In addition, they write programs to codify that technology and later manage it. As such, the IS professional might develop code for business transaction processing systems, client/server systems or end-user support systems; they might implement such systems in languages as COBOL, C++, Visual Basic or JAVA (Oldbach, 1995). IS specialists also design and administer databases and data warehouses, analyse and implement enterprise-wide solutions to information problems and manage telecommunications efforts. Some IS specialists implement and manage corporate-wide Intranets. Finally, IS specialists can also provide project management skills, technical writing or training by melding their knowledge of information technology and business processes.
Management information system (MIS) is a computer-based system that makes information available to users with similar needs. The users usually compose a formal organisational entity-the firm or a subsidiary sub-unit. The information describes the firm or one of its major systems in terms of what has happened in the past, what is happening now, and what is likely to happen in the future. The information is made available in the form of periodic reports, special reports, and outputs of mathematical simulations. Both managers and non-managers use the information output as they make decisions to solve the firm's problems (deForte & Jones, 1994).
The database contains the data provided by the AIS. In addition both data and information are entered from the environment. Software that produces periodic and special reports, as well as mathematical models that simulate various aspects of the firm's operations uses the database contents. Persons who are responsible for solving the firm's problems use the software outputs. Some of the problem solvers can exist within the firm's environment. The environment becomes involved when the firm brands together with such other organisations as suppliers to form an inter-organisational information system (IOS). In that case, the MIS supplies information to the other members of the IOS.
As firms gained experience in implementing company-wide MIS designs, managers in certain areas began applying the concept to their own needs. These functional information systems, or subsets of the MIS that are tailored to meet users' needs for information concerning functional areas, received much publicity in some areas and somewhat less in other.
The system required in school for the teachers and students in the school is a simple one. It will just require the solution database, SQL server that is a part of windows server system will hold the information about the school. SQL server offers rich data analysis and data mining capabilities that integrate with familiar applications such as Microsoft Office (Cadle & Yeates, 2001).
SQL server will be hosted centrally on a cluster of hardware devices, enabling the addition of new servers to the cluster on an incremental basis. This makes solution highly reliable and able to scale to accommodate future expansion.
