2. Definitions of : DSS
According to Gerrity : DSS as an effective
blend of human intelligence , information
technology , and software which interact closely
to solve complex problems.
DSS is an interactive computer based system
which facilitates the solution of unstructured
problems.

3. DSS Characteristics-
Initial risk analysis (management science).
Model examination using experience, judgment, and
intuition.
Initial model mathematically correct, but incomplete.
DSS provided very quick analysis.
DSS: flexible and responsive. Allows managerial
intuition and judgment.
Facilities communication.
Consistent and objective decisions.

4. Objective of DSSIdentify information processing as the foundation
of managerial work.
Identify which media are more suitable for
supporting managerial work
Describe decision making/problem solving
systems in Organizations
Decision support content of different types of
information systems.
Differences in characteristics of Information
Systems.
Discuss models of decision making.
Describe decision making process.

5. Elements of DSSDSS tools.
 DSS tools are pograms or codes which are foundations
used to create the DSS generators and in turn specific
DSS.
DSS generators.
 The combination of DSS tools in the computer
hardware is know as DSS generators.
Specific DSS.
 DSS generators turn into specific DSS.

6. Components of DSS programsDialogue management.
Model management.
Database management.
Users of DSSThe use of DSS is not limited to middle and upper
level management or chief executives. They are the
main user. They bring with them differing
needs, and differing levels of sophistication. The
DSS designer need to specific decision–making
attributes in to consideration so that it is possible
for the user to interact successfully with the DSS.

7. Capabilities of DSS Can update or manipulate the database and select
data from database.
Create special reports in a desired format.
Perform calculations and execute aggregation of
data.
Produce report, memos, letters, and resume from
information available in the database.
Perform financial analysis.

8. Limitations of DSSDue to its small memories and limited storage
capacities, DSS has definite computational
constraints.
It is slow, compared to the speed of large
mainframes.
Most DSS are designed for individual but they
can be designed so that several computers can be
liked for limited information sharing.
