The course provides a first cognitive approach to Information Systems as a tool for exercising operational management of businesses and organizations. The course content covers the basic concepts of administrative operation in the context of digital reality. Initially, the concepts of the technological dimensions of information systems are covered (hardware, software, information, databases, telecommunications, security). Then, through case studies, their potential operational applications are presented, as well as the prospects of developing and managing management information systems. Emphasis is placed on the concepts of e-business and digital markets in the light of an operational global economy. The basic discussion of the concepts is completed with the correlation of information systems and decision-making processes, with the aim of achieving competitive advantage in an environment of international competition. Finally, the ethical and social issues that arise, particularly in the context of evolving artificial intelligence technology, are presented, as well as the multiplying possibilities that arise from the development of these new technological capabilities.
