DSS Software
INTRODUCTION Introduction to DSS (Decision Support System) Software What is DSS Software? Decision Support System Software (DSS Software) is an interactive computer-based system intended to help managers make their decisions. It is an application software that provides several ways to support decision making and modelling information in such way to be better arranged for user. Why DSS Software was built? DSS Software was built because of the explosion of e-commerce activity, and people face more complex problem in making decision, especially business decisions, which have high risk of assets. What can DSS Software do? DSS Software can support several management decision-making and decision type at all level. ... How is DSS Software useful? DSS Software helps people to retrieve, summarize and analyse decision relevant data. ... What are the two major categories of DSS Software? There are actually two major categories of DSS Enterprise-Wide DSS and Desk-top DSS. Enterprise-Wide DSS are linked to large, data warehouse and serve many users in a company, while Desk-top DSS are small system that is in a PC. What are the advantages of using the two major types of DSS Software? Enterprise-Wide DSS Why people use Enterprise-Wide DSS is because users (manager usually) can find out almost anything about their company matter in moments rather than using some data warehouse like OLAP type system. Enterprise-Wide DSS can cover from simple system to complex data intensive and analytically of information system. The most sophisticated Enterprise-Wide DSS is EIS (Executive Information System) because it uses good graphics, data storage method and also easy on line access to current information about a matter. Because of its wide scope and high development cost Enterprise-Wide DSS is used. Desk-top DSS Why people use Desk-top DSS is because sometimes Desk-top DSS is especially useful means that sometimes people can use Excel or Lotus 123 for single analyses. But when actually Desk-top DSS can do what Excel or other type of software can do such as: „« Structuring of complex problems „« Developing priorities and ranking alternatives „« Measuring consistency of judgments „« Allocating resources and conducting a cost/benefit analysis For more to know what is the useful of DSS visit this URL http://www. ... com And for current situation actually Database of DSS is implemented in Microsoft Access. ... What are the disadvantages of DSS Software? ... ¡¨ The above phrase explains the major drawback of DSS Software. The decision suggested best by the DSS Software need not be the best decision as there are other unexpected events that can occur. ... What are the current DSS Software applications? DSS is a software that is software runs on a PC not On line Transaction Processing System (OLTP) and helps someone to make decision for current type of DSS are DSS itself, (Executive Information System) EIS, ESS, Geographic Information System (GIS),and OLAP These are few examples of the uses of DSS: ƒæ A manager wants to know total sales for each of the last five years ƒæ What items have been out of stock more than 5 days in a month? ƒæ Which customers had the most orders ($value) in a year ƒæ Searching whether profit target is achieved ƒæ Searching whether salespersons have achieved their sales goals What are the future developments of DSS Software? Artificial Intelligence (AI) is best tried to be used in DSS Software since AI can quickly solve fuzzy logic. ... Some of the DSS Softwares are also being developed on line, meaning the DSS can support user, who faces very complex problem, and provide interactive analyze relationship, that relates large data stored in multidimensional databases. This can also be called as data mining using DSS software and internet. Some people think that a "new type" of DSS Software which is called OLAP (On Line Analytical Processing) would replace the DSS Software.
