Human beings have the distinct ability to attach meaning to whatever they perceive. The data translation to information and attempt, in an organized manner, to provide infor-mation for action, constitute the basis of the principle “information system”. In this course, the notion of an information system in the context of an organization is defined and particular emphasis is placed on the fact that an information system is essentially a kind of system that supports business processes and distributes information to the appropriate receivers using a digital technology as a tool. Professionals in the field of information sys-tems basically work on: a) information generation with the goal to aid the organization define and achieve its goals, and b) the realization or improvement of processes of the organization with the use of appropriate digital technology. Hence, these professionals play an important role in determining the requirements for an information system of the organization and they participate actively in its specification, design and realization. Therefore, they must have deep knowledge of state-of-the-art digital technologies and must be acquainted with the organizational principles and practices so that they contribute decisively in provisioning the systems and information that organization needs for supporting its operations. Furthermore these professionals determine the processes of evolution of information systems in order to achieve novel comparative assets to the organization through interoperability of existing systems and the capitalization from modern digital technology while maintaining existing investments. In this context, the course places particular emphasis to real world case studies on the development of information systems by creating modern web-based and service-oriented architectures.
