INTEGRAÇÃO DE SISTEMAS EM EMPRESAS CORPORATIVAS DO SETOR PÚBLICO: UM ESTUDO DE CASO NA SECRETARIA DE EDUCAÇÃO DO ESTADO DA BAHIA

Abstract

Over time, public organizations are increasingly making use of Information Technology (IT), computerizing services to the community. Today, TI is one of the main pillars of public organizations. As the aim of providing better, more flexible and control the information, the integration between different systems and / or different architectures is a major organizational priorities. In addition, for public institutions, or even private, the integration of Information Systems (IS), has become a major challenge because of the legacy that is in production technologies and / or architectures that allow low rate for reuse. The organization was used as the basis for this study, the Education Department of the State of Bahia (SEC) has over the years its computer services. However, this process was gradual and, initially, decentralized, resulting in a very heterogeneous enterprise computing environment. It is very common to find in institutions such as used in this study the combined use of various systems with problems of integration and integrity of information. In the current situation of the SEC, the update and inclusion of new systems and technologies is a constant, making it vital to integrate the new systems with existing legacy, either, sharing data, processes or functions / requirements. Therefore, this work proposes a solution / standard for the development of new systems, allowing integration with legacy componentization of applying the requirements, through a Services Oriented Architecture (SOA - Service Oriented Architecture).
