2.  Definition
 Introduction
 Functional Parts
 People Role
 Information Flow
 Finding
 Summary
 Conclusions

3.  A set of related computer programs and
the data required to assist with analysis and
decision-making within an organization.
E.g.
Bank loan verification.
Clinical decision support system.
Geographic information systems
(GIS).

4.  Inputs: Factors, numbers, and
characteristics to analyze.
 Processing: Result is generate by the DSS
based on users criteria.
 Outputs: Transformed data from which DSS
"decisions" are generated.
 Technology used: American Airlines
produced a DSS technology that helps to
decide and how to set prices for each seat
so that a plane is filled and profits are
maximized.

5. Decision support systems (DSS) are a subset of
computer-based information systems (CBIS). The
general term computer-based information
systems' is a constellation of a variety of
information systems such as office automation
systems, transaction processing
systems, management information systems and
management support systems. It was argued that
information systems should exist only to support
decisions, and that the focus of the information
systems development efforts should be shifted
away from structured operational control to
unstructured critical decisions in organizations.

6.  Programmers:
Who develop software/program.
 System analysis:
Translate business problems into
I.T solutions.
 I.S managers:
Department leaders.
 End users:
Customers for whom software is
developed.

8. DSS Open or close system?
 It may be open or close system
according to instructions given by the
programmer.
 Open system:
 When it is connected with other sub
systems like eBay, online ticketing etc.
 Closed system:
 When it is not connected with any other sub
system like Bank loan verification, Result making
system of university, college or school etc.

9. DSS preform following features:
 Improves personal efficiency.
 Speed up the process of decision making.
 Increases organizational control.
 Speeds up problem solving in an organization.
 Facilitates interpersonal communication.
 Promotes learning or training.
 Generates new evidence in support of a decision.
 Creates a competitive advantage over
competition.
 Create Innovative ideas to speed up the
performance.
 Helps automate managerial processes.

10. Decision support systems are powerful tools
integrating scientific methods for supporting
complex decisions with techniques developed
in information science, and are gaining an
increased popularity in many domains. They
are especially valuable in situations in which
the amount of available information is
prohibitive for the intuition of an unaided
human decision maker and in which precision
and optimality are of importance. Decision
support systems aid human cognitive
deficiencies by integrating various sources of
information, providing intelligent access to
relevant knowledge, aiding the process of
structuring, and optimizing decisions.

11.  The DSS have a bright future in industry,
Business as well as common life like
university, college and school
management systems.
 By the help of DSS we can solve big
problems in very short interval of time.
 DSS made the human life easy and
comfortable.
 It has a unique ability to detect and
solve the problem itself.
