DIFFERENCE BETWEEN DSS, EIS AND MIS

With the exposure to all or any the on top of data systems, allow us to decide the variations between DSS and MIS. Table-1 enlists some basic variations between call network,Management systems and govt data System. because the name implies, the later 2 area unit the systems that offer data which will or might not be used for creating a call whereas the support data provided for selecting the policy, designing or implementation is that the basic element of DSS.
Let us decide the characteristics of the 3 systems :
DSS:
– DSS typically offer support for unstructured, or semi-structured choices (decisions that can't be delineated  in detail).
– DSS issues area unit usually characterised by incomplete or unsure information, or the utilization of qualitative knowledge.
– DSS can usually embrace modelling tools in them, wherever numerous various eventualities are often sculpturesque and compared.
– Investment choices area unit associate samples of people who can be supported by DSS
MIS:
 MIS is mostly additional subtle coverage systems engineered on existing dealing process systems
 Often wont to support structured higher cognitive process (decisions that may be delineated  thoroughly before the choice is made)
 Typically also will support military science level management, however generally area unit used at alternative levels
 Examples of structured choices supported by MIS may embrace selecting stock levels or the evaluation of product

Dimension	DSS	MIS	EIS
Focus	Analysis, decision Support	Information processing	Status Access
Typical UsersServed	Analysts, professions,managers (via intermediaries)	Middle, lower levels, sometime senior executives	Senior Executives Expediency
Impetus	Effectiveness	Efficiency
Application	Diversified Areas where Managerial Decisions are made	Production control, sales forecasts, financial analysis,human resource management	Environmental scanning, performanceevaluation, identifying problems and opportunities
Database(s)	Special	Corporate	Special
Decision Support Capabilities	Supports semi-structured andunstructured decision making; mainly ad-hoc, but sometimes repetitive decisions	Direct or indirect support, mainlystructured routine problems, using standard operations, research and other models	Indirect support, mainly high level and unstructured decisions and policies
Type of Information	Information to support specific situations	Scheduled and demand reports; structured flow, exception reporting mainly internal operations	News items, external information on customers, competitors and the environment
Principal Use	Planning, Organizing, staffing and control	Control	Tracking and control
Adaptability to Individual User	Permits individual judgment, what-if capabilities, some choice of dialogue style	Usually none, standardized	Tailored to the decision making style of each individual executive, offers several options of outputs
Graphics	Integrated part of many DSS	Desirable	A must
User Friendliness	A must where no inter mediaries are used	Desirable	A must
Treatment of Information	Information provided by the EIS/or MIS is used as an input to the DSS	Information is provided to adiversified group of users who then manipulate it or summarize it as needed	Filters and compresses the information, tracks critical data and information
Supporting Detailed Information	Can be programmed into DSS	Inflexibility of reports, cannot get the supporting details quickly	Instant access to the supporting details of any summary
Model Base	The Core of the DSS	Standard Models are available but are not managed	Can be added, usually not included or limited in nature
Construction	By users, either alone or with specialists from IS or IC departments	By vendors or IS specialists	By Vendors or IS Specialists
Hardware	Mainframes, micros or distributed	Mainframes, Micros or distributed	Distributed system
Nature of Computing Packages	Large computational capabilities, modelling languages and simulation, applications and DSS generators	Application oriented, performance reports, strong reporting capabilities, standard statistical, financial, accounting and management science models	Interactive, easy to access multiple databases, on-line access, sophisticated DBMS capabilities and complex linkages
