Definition of Management Information Systems
Definition of Management Information Systems (MIS)In the sense that it should, Management information systems (MIS) is an achievable goal, a clear long-term plan, which is key to achieving the target, is possible only if there is no appreciation for the various dimensions of the concept of Management Information Systems.Actually there are several dimensions MIS so there is no simple difenisi able to describe the sense of menyeluruh.Untuk it takes an understanding of the background in the science system so makana "Management Information System" or MIS Dapa dipahmi completely.Management information system (MIS) is a series of sub-sisitem thorough information in a rational and coordinated and integrated so that the data mentranspormasi be able to get through a series of ways to improve productivity in accordance denagan style and nature of the basic criteria of the quality manager who has ditetapkan.Untuk clarify the more detailed what information sisitem sebenarnaya tu Management (MIS) with latara explain a little behind on pembhasan paper will clarify thisUNDERSTANDING MANAGEMENT INFORMATION SYSTEMA. UNDERSTANDING SIMA management information system, or SIM, is an information system in addition to all transaction processing is necessary for an organization, also provides support for the processing of information and management functions and decision making. The idea of such an information system that existed before the advent of computers. But the computer to make that idea a reality. Organization always requires systems to collect, process, store, looking back, and distribute information. Computers have added a new and powerful technology in information systems. As a result, a computer-based information system will really different from the systems that processed manually or electro-mechanical. Siatem management information is described as a pyramid building, diimana layer consists essentially of information for transaction processing, annotation status, etc., the next layer consists of sources of information in support of daily operations management; third layer consists of resource information system for assist planning and tactical decision making for management control, and the top layer consists of information resources to support planning and policy formulation by top level management.Driver's licensetoplanstrategic andDecision-makingInformation management for the peTactical planning and decision-DecisionManagement information for planningoperations, decision making and controlTransaction processing, information (feedback) onquestionMany scholars define management experts Information Management System, for example, Gordon B. Davis, Joel E. Ross, Donald W. Lroeber, and much more.The definition of the Donald W. Kroeber in his book Management Information Systems said that the Management Information System is an organization, a process that provides information to managers as a support in the operation and decision making within an organization.Gordon B. Davis said that the Management Information System is an integrated system users yangn menyediakaninformasi to support operations management and decision-making functions in an organization. The system utilizes hardware and computer software and manual procedures; models for analysis, planning, supervision and decision-making and a data base.SIM in terms of previous scholars opinion:A. Emphasized in an engine system.2. An organization.3. Party information providers.4. Contained within an organization.5. Intended for something that is a company's operations, analysis and decision making.6. Computers are involved, the procedure, a data base.Now we see how Joel E. Ross believes the same thing. Despite the fact that the computer is nothing more than tools to process data, many managers view the computer as a central element of an information system. The tendency of this attitude is too high and distorting the role of the computer. Actual role of computers is to provide information for decision-making, planning and control. Real emphasis on business information systems business is too much when the magazine ran an article today is not about information systems, data collection, basic relationships. Many businesses have managed to combine management, information system and show its relationship with the computer.Definition of a Management Information System, commonly known as the term, is a sstem human / machine unified (integrated), to provide information to support the functions of the operation, management, and decision making within an organization. The system uses hardware (hardware) and software (software) computers, procedures guidelines, models and management decisions, and a 'data base'.A. Human Systems / Computer Based EngineeringInteraction of human / machine is enriched through the operation of 'on-line' where the terminal input / output (input / output} is connected to the computer to provide direct input and output gain on the application of the beneficiaries of such circumstances. Operations 'on-line' is necessary for dialogue human / machine, but there are many tasks that clerks processing more efficient without the input / output termanual.2. Integrated with a Data Base SystemAn integrated system based on the assumption that there must be integration between data and processing. Intergasi data is achieved through a "data base". On an information processing system, "data base" consists of all data that can be reached by the system. SIM is based on a computer, the term "data base" is usually used for data that can be reached directly by the computer. Management of a "data base" is a computer software system known as a data base management system.3. Utilization Management and Decision ModelIt is not enough for someone when only accepts raw data or even just an overview of the data. There should be a way to process and present data in such a way that the results lead to the decision to be taken. The result should encourage the decision. Methods for doing this is to process the data in the form of a decision model. Example, an investment decision than the new capital expenditure must be processed in the form of a capital expenditure models that influenced the rate of profit based on the constraints with respect to the size and risks.
