شبكه جهاني از سيستم اطلاعاتي به عنوان سيستمي ياد مي كند كه شامل شبكه همه كانالهاي اطلاعاتي مي باشد كه در داخل يك سازمان مورد استفاده قرار مي گيرد . همچنين مي توان سيستم اطلاعات مديريتي را به عنوان سيستمي تعريف كرد كه به جمع آوري و پردازش اطلاعات پرداخته و اين اطلاعات را در اختيار مديران قرار داده تا از آن در جهت تصميم گيري ، برنامه ريزي ، اجراي برنامه و نظارت استفاده نمايند . يك سيستم اطلاعاتي مشتمل بر همه بخشهايي است كه به گردآوري ، پردازش و اشاعه اطلاعات مي پردازند . معمولا اين سيستم شامل سخت افزار ، نرم افزار ، انسانها ، سيستم هاي ارتباطي مانند خطوط تلفن و اطلاعات مي باشند . فعاليت هايي كه در اين سيستم صورت مي گيرد عبارتند از وارد كردن داده ها ، پردازش داده به اطلاعات ، ذخيره سازي داده ها و اطلاعات و توليد خروجي هايي از قبيل گزارشات مديريتي .
از سيستم اطلاعات تحت عنوان مديريت تكنولوژي اطلاعات ياد مي شود .معمولا مطالعه سيستم هاي اطلاعاتي جزء رشته مديريت بازرگاني بوده و شامل برنامه ريزي و اجراي برنامه هاي نرم افزاري مي شود . بنابراين حوزه از مطالعات با دانش كامپيوتر يا مهندسي كامپيوتر اشتباه شود . دانش كامپيوتر از نظر ماهيت بيشتر نظري بوده و در رابط با توليد نرم افزار مي باشد و مهندسي كامپيوتر نيز بيشتر بر طراحي سخت افزار هاي كامپيوتري تمركز دارد .

Management information system
(MIS)
From Wikipedia, the free encyclopedia.
(Redirected from Management Information Systems)
Jump to: navigation, search
Management Information Systems (MIS) are information systems, typically computer-based, that are used within an organization. WordNet describes an information system as "a system consisting of the network of all communication channels used within an organization". A management information system may also be defined as "a system that collects and processes data (information) and provides it to managers at all levels who use it for decision making, planning, program implementation, and control." An information system is comprised of all the components that collect, manipulate, and disseminate data or information. It usually includes hardware, software, people, communications systems such as telephone lines, and the data itself. The activities involved include inputting data, processing of data into information, storage of data and information, and the production of outputs such as management reports.
As an area of study it is commonly referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with [Computer Science] which is more theoretical in nature and deals mainly with software creation, or [Computer Engineering], which focuses more on the design of computer hardware.
In business, information systems support business processes and operations, decision-making, and competitive strategies.

The functional support role
The business processes and operations support function is the most basic. It involves collecting, recording, storing, and basic processing of data. Information systems support business processes and operations by:
• recording and storing sales data, purchase data, investment data, payroll data and other accounting records
• processing these accounting records into income statements, balance sheets, ledgers, management reports, and other forms of financial information
• recording and storing inventory data, work in process data, equipment repair and maintenance data, supply chain data, and other production/operations records
