator differs from the ones described in literature or the ones proposed in market by capability not to warn tester about changes such as newly added HTML tag, which do not change overall tree structure. In this way the introduction of natural functionality growth is allowed. After improvement our test oracle comparator detects 90 % errors with the 90 % precision, whereas in the market existing test oracle comparator of the regression... [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.
