TPS will update any transaction process and store that information in a database, so any concerned party in the organization can access that information via a centralized information storage network of internet.
Decision Support: A decision support system (DSS) is a highly flexible and interactive IT system that is designed to support decision making when the problem is not structured. A DSS works together with an artificial intelligence system to help the worker create information through (OLAP) online analytical process to facilitate decision making tasks that require significant effort and analysis.
Workgroup Support: Since information technology facilitates in the creating an information sharing environment, workers can easily consult each other across different department without any interruption. They can use emails, text chatting services to inquire some thing related to a given task at work. With work group support systems, group decision making becomes easier.
Executive Support: An executive information system (EIS) is an interactive management information system (MIS) combined with decision support systems and artificial intelligence for helping managers identify and address problems and opportunities. An EIS allows managers to view information from different angles. Yet it also provides managers with the flexibility to easily create more views to better understand the problem or opportunity at hand.
Data Management: With the help of database software, an organization stores all its relevant data on a database. This infrastructure can be designed when it is internal or external. An internal centralized system can only be accessed with in the organization while an external centralized system allows data to be accessed out side the organization using a remote (IP) internet protocol Address or a domain name. In this case, employees or managers can use a company website to access relevant company data by use of passwords. This data is not exposed to the public and search engines.
