4 Level pyramid model diagram - Information systems types

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]

The triangle chart example "Information systems types" is included in the Pyramid Diagrams solution from the Marketing area of ConceptDraw Solution Park.

The vector stencils library "Workflow diagrams" contains 54 symbol icons for drawing the work flow charts.
Use these clipart to represent information flow, automation of business processes, business process re-engineering, accounting, management, and human resources tasks in industry, business, and manufacturing.
"A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, declared as work of a person or group, an organization of staff, or one or more simple or complex mechanisms.
From a more abstract or higher-level perspective, workflow may be a view or representation of real work, thus serving as a virtual representation of actual work. The flow being described may refer to a document, service or product that is being transferred from one step to another.
Workflows may be viewed as one fundamental building block to be combined with other parts of an organisation's structure such as information silos, teams, projects, policies and hierarchies." [Workflow. Wikipedia]
