TYPES OF SYSTEMS

1. Transaction Processing Systems (TPS)

It is a computerized information systems that were developed to process large amounts of data for routine business transactions. TPS eliminates the tedium/tediousness of necessary operational transactions and reduces the time once required to perform them manually. TPS are boundary-spanning systems that permit the organization to interact with external environments. Because managers look to the data generated by the system for up-to-the-minute information about what is happening in their companies, it is essential to the day-to-day operations of the business that these systems function smoothly and without interruption.

2. Office Automation Systems and Knowledge Work Systems

At the knowledge level of the organization are two classes of systems: Office automation systems (OAS) support data workers, who do not usually create new knowledge but rather analyze information to transform data or manipulate it in some way before sharing it with, or formally disseminating it throughout, the organization, and, sometimes, beyond. Familiar aspects of OAS include word processing, spreadsheet, desktop publishing, electronic scheduling, and communication through voicemail, email (electronic mail), and teleconferencing. Office automation almost always implies a network of computers with a variety of available programs. (read more…)

3. Management Information Systems

management information system (MIS) is a computerized database of financial information organized and programmed in such a way that it produces regular reports on operations for every level of management in a company. It is usually also possible to obtain special reports from the system easily. (read more…)

4. Decision Support Systems

A decision support system (DSS) is a computer program application that analyzes business data and presents it so that users can make business decisions more easily. It is an “informational application” (to distinguish it from an “operational application” that collects the data in the course of normal business operation). (read more…)

5. Artificial Intelligence and Expert Systems

Artificial intelligence is the branch of computer science concerned with making computers behave like humans. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology. (read more…)

In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning about knowledge, represented primarily as if–then rules rather than through conventional procedural code. (read more…)

 

6. Group Decision Support Systems and Computer-Supported Collaborative Work Systems

Group decision support system (GDSS) technology supports project collaboration through the enhancement of digital communication with various tools and resources. These types of programs are used to support customized projects requiring group work, input to a group and various types of meeting protocols.  (read more…)

 

7. Executive Support System
