The objective of the course is to introduce basic concepts and techniques related to business analysis of IT enabled work systems. The students will comprehend how different types of business processes and technologies, within a specific human, work and organisational context can be analysed in order to identify and implement improvements and innovations. Emphasis is given on techniques for the analysis of structures, performance, infrastructures and risk in organisational and societal settings empowered by technology. Further, the student will be introduced to techniques and tools for business process modelling and evaluation and will apply them to test cases in lab sessions. Students will also learn how to conduct a business process analysis study and will be asked to apply these skill in ta real life case setting. The course material includes the following thematic areas: • Organizational analysis and Information Systems • Work systems: conceptual framework, elements of, and 5 analysis perspectives • Event driven business process modelling • Work systems analysis perspectives: architecture, performance, infrastructures, context, and risk. • Applying business analysis techniques to real-life settings • Business process management life-cycle.

The services domain concerns the largest business sectors both internationally and in our country, among which stand out the sectors of Financial and Insurance business, the tourism industry, this communication, the entertainment industry, sports and other important business-to-business (b2b) sectors. Furthermore nowadays in all products [goods] sectors accompanying / supporting services related to goods are evident.

This course covers the basic concepts of distributed systems (principles, components, design approaches, implementation issues) , allowing students to gain an understanding of the capabilities offered and the problems faced by contemporary distributed. Systems. After an introduction to distributed systems (models), the course covers basic implementation issues (networking, multithreading, remote method invocation, security mechanisms) as well as basic issues in distributed processing (leader election, distributed transactions). Then, the course covers the basic concepts of peer to peer systems (structured systems, routing) and their applications (content search, multicast), presents some distributed services (distributed naming, distributed storage) and finally examines higher level communication facilities (message oriented middleware, web services). The applied part of the class focuses on the facilities provided by Java for programming distributed systems and the implementation of distributed applications. The programming project of the course involves the implementation of an structure peer to peer system for file searching using remote objects.
