Scholars in various disciplines who are concerned about the tendency toward the fragmentation of knowledge and the increasing complexity of phenomena have sought a unifying approach to knowledge. Luduring von Bertalanlfy, a biologist, developed a general systems thereby that applied to any arrangement of elements such as cells, people, societies or even planets. Norbert Wiener, a mathematician observed that information and communications provides connecting links for unifying fragments or elements, His systems concept of information theory, which shows the parallel between the functioning of human beings and electronic systems, laid the foundation for today’s computer systems. Herbert A. Simon, a political scientist, related the systems concept to the study of organizations by viewing an ongoing system as a processor of information for making decisions. Systems analysis and information systems were founded in general systems theory, which emphasizes a close look at all parts of a system. Too often analysts focus Continue reading

Limitations of Enterprise Resource Planning (ERP) Systems
In today’s increasingly competitive world where the world is converging into a single market place, organizations are looking for ways to become globally competitive. Companies must be able to meet customer requirements in the shortest possible time faster than competition and this requires extensive production planning and close coordination between the company and it’s suppliers and customers. MRP (Materials Requirement Planning) was one of the most widely used systems for production planning but it’s main focus was only on managing the production requirements in an organization. MRP systems helped in time phase release of production orders and aggregating planning for material requirements. With time, companies realized that there needed to be an integration of all the functions in an organization and this lead to the development of ERP (Enterprise resource planning) systems. ERP is defined as an Enterprise wide system that facilitates integrated and real-time planning, production and customer response. Continue reading

Generation of Computers
It is important to realize that major changes and trends in computer systems have occurred during the major stages-or generations-of computing, and will continue into the future. The first generation of computers developed in the early 1950s, the second generation blossomed during the late 1960s, the third generation took computing into the 1970s, and the fourth generation has been the computer technology of the 1980s and 1990s. A fifth generation of computers that accelerates the trends of the previous generations is expected to evolve as we enter the 21st century. Notice that computers continue to become smaller, faster, more reliable, less costly to purchase and maintain, and more interconnected within computer networks. First-generation computing involved massive computers using hundreds or thousands of vacuum tubes for their processing and memory circuitry. These large computers generated enormous amounts of heat; their vacuum tubes had to be replaced frequently. Thus, they had Continue reading
Areas of Data Processing
Data processing is the manipulation of data into a more useful form. It is the modern name for paperwork and involves the collecting, processing, and distributing of facts and figures to achieve a desired result. Data processing includes not only numerical calculations but also operations such as the classification of data and the transmission of data from one place to another. In general, we assume that these operations are performed by some type of machine or computer, although some of them could also be carried out manually. Data processing system refers to the equipment or devices and procedures by which the result is achieved. Read More: Concept of Data Processing Data processing may be classified as either scientific or business in nature. Business Data processing (BDP) . Business data processing is characterized by the need to establish, retain, and process files of data for producing useful information. Generally, it involves Continue reading
The Focus of Business Process Reengineering (BPR) on the Current Issues in Business
The existing system in the organization is totally reexamined and radically modified for incorporating the latest technology. This process of change for the betterment of the organization is called as Business process reengineering. With Business process being reengineered, the organizations have to change the workflow and business procedures for efficiency in the organization. Latest software are used and accordingly the business procedures are modified, so that documents are worked upon more easily and efficiently. This is called as workflow management. Business process reengineering is a major innovation changing the way organizations conduct their business. Such changes are often necessary for profitability or even survival. BPR is employed when major IT projects such as ERP are undertaken. Reengineering involves changes in structure, organizational culture and processes. Many concepts of BPR changes organizational structure. Team based organization, mass customization, empowerment and telecommuting are some of the examples. The support system in any Continue reading
