Magistro darbo objektas – elektroninių informacinių technologijų (toliau – informacinių technologijų) integracija. Darbo tikslas – informacinių technologijų integracijos proceso analizė bei tendencijų išskyrimas. Pagrindiniai darbo uždaviniai: aptarti požiūri į informacinių technologijų integraciją, kuriuo vadovaujamasi darbe; nustatyti informacinių technologijų integracijos barjerus; išskirti informacinių technologijų integracijos lygius; atlikti informacinių technologijų integracijos analizę pagal išskirtus informacinių technologijų integracijos lygius. Informacinių technologijų integracija yra ypatingai dinamiška ir sudėtinga sritis, todėl būtina ją nuolat nagrinėti. Būtent dėl šios priežasties tiek mokslinėje, tiek populiariojoje literatūroje vyrauja skirtingi šio proceso nagrinėjimo būdai bei požiūriai į jį. Dažnu atveju apsiribojama vienu ar keliais proceso aspektais arba kalbama ypatingai abstrakčiai, naudojamos skirtingos proceso sampratos ir apibrėžimai, trūksta standartizacijos, vyrauja populiarusis požiūris į integracijos procesą, kuris nėra išsamus ir negali atsakyti į visus iškylančius teorinius klausimus. Pagrindiniai darbo teiginiai, kurie įrodinėjami darbe yra šie: egzistuoja du, vienas nuo kito santykinai izoliuoti, informacinių technologijų integracijos lygiai; egzistuoja skirtingos šių lygių integracijos tendencijos; tarp šių lygių vyksta palaipsninė substitucija; Dėl informacinių technologijų gausos, darbe nagrinėjama tik elektroninių informacinių...

Purpose – information technology process analysis and exclusion of trends. Main tasks: discussion of views towards information technology process and the exclusion of the view used in the work; find and examine information technology integration barriers; separate information technology integration levels; examine information technology integration according to the separated integration levels. Information technology integration is extremely dynamic and complex area, there fore it needs to be examined all the time. Due to that existing different views and analysis of the process among different specialists - most of the time process’s analysis is limited to one or few aspects or it is analyzed abstractly. Most of the time in different analysis types different views and terms occur, lack of standardization is obvious, popular view, which can’t answer all theoretical questions that come out to surface, is dominant in the area. Work‘s main propositions, which are proven in the work: two partially separated integration levels exist; different trends can be applied to them; process of substitution is the way of interaction between these two levels. Due to the high amounts of information technology, only electronic ones are analyzed in the work. This work might be useful to technological and physical scientists, management and communication specialists, students and teachers.
