Visual languages are used for understandability of business analysis, modeling and computerization processes for business analysts as soon as system developers. The advantages of visual modeling are standard notation, unified concepts, and intuitive use. There is no single language suitable for all phases of business process evolution. Three languages were analyzed: UML 2.0, BPMN and BPEL4WS, with regards to their possibilities to represent and execute e-business processes. It is proposed to extend UML 2.0 with BPMN stereotypes for e-business process modeling with succeeding transformation to execution language BPEL. The exclusive feature of proposed way of modeling lies in integration of business process model with object types of problem domain. In order to test the proposed method, scenario for modeling was prepared and three models were designed: two models using UML 2.0 notation, and one model using UML extended with BPMN stereotypes. Models were compared to show new method advantages. For implementation of proposed method, UML CASE tool MagicDraw was extended with stereotypes required for the proposed method of modeling. Extended user interface was proposed for specification of business rules governing the e-business process.

Elektroninio parašo panaudojimo galimybės bei nauda nenuginčijami. Praėjo daugiau nei aštuoni metai nuo to kaip Europos parlamentas ir Europos Sąjungos taryba priėmė direktyvą dėl Bendrijos elektroninių parašų reguliavimo sistemos. Po šios direktyvos priėmimo tiek Lietuvoje tiek visoje Europoje sekė įstatymai, reglamentuojantys elektroninio parašo naudojimą nacionaliniame lygmenyje. Taip pat sekė standartų tvirtinimas tam, kad būtų išvengta nesuderinamumų. Darbe yra apžvelgiama dabartinė Lietuvos padėtis taikant elektroninį parašą elektroninėje valdžioje bei komercijoje, remiantis paskutiniu metu atliktais tyrimais Lietuvoje ir Europoje. Darbas yra suskirstytas į keturias pagrindines dalis. Pirmojoje dalyje yra išanalizuoti metodai, kuriais yra remiamasi formuojant elektroninį parašą ir kaip šie metodai užtikrina, jog elektroninis parašas yra apsaugotas nuo klastojimų. Antroje dalyje apžvelgiama elektroninio parašo teisinis reglamentavimas Lietuvoje. Trečioje išanalizuojamas praktinis Lietuvos ir kelių Europos valstybių praktinis pasiruošimas. Ir ketvirtoje dalyje aprašyti atlikti tyrimai. Viename iš jų įvertinama kaip Lietuvos valstybinės institucijos yra pasiruošusios priimti elektroninius dokumentus, pasirašytus e. parašu. Antrame tyrime atliktoje apklausoje yra įvertinama koks šiuo metu yra visuomenės susipažinimo lygis su elektroninio parašo infrastruktūra. / Electronic Signature‘s benefit is obvious.
