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]

Network Layout
The Network Layout Diagram visually illustrates the arrangement of computers, nodes and other network appliances, such as servers, printers, routers, switches, hubs, and their relationships between each other. The network layout and placement of servers greatly influence on the network security and network performance. Elaboration of robust Network Layout Diagram is especially important when visualizing already existing network in order to understand its complexity; when troubleshooting the network issues; designing, documenting and implementing new network configurations; extending, modifying, or moving an existing network to other location. Through the careful thinking the network plan and designing the clear Network Layout Diagram, you can be confident in result on the stage of network implementation and to solve faster the problems appearing in network infrastructure. ConceptDraw DIAGRAM enhanced with Computer Network Diagrams solution from Computer and Networks area perfectly suits for drawing Network Layout Diagrams for different network topologies.
