by Structure of MIS may be understood by looking at the physical components of the information system in an organization. The physical components of an organizational information system may be hardware, software, database, manual procedures and operating persons.
Input
Employees working with the fundamental information for your business such as orders received, sales, invoices and payments input the data into desktop computers. Marketing and production often add additional operating information through computers in their departments. The computers each link to routers and central servers via the special cables of an ethernet network. While wireless networks are more convenient because you don’t need cables, many companies prefer wired networks because of their higher level of security. When evaluating a management information system, make sure the input data include the information you need and that they are transmitted securely to the servers.
Software
Software is a broad term given to the instructions or programs that direct the operating of the hardware. Software could be of two types, i.e. system software and application software.
Hardware
Hardware refers to the physical data processing equipment and peripheral devices, For example, CPU, monitor, keyboard, printer, drives, tapes, communication devices, etc.
Procedures
A central server in your facilities handles processing. It runs the core program that calls up data from the database and performs the necessary calculations. When you want a report on sales and profit totals each year over the last five years, the raw data are in the database but the totals may not be. The server takes your request, finds the individual sales and profit figures, adds them and displays the results. If you now decide a percentage change for each year would be more useful, the server calculates that.
Formal operating procedures, which are required to operate a system, such as manuals, are also regarded as physical elements.
Database
The database consists of all data utilized by application software. Data is stored in files.
Operating Personnel
Personnel like Computer Operators, Computer Programmers, System Analysts, System Managers, etc., are the operating people of the information systems.
Input and Output Various physical inputs and outputs from the information system, existing in forms like printout, reports etc.
Output
The server processing your request completes the calculations and outputs the results through the ethernet network to your computer. As a first step, it usually displays the results on your screen. Often you can configure the output report to display the data in tables or graphs and request a format that lets you distribute a paper report or email a digital file. The server processes your request and provides you with the corresponding output file for printing out or emailing.
