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]

This example of automated payroll management system UML activity diagram was created on the base of figure on the webpage "Automated payroll management system" from ethelmandane.wikispaces.com.
"In the Philippines and in other foreign countries the government has a trend to embrace automation for process efficiency. One of the processes that are being automated is the payroll process. Payroll is the total amount required to pay workers and employees during a week, month or other period.
One of the government offices that desires to automate their payroll system is the NSO Camarines Sur which is located 2nd Floor MMCN Building, Panganiban Avenue, Naga City. The National Statistics Office (NSO) envisions to be recognized as a world-class provider of statistical and civil registration products and services and lives with its mission to produces and provides quality statistical and civil registration products and services. ...

"Microsoft SharePoint is a Web application platform developed by Microsoft. First launched in 2001, SharePoint has historically been associated with intranet, content management and document management, but recent versions have significantly broader capabilities.
SharePoint comprises a multipurpose set of Web technologies backed by a common technical infrastructure. By default, SharePoint has a Microsoft Office-like interface, and it is closely integrated with the Office suite. The web tools are designed to be usable by non-technical users. SharePoint can be used to provide intranet portals, document & file management, collaboration, social networks, extranets, websites, enterprise search, and business intelligence. It also has system integration, process integration, and workflow automation capabilities.
Enterprise application software (e.g. ERP or CRM packages) often provide some SharePoint integration capability, and SharePoint also incorporates a complete development stack based on web technologies and standards-based APIs. As an application platform, SharePoint provides central management, governance, and security controls for implementation of these requirements. The SharePoint platform integrates directly into IIS - enabling bulk management, scaling, and provisioning of servers, as is often required by large organizations or cloud hosting providers."
