Informatics
Informatics is a branch of information engineering. It involves the practice of information processing and the engineering of information systems, and as an academic field it is an applied form of information science. The field considers the interaction between humans and information alongside the construction of interfaces, organisations, technologies and systems. As such, the field of informatics has great breadth and encompasses many subspecialties, including disciplines of computer science, information systems, information technology and statistics. Since the advent of computers, individuals and organizations increasingly process information digitally. This has led to the study of informatics with computational, mathematical, biological, cognitive and social aspects, including study of the social impact of information technologies.
Public
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the Öffentlichkeit or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, it has suffered in more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder.
Public Administration
Public Administration is the implementation of government policy and also an academic discipline that studies this implementation and prepares civil servants for working in the public service. As a "field of inquiry with a diverse scope" whose fundamental goal is to "advance management and policies so that government can function". Some of the various definitions which have been offered for the term are: "the management of public programs"; the "translation of politics into the reality that citizens see every day"; and "the study of government decision making, the analysis of the policies themselves, the various inputs that have produced them, and the inputs necessary to produce alternative policies."
Public Administration
Public administration is a process or a theory, not merely an accumulation of detailed facts. It is Verwaltungslehre. The object of administrative study should be to discover, first, what government can properly and successfully do, and secondly, how it can do these proper things with the utmost possible efficiency and at the least possible cost both of money and of energy.

Public Administration
Machiavelli was aware of the limitations of technical knowledge; it was not Machiavelli himself, but his followers, who believed in the sovereignty of technique, who believed that government was nothing more than 'public administration' and could be learned from a book.

Public Administration
Much of the pioneering work in organization theory was written about public organizations, or with public organizations in mind. When Weber wrote about bureaucracy, he was thinking of the Prussian civil service. Philip Selznick began his scholarly career writing about the New Deal Tennessee Valley Authority in TVA and the Grass Roots (1953). Herbert Simon’s first published article (1937) was on municipal government performance measurement, and Simon also coauthored early in his career a book called Public Administration (1950) and a number of papers (e.g., Simon, 1953) published in Public Administration Review. Michel Crozier’s classic, The Bureaucratic Phenomenon (1954), was about two government organizations in France.
