THE INFORMATIONAL SYSTEM IN THE ENTERPRISES OF THE SOUTH-EAST EUROPE
Application software is one of the most important elements of any information system. The most recent trend in the field of the software is, undoubtedly, migration of classic applications from centralized computer architectures to network or distributed architectures. This migration as well as dynamic business environment of an enterprise; need new methods, technique and application development tools. In contrast to classic applications, distributed applications are characterized by their flexibility and adaptability and they are created by modern development tools. Basic types and characteristics of the tools are dealt with in the paper and software base in the enterprises of the South-East Europe and modes of the creation are given at the end.Informational system; Software; Management.

Integrating information and knowledge for enterprise innovation
It has widely been accepted that enterprise integration, can be a source of socio-technical and cultural problems within organisations wishing to provide a focussed end-to-end business service. This can cause possible “straitjacketing” of business process architectures, thus suppressing responsive business re-engineering and competitive advantage for some companies. Accordingly, the current typology and emergent forms of Enterprise Resource Planning (ERP) and Enterprise Application Integration (EAI) technologies are set in the context of understanding information and knowledge integration philosophies. As such, key influences and trends in emerging IS integration choices, for end-to-end, cost-effective and flexible knowledge integration, are examined. As touch points across and outside organisations proliferate, via work-flow and relationship management-driven value innovation, aspects of knowledge refinement and knowledge integration pose challenges to maximising the potential of innovation and sustainable success, within enterprises. This is in terms of the increasing propensity for data fragmentation and the lack of effective information management, in the light of information overload. Furthermore, the nature of IS mediation which is inherent within decision making and workflow-based business processes, provides the basis for evaluation of the effects of information and knowledge integration. Hence, the authors propose a conceptual, holistic evaluation framework which encompasses these ideas. It is thus argued that such trends, and their implications regarding enterprise IS integration to engender sustainable competitive advantage, require fundamental re-thinking
A Shadow-Like Task Migration Model Based on Context Semantics for Mobile and Pervasive Environments
Pervasive computing is a user-centric mobile computing paradigm, in which tasks should be migrated over different platforms in a shadow-like way when users move around. In this paper, we propose a context-sensitive task migration model that recovers program states and rebinds resources for task migrations based on context semantics through inserting resource description and state description sections in source programs. Based on our model, we design and develop a task migration framework xMozart which extends the Mozart platform in terms of context awareness. Our approach can recover task states and rebind resources in the context-aware way, as well as support multi-modality I/O interactions. The extensive experiments demonstrate that our approach can migrate tasks by resuming them from the last broken points like shadows moving along with the users
Algorithms for advance bandwidth reservation in media production networks
Media production generally requires many geographically distributed actors (e.g., production houses, broadcasters, advertisers) to exchange huge amounts of raw video and audio data. Traditional distribution techniques, such as dedicated point-to-point optical links, are highly inefficient in terms of installation time and cost. To improve efficiency, shared media production networks that connect all involved actors over a large geographical area, are currently being deployed. The traffic in such networks is often predictable, as the timing and bandwidth requirements of data transfers are generally known hours or even days in advance. As such, the use of advance bandwidth reservation (AR) can greatly increase resource utilization and cost efficiency. In this paper, we propose an Integer Linear Programming formulation of the bandwidth scheduling problem, which takes into account the specific characteristics of media production networks, is presented. Two novel optimization algorithms based on this model are thoroughly evaluated and compared by means of in-depth simulation results
Appendix To Software Migration: A Theoretical Framework A Grounded Theory approach on Systematic Literature Review
Software migration has been a research subject for a long time. Major research and industrial implementations have been conducted, shaping not only the techniques available nowadays, but also a good part of Software evolution jargon. To understand systematically the literature and grasp the major concepts is challenging and time consuming. Even more, research evolves, and it does based on the assumption that there is a single meaning that we all share redounding in the pollution of words with multiple and many times opposite meanings. In our quest to understand, share and contribute scientifically in this domain, we recognise this situation as a problem. To tackle down this problem we propose a taxonomy on the subject as a theoretical framework grounded on a systematic literature review. In this study we contribute a bottom-up taxonomy that links from the object of a migration t
Patterns and Pathways: Applying Social Network Analysis to Understand User Behavior in the Tourism Industry Websites
The contemporary tourism landscape is undergoing rapid digitization,
necessitating a nuanced comprehension of online user behavior to guide
data-driven decision-making. This research bridges an existing gap by
investigating the tourism website ecosystem through social network analysis. It
focuses specifically on inter-website communication patterns based on user
navigation. Data mining facilitates the identification of 162 core Iranian
tourism websites, which are visualized as an interconnected network with
websites as nodes and user transitions as weighted directed edges. By
implementing community detection, eight key clusters are discerned,
encompassing domains like ticket/tour bookings, accommodations, location
services, and cuisine. Further analysis of inter-community relationships
reveals website groupings frequently accessed together by users, highlighting
complementary services sought during travel planning. The research derives
invaluable insights into user preferences and information propagation within
the tourism ecosystem. The methodology and findings contribute original
perspectives to academia while offering pragmatic strategic recommendations to
industry stakeholders like service providers, investors, and policymakers. This
pioneering exploration of latent user behavior patterns advances comprehension
of the evolving digital tourism landscape in Iran. It contributes pathways
toward a sustainable future vision of the ecosystem, guiding stakeholders in
targeted decision-making based on empirical evidence derived from social
network analysis of websites and consumption patterns. The innovative
methodology expands the toolkit for data-driven tourism research within
academia
