IntroductionThe paper describes information technology software’s that are used by the firms in their department. This software’s remain an important area as they enhance the communication system, within the departments and with their customers. This software’s, their implementation is described with their benefits. Later the section describes the social impact of information technology on the firm and on the society. Before describing the information technology software, let defines in simple words that what information technology software is. Information technology software gather, store, process and pass the data to all levels in the hierarchy.
ISDMThe data processing system mainly depend on the condition of the firm, its hierarchy and size. The activities involved in data processing within the department lines are as Store Management, Production planning and control, financial accounting management and so forth. with the growth in the technology the concept of integrated data processing also changes. Mainly the ISDM is divided into two main broad categories and these are given as follows. Centralized Data Processing SystemDue to increase use of computers in the firm, there is a growing tendency of management to sue the centralized data processing system.
In centralized data processing system, a separate department Electronic Data Processing (EDP) is established which mainly deal with the data processing work within different departments of the firm. Some time the firm hire the activities of other firm for data processing activities. The benefits of data centralized system is given asThe data emerge only at one placeThe risk of loss of data is minimized by this methodThe methods and machines used can be standardizedThe process is very cost-effectiveThe work duplication is avoided by this process.
Decentralized data Processing systemIn decentralized data processing system, the computing services are broken into different departments of the firm. Each department handles its own computing system without interacting with other departments. This type of system is suitable with the firm that is holding decentralization system in it. For instance, usually the research system or department of huge system adopt the process of decentralization data processing system. Information SystemInformation system for the organization is required as Management wants to know the process and activities of its departments. This helps the Management to develop better Information technology software for the firm.
The information system is broken across different departments that help in getting the whole information of the departments. Due to information system the whole firm is view as network of inters related sub-system rather the hierarchy system of the firm. Under ISDM different methods are taken in account but not all the methods can be used by the manager and owner of the firm as some of these are only used in the complex organization hierarchyDSDM (Dynamic systems development method)This application is based on RAD (rapid application development) and required continuous user involvement, furthermore, it requires interactive development and incremental approach and these together helps to response the changing requirements.
These all together helps in making new software system that used to satisfy the business requirements. It consist of three phases
