The focus is on a peripheral issue: thechoice between distributed computer hardware and central computer hardware. It Is more useful to focus on a very different issue: the difference between organizational computing and personal computing inorganizational information systems. The primary problem is that of control; how can centralized information processing organizations ensure that the correct data is used, that it is protected, that the systems developed are what end users need, and that such development represents productive use of computing resources without getting in the way of productive use of computing resources to solve individuals resource problems? .
The proper role of personal computers in organizations is one of the most commonly discussed problems in MIS (Management Information System) today. The primary problem is that of control; how can personal computer users be made subject to controls on the information system, and how can centralized information processing organizations ensure that the correct data is used, that it is protected. Organizational computing refers to the use of computing resources to create systems which are used as utilities or information infrastructures by several members of an organization .
There are two differences which distinguish organizational computing from personal computing. The first is impact on others within the organization (direct with organizational computing; indirect with personalcomputing). The second is method of control (through system integration with organizational computing:through the management control system with personal computing).This paper discusses the differences between organizational computing and personal computing, the similarities and differences between their requirements, their relative suitability for end user developed systems, technical and other issues in their support, and the connections between the organizational and the personal computing systems within organizations.
Organizational computing: Organizational computing is the creation of information utilities or infrastructures to support the formal information system within the organization. Traditional system design techniques attempt to determine what computer systems will best serve the needs of the organization as a whole, and how these systems can be fitted together into an integrated organizational information system.
The most basic example of organizational information systems is an accounting system.
Requirement for organizational computing:
The key requirement for organizational information systems is that they be usable by any authorized user who needs to use them. Hence the traditional emphasis on centralized systems; not so much because of the increased efficiencies which arise from Grosch's law, but rather from the need for files and other resources to be accessible to many different users within the organization.
Control of Organizational Computing:
Control of organizational computing is divided into system planning and system operation. Nolan's stages hypothesis  emphasizes the importance of both types of control for mature information systems.
Which limit access? These standards could include, for example, the use of accounts and passwords to restrict use of the system, limitations on access to files, the inability to write or replace files which one is allowed to read, limitations on who can change what program, and controls on terminal access.
Review: here in the above journal in which how the centralized control management systemis managed by taking the companys accounting system where accessing system arise within the users in the organization.here the traditional system design techniques are determined by taking the example of organizational computing.Its similar to my project but here they are using the traditional design techniques where here the peripherals in company are using java and implementing the mail service to server.
