Importance Of Management Information System Management information system is an integrated set of component or entities that interact to achieve a particulars function, objective or goal. Therefore it is a computer based system that provides information for decisions making on planning, organizing and controlling the operation of the sub-system of the firm and provides a synergistic organization in the process. The component of an information system includes. a hardware which is used for input/output process and storage of data, software used to process data and also to instruct the hand-ware component, data bases which is the location in the system where all the organization data will be automated and procedures which is a set of documents that explain the structure of that management information system. There are various driving factors of management information system for example:- Technological revolutions in all sectors make modern managers to need to have access to large a

MIS functions to produce routine reports,DSS employ sophisticated data modelling & analysis tools for the purpose of resolving structured problems. MIS is used by a limited group (staff managers & professionals), DSS are used by groups,individuals & managers at various levels. DSS is charachterized by an adaptability which contrasted with the semi-inflexible nature of MIS. DSS data sources are much more varied comprising inventory, accounting & production sources & not just internal business ones & its analytical tools are more sophisticated(simulation,atatistical analysis). Thus, MIS & DSS are differentiated in terms of components, dynamics , analytical tools & general properties.

NEED FOR SYSTEMS ANALYSIS AND DESIGN Systems analysis and design, as performed by systems analysts, seeks to understand what humans need to analyze data input or data flow systematically, process or transform data, store data, and output information in the context of a particular business. Furthermore, systems analysis and design is used to analyze, design, and implement improvements in the support of users and the functioning of businesses that can be accomplished through the use of computerized information systems. Installing a system without proper planning leads to great user dissatisfaction and frequently causes the system to fall into disuse. Systems analysis and design lends structure to the analysis and design of information systems, a costly endeavor that might otherwise have been done in a haphazard way. It can be thought of as a series of processes systematically undertaken to improve a business through the use of computerized information systems. Systems analysi

Use of Information Management Systems The management of Information is facilitated by the use of Information Technology and Information Sciences. The popular Information Management Systems can be listed as follows: Document management system (DMS) The DMS is focused primarily on the storage and retrieval of self-contained electronic data resources in the document form. Generally, The DMS is designed to help the organizations to manage the creation and flow of documents through the provision of a centralized repository. The workflow of the DMS encapsulates business rules and metadata. Content management system (CMS) The CMS assist in the creation, distribution, publishing, and management of the enterprise information. These systems are generally applicable on the online content which is dynamically managed as a website on the internet or intranet. The CMS system can also be called as ‘web content management’ (WCM). Library management system (LMS) Library management systems facilitate

Systems Analysis Systems analysis includes a review of the present information system to assess its capabilities and shortcomings; specification of system goals, objectives, and constraints; a survey of potential system users to assess their information needs; identification and analysis of alternative system concepts; specification a system concept; and system requirements analysis and specification.This phase includes an analysis of major system functions and the development of a system architecture (identification of the major system components and their interrelationships). Heavy emphasis is placed on end-user requirements. It is essential to involve the end-user in the system requirements activity, to insure the development of a system that is fully responsive the user's needs. The review of the current system and survey of potential users can be done by a variety of means, including review of documentation, site visits, questionnaire surveys, interviews, and focus-group discu

CONCEPT OF DBMS A Database Management System ( DBMS ) is a set of computer programs that controls the creation, maintenance, and the use of the database with computer as a platform or of an organization and its end users . It allows organizations to place control of organization-wide database development in the hands of database administrators (DBAs) and other specialists. A DBMS is a system software package that helps the use of integrated collection of data records and files known as databases. It allows different user application programs to easily access the same database. DBMSs may use any of a variety of database models , such as the network model or relational model . In large systems, a DBMS allows users and other software to store and retrieve data in a structured way. Instead of having to write computer programs to extract information, user can ask simple questions in a query language . Thus, many DBMS packages provide Fourth-generation programming language (4GLs) and

Basic concepts Data versus Information Data refers to raw, unevaluated facts, figures, symbols, objects, events, etc. Data may be a collection of facts lying in storage, like a telephone directory or census records. Information is data that have been put into a meaningful and useful context and communicated to a recipient who uses it to make decisions. Information involves the communication and reception of intelligence or knowledge. It appraises and notifies, surprises and stimulates, reduces uncertainty, reveals additional alternatives or helps eliminate irrelevant or poor ones, and influences individuals and stimulates them to action. An element of data may constitute information in a specific context; for example, when you want to contact your friend, his or her telephone number is a piece of information; otherwise, it is just one element of data in the telephone directory. Computers have made the processing function much easier. Large quantities of data can be processed quickly

A Decision Support System (DSS) is a class of information systems (including but not limited to computerized systems) that support business and organizational decision-making activities. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from a combination of raw data, documents, personal knowledge, or business models to identify and solve problems and make decisions. Typical information that a decision support application might gather and present are: an inventory of all of your current information assets (including legacy and relational data sources, cubes, data warehouses, and data marts), comparative sales figures between one week and the next, projected revenue figures based on new product sales assumptions. Development Frameworks DSS systems are not entirely different from other systems and require a structured approach. Such a framework includes people, technology, and the development approach. [ 10 ]

Decision making can be regarded as an outcome of mental processes (cognitive process) leading to the selection of a course of action among several alternatives. Every decision making process produces a final choice. The output can be an action or an opinion of choice. Decision making is a reasoning or emotional process which can be rational or irrational, can be based on explicit assumptions or tacit assumptions.Thus here an important concept comes of RATIONAL DECISION MAKING Rational Decision Making A rational decision is the one which, effectively and efficiently, ensures the achievement of the goal for which the decision is made. In reality, there is no right or wrong decision but a rational or an irrational decision. The quality of decision making is to be judged on the rationality and not necessarily on the result it produces. The rationality of the decision made is not the same in every situation. It will vary with the organization, the situation and the individual’s view of
