Decision guide structures usually contain non-programmed choices. Therefore, there can be no precise record, content, or layout for those structures. Reports are generated at the fly.
Attributes of a DSS
• Adaptability and flexibility
• High degree of Interactivity
• Ease of use
• Efficiency and effectiveness
• Complete manipulate through selection-makers
• Ease of development
• Extendibility
• Support for modeling and evaluation

• Support for intelligence, design, choice, and implementation.
• Support for style of selection approaches and styles.
• DSSs are adaptive over time.
Benefits of DSS
• Improves performa
nce and pace of selection-making activities.
• Increases the manipulate, competitiveness and functionality of futuristic selection-making of the enterprise.
• Facilitates interpersonal communication.

• Since it's miles normally utilized in non-programmed choices, it well-knownshows new strategies and units up new evidences for an uncommon selection.
• Helps automate managerial approaches.
Components of a DSS
Following are the additives of the Decision Support System
Database Management System (DBMS) − To clear up a hassle the vital facts might also additionally come from inner or outside database. In an enterprise, inner facts are generated through a gadget consisting of TPS and MIS. External facts come from a lot of reassets consisting of newspapers, on-line facts services, databases (economic, marketing, human resources).
Model Management System − It shops and accesses fashions that managers use to make choices. Such fashions are used for designing production facility, reading the economic fitness of an enterprise, forecasting call for of a product or service, etc.
Support Tools − Support equipment like on-line assist; pulls down menus, person interfaces, graphical evaluation, mistakess correction mechanism, enables the person interactions with the gadget.
Classification of DSS
There are numerous approaches to categorise DSS. Hoi Apple and Whinstone classifies DSS as follows
Text Oriented DSS − It incorporates textually represented facts that would have a pertaining to selection. It permits files to be electronically created, revised and considered as needed.
Database Oriented DSS − Database performs a first-rate function here; it incorporates prepared and relatively established facts.
Spreadsheet Oriented DSS − It incorporates facts in unfold sheets that permits create, view, adjust procedural understanding and additionally instructs the gadget to execute self-contained instructions. The maximum famous device is Excel and Lotus 1-2-3.
Solver Oriented DSS − It is primarily based totally on a solver, that's an set of rules or method written for appearing positive calculations and unique application type.
Rules Oriented DSS − It follows positive processes followed as guidelines.
Rules Oriented DSS − Procedures are followed in guidelines orientated DSS. Export gadget is the example.
Compound DSS − It is constructed through the use of or extra of the 5 systems defined above.
Types of DSS

Accounting System − It maintains music of accounting and finance associated facts, for instance, very last account, bills receivables, bills payables, etc. that preserve music of the fundamental elements of the commercial enterprise.
