A Decision Support System is a computer-based information system that assists business or organizational decision-making activities. DSSs serve the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance.
An example of a decision support system is a software program that helps customer service representatives offer their company's products to customer. When the offer has been given, representatives can check off the product and the product will not appear as an available offer for the customer anymore.
A group decision support system (GDSS) refers to a collection of hardware, software, and procedures developed for the automated support of group work. It is also called an Electronic Meeting System.
Basically it is an Management of Information System. Here decision takers are contacted to find out what are the type of decisions usually taken by them. The system is successful as much the variety of decision taken is revealed. Then information required for the decision is derived on the basis of the practice followed the decision maker, his logic, he rules and reliance on the information. After Having the data requirements finalised, logics of decision finalised, suitable database system is installed and application programs are developed to provide the decision maker the information, and options availabe from the database for various decisions he takes on his desktop. Data warehousing is a well known decision support system. it is also stated as a move from intuitive decision to informed decision.
Decision support systems help people to be more consistent with their decision making. People are naturally subjective and may change their decisions based on all kinds of irrelevant criteria such as their personal mood the people affected by the decision etc.
These systems help to implement a formal method (such as a balanced score card) to take input data and produce a consistent and impartial decision that stands up to scrutiny.
Finally where it is impractical for a human to process all of the input data a decision support system can analyse the data and produce summary data and provide recommendations. However, ultimately the person can choose to override the computer's analysis - otherwise the system would be entirely automated.
There are a number of Decision Support Systems. These can be categorized into five types:
A decision support system is an intelligent system that helps managers make decisions. It uses ccccstored within the system along with parameters established by management.
a gdss is stands for group decision support system that helps in decision making to group of people.....:))

Decision support systems help managers analyze information within the organization. Based on this information, managers can make better decisions about pricing and profitability.
Decision support systems (DSS) contain decision-modeling routines, such as what-if analysis, whereby users can try particular decisions in simulations before actual implementation.
DSS
A management information system is a system that has important tools to supports, analyse, delivery and adding reliability to any organisation. Also this helps to solve businesses problems. The term MIS is often used to submit to a group of information management methods tied to the support of human decision making, e.g. Decision Support Systems, Expert systems, and Executive information systems.
There are three of these systems. They include transaction processing systems, operations information systems, and decision support systems or DSS.
Decision Support Systems as Information Systems
There are about four types of information systems that exist in the marketplace. They include management information, transaction processing, office information and decision support systems.

Marketing decision support systems can analyze customer buying preferences and determine target markets. Marketing decision support systems generally work across departments to get information about customers.

Support classification information systems are transaction processing systems, management information systems, knowledge management systems, office automation systems, decision support systems, group support systems.
Decision-making software is used to help people like business managers make decisions. Decision-making software analyzes data and tells us what the result of an action would be. We can use this information to make a good decision. Some types of decision-making software even help us by making decisions after analyzing data. Decision Support Systems (DSSs) and Expert Systems (ESs) are two types of decision-making

Decision support systems suited for executive decision-making as they are designed to analyze all aspects of data provided. This will help in making key managerial decisions.
