Modelo de arquitectura tecnológica de sistemas de informação na UEM

Abstract

Within the context of Information Systems, a reference model is defined as a generically accepted representation that allows people to agree on definitions, build common perceptions and identify challenges to solve. A technological reference model is needed to establish a context of perception of how the various technologies needed to implement Information Systems management relate to each other. The Information Systems Technological Architecture (ATSI) defines the basic structure for the development of an Organization's Information Systems. ATSI is not specifically intended to be a Systems Architecture, however, it does contain specific policies and procedures for planning and approving technology resources. It provides the necessary standards for implementation in any procurement process and also identifies other standards that will be needed depending on the type of system. All of these standards aim to provide greater portability (ability to change a system from one platform to another), scalability (ability to use the same application software on different platforms from personal computers to super computers) and interoperability (ability of two or more systems or components exchange and use application data across different hardware/software platforms) as well as help achieve long-term goals. The implementation of these standards creates an open systems environment that is important for operations inside and outside the Organization. In this context, using a methodology oriented to two merely descriptive approaches, this work sought to clarify the concepts associated with Information Systems per se and the application of architectures in Information Systems, to propose a reference model for the Technological Architecture of Information Systems, having created a vision for the IS of UEM and identified technological principles that guided the construction of the reference model proposed for the Technological Architecture of Information Systems that adapts to the reality of an Organization, in this case the UEM
