Hierarchical organization - Org chart

"A hierarchical organization is an organizational structure where every entity in the organization, except one, is subordinate to a single other entity. This arrangement is a form of a hierarchy. In an organization, the hierarchy usually consists of a singular/ group of power at the top with subsequent levels of power beneath them. This is the dominant mode of organization among large organizations; most corporations, governments, and organized religions are hierarchical organizations with different levels of management, power or authority. ... Members of hierarchical organizational structures chiefly communicate with their immediate superior and with their immediate subordinates. Structuring organizations in this way is useful partly because it can reduce the communication overhead by limiting information flow; this is also its major limitation." [Hierarchical organization. Wikipedia]
"A company's organizational chart typically illustrates relations between people within an organization. Such relations might include managers to sub-workers, directors to managing directors, chief executive officer to various departments, and so forth. When an organization chart grows too large it can be split into smaller charts for separate departments within the organization. The different types of organization charts include: Hierarchical, Matrix, Flat (also known as Horizontal)." [Organizational chart. Wikipedia]

A four level pyramid model of different types of Information Systems based on the different levels of hierarchy in an organization. The first level represents transaction processing systems for workers. The second level represents management information systems for middle managers. The third level represents decision support systems for senior menegers. The fourth level represents executive information systems for executives.
"The "classic" view of Information systems found in the textbooks in the 1980s was of a pyramid of systems that reflected the hierarchy of the organization, usually transaction processing systems at the bottom of the pyramid, followed by management information systems, decision support systems, and ending with executive information systems at the top. Although the pyramid model remains useful, since it was first formulated a number of new technologies have been developed and new categories of information systems have emerged, some of which no longer fit easily into the original pyramid model.
Some examples of such systems are:
data warehouses,
enterprise resource planning,
enterprise systems,
expert systems,
search engines,
geographic information system,
global information system,
office automation." [Information systems. Wikipedia]
