Enterprise computing refers to the use of computers and computer technology within business organizations. There are several types of enterprise information systems that are used in businesses, including executive support systems, decision support systems, management information systems, knowledge management systems, office automation systems, and transaction processing systems. Each type of system has a specific purpose, such as helping senior management make strategic decisions, processing routine transactions efficiently, or creating and sharing knowledge within an organization. While enterprise information systems can provide benefits like improved management and a unified platform, they also have disadvantages like being difficult and expensive to implement and requiring fundamental changes to business operations.

13. Major Types of Enterprise Information Systems Executive Support Systems (ESS) Decision Support Systems (DSS) Management Information Systems (MIS) Knowledge Management Systems (KMS) Office Automation Systems (OAS) Transaction Processing Systems (TPS)

14. Executive Support Systems An Executive Support System ("ESS") is designed to help senior management make strategic decisions. It gathers, analyses and summarises the key internal and external information used in the business.

15. Decision Support Systems Decision-support systems ("DSS") are specifically designed to help management make decisions in situations where there is uncertainty about the possible outcomes of those decisions. DSS comprise tools and techniques to help gather relevant information and analyse the options and alternatives. DSS often involves use of complex spreadsheet and databases to create "what-if" models.

16. Knowledge Management Systems Knowledge Management Systems ("KMS") exist to help businesses create and share knowledge information. These are typically used in a business where employees create new knowledge and expertise - which can then be shared by other people in the organisation to create further commercial opportunities. Good examples include firms of lawyers, accountants and management consultants.

17. Office Automation Systems Office Automation Systems (“OAS”) are systems that try to improve the productivity of employees who need to process data and information. Perhaps the best example is the wide range of software systems that exist to improve the productivity of employees working in an office (e.g. Microsoft Office XP) or systems that allow employees to work from home or whilst on the move.

18. Transaction Processing Systems As the name implies, Transaction Processing Systems ("TPS") are designed to process routine transactions efficiently and accurately.

19. Management Information Systems A management information system ("MIS") is mainly concerned with internal sources of information. MIS usually take data from the transaction processing systems and summarise it into a series of management reports.
