Lithuanian healthcare is highly fragmented enterprise, with complex paper-based processes, that are inefficient, error prone, and often redundant. These shortcomings create formidable barriers to collaborative medical research. This paper is a research of Service Oriented Architecture solutions for solving interoperability problems when exchanging patient data between heterogeneous healthcare systems. The Lithuanian healthcare information needs analysis was made to create the Service Oriented Architecture based model for exchanging patient data. The model prototype was developed to demonstrate the reusability and flexibility of service oriented solutions.

Daugėjant informacijos ir paslaugų kiekiui internete tradicinės elektroninio mokymo architektūros vis sunkiau patenkina iškylančius integracijos, išplėtimo, resursų valdymo poreikius. Nauja paslaugom orientuota architektūra, įgyvendinama žiniatinklio paslaugų technologijomis bei Grid aplinka yra tinkamas būdas efektyviam ir kokybiškam e-mokymui užtikrinti. Šiame darbe nagrinėjama kokias naujas galimybes e-mokymo srityje atveria paslaugom orientuota Grid architektūra. Tam kad būtų galima pasinaudoti naujomis galimybėmis turimą sistemą reikia modifikuoti. Pateikiamos rekomendacijos egzistuojančios interaktyvios e-mokymo taikomosios programos adaptacijai Grid paslaugų architektūrai. Šios rekomendacijos realizuoja esamą sistemą kaip paslaugą ar paslaugų rinkinį. Sudarytos rekomendacijos praktiškai išbandomos pritaikant realią nuotolinę testavimo sistemą Grid paslaugų aplinkai. Eksperimentinėje dalyje yra įvertinta nauda, kurią suteikia sistemos realizavimas Grid paslaugomis išplečiamumo, lankstumo bei pakartotinio panaudojimo požiūriu. / The increasing amount of information and services on the internet continues to grow, traditional e-learning architectures are unable to satisfy the need of integration, flexibility and resource management. The new service oriented architecture based on web services technologies and Grid environment is the effective and valuable way to develop e-learning. In this master thesis new e-learning opportunities based on service oriented Grid architecture are analyzed. In order to use new approaches the existing system has to be modified. Recommendations for the existing interactive e-learning applications adaptation for the service oriented Grid environment are presented. These recommendations implement the current systems as a service or set of services. The proposed recommendations are tested practically adapting the real distant assessment system for Grid service environment. The added value of this new approach is evaluated taking into consideration scalability, flexibility and reusability of Grid services in the experimentation part.
