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]

A five level pyramid model of different types of Information Systems based on the information processing requirement of different levels in the organization. The first level represents transaction processing systems to process basic data. The second level represents office support systems to process information in office. The third level represents management information systems to process information by managers. The fourth level represents decision support systems to process explicit knowledge. The fifth level represents executive information systems to process tacit knowledge.
"A Computer(-Based) Information System is essentially an IS using computer technology to carry out some or all of its planned tasks. The basic components of computer based information system are:
(1) Hardware - these are the devices like the monitor, processor, printer and keyboard, all of which work together to accept, process, show data and information.
(2) Software - are the programs that allow the hardware to process the data.
(3) Databases - are the gathering of associated files or tables containing related data.
(4) Networks - are a connecting system that allows diverse computers to distribute resources.
(5) Procedures - are the commands for combining the components above to process information and produce the preferred output.
The first four components (hardware, software, database and network) make up what is known as the information technology platform. Information technology workers could then use these components to create information systems that watch over safety measures, risk and the management of data. These actions are known as information technology services." [Information systems. Wikipedia]

This flowchart example was created on the base of land sales process diagram from the Property management webpage of the VicRoads website.

"VicRoads or the Roads Corporation of Victoria is a statutory corporation which is the state road and traffic authority in the state of Victoria, Australia. It is responsible for maintenance and construction of the state arterial road network, as well as driver licensing and vehicle registration. VicRoads has broad responsibility for road safety policy and research. It is also responsible for regulating the accident towing industry in Victoria." [VicRoads. Wikipedia]
"Sales Process.
Once it has been established with the relevant VicRoads Regions/ Projects and other business areas that properties are identified as surplus to VicRoads’ operational needs, they are incorporated in the VicRoads annual sales program.
Following approval: relevant VicRoads Regional Manager and the VicRoads Chief Executive (and in some circumstances Minster for Public Transport and Roads) must approve all land deemed surplus and available for disposal.
The method of sale is then determined and consultant advice is sought:
(1) Planning.
(2) Valuer General Victoria (Valuer General’s office must provide a valuation for all sales).
(3) Government Land Monitor (Land Monitor approval is sought if the value exceeds $750,000).
(4) Environmental.
(5) Local Council." [www.vicroads.vic.gov.au/ planning-and-projects/ property-services/ property-management]
