Modelo de arquitectura para a distribuição de componentes tecnológicos de sistemas de informação do schoolnet Moçambique

Abstract

The development of an organization's Information Systems (IS) should result from a reflection on the role they should play, as well as on the processes and resources involved during their construction. An architecture is seen as a set of descriptive representations (models) relevant to the description of an object so that it can be built according to requirements and maintained over time. The architecture for the distribution of technological components of information systems defines a set of standards (standards) necessary for implementation in any IS or information technology (IT) acquisition or development process, as well as the interconnection between them (IS and IT), the organization and the end user. Taking into account the organization's visions and principles, these standards, which serve as a guide for the standardization of technologies, will have to be redesigned from time to time as these (technologies) are in constant evolution. In this work, we propose an architectural model that makes it possible to distribute the technological components of an organization's Information Systems, in this case SchoolNet Moçambique (SNM). Descriptive in nature, this work reflects the course of the work carried out in the fulfillment of the objectives imposed on this project, and it comprises seven chapters. In the first chapter, there is initially a brief introduction to the work, followed by the presentation of the definition of the problem that served as motivation for the realization of this thesis. Also described in this chapter are the objectives (general and specific) to be achieved, the methodologies used to prepare the work and the definition of its boundaries. Chapters 2 and 3 review and systematize the theoretical foundations and concepts related to Information Systems (IS), Information Technologies (IT) and Information Systems Management (GSI). Chapter 4 is dedicated to the characterization of the organization under study, in this case SchoolNet Moçambique. Chapter 5 presents the Model, which begins with the definition of the visions and principles that will guide the Model and ends with the discretion of the layers that constitute it. The conclusions and recommendations are presented in chapter 6, followed by the bibliography used and the annexes.
