ENTERPRISE INFORMATION INFRASTRUCTURE DESIGN AND CONCEPTS FOR ORGANIZATIONS

By Ritesh Srivastava Faculty IT, ICFAI National College Gorakhpur ABSTRACT In recent years there has been a great deal of interest in methodologies for developing common infrastructure of information that is reliable, maintainable and extensible. Since infrastructure was the part of the software development process, it is natural that the early efforts to improve the quality of infrastructure were concentrated on the programming aspect of software development. However, it is clear today that no programming methodology can overcome the errors and problems incurred in the functional specification phase of infrastructure development. The complexity of the information infrastructure specification task is well accepted but very few ideas for dealing with that complexity exist. A new approach is needed that enables the analyst to develop correct specifications that can be validated in terms of the information needs. The approach presented in this paper focuses on the problem definition for information systems that is based upon organization structure and functions. Social organizations are open systems as defined in general systems theory, and as such the functions of an organization may be analyzed in terms of a general model of open, living systems. With the amazing transformation of Internet-based technologies in recent years, for many organizations the main focus of attention and the main return on investment has shifted from the application specific focus to architecture specific. This is the main driver behind the migration from a framework and method for Technology Architecture to one for overall Enterprise Architecture. This paper describes the reference model that focuses on How Architecture of Information System & Flow can be implemented in today’s organizations, and one that is a "Common Systems Architecture" in Enterprise Continuum terms. This paper is contribution towards the framework of business applications architecture and its infrastructure applications parts - in order to provide help in addressing one of the key challenges facing the enterprise architect today: the need to design an integrated information infrastructure to enable ‘Boundaryless Information Flow'. These concepts are explained in detail in this paper.
