Abstract(s)
Atualmente, com a evolução tecnológica e o crescente volume de informação
produzida que é necessário armazenar, passou a ser necessário que os Sistema de Gestão de
Bases de Dados (SGBD) se multiplicassem com características específicas.
A Direção de Tecnologias de Informação e Comunicação (DITIC), por força da sua
missão, foi ao longo dos anos desenvolvendo internamente várias aplicações que utilizam
vários SGBD distintos.
Neste contexto, esta investigação tem por objetivo avaliar a implementação de um
SGBD único nas aplicações desenvolvidas internamente na DITIC e visa identificar os
SGBD existentes e utilizados, os requisitos que devem ser acautelados, verificar as
vantagens e desvantagens de utilizar um SGBD único e os impactos esperados caso se
pretenda migrar o SGBD das aplicações atualmente em exploração.
Os resultados revelam que a DITIC utiliza vários dos principais SGBD no mercado e
que por imposições legais e estratégias deve optar por soluções de código aberto.
Adicionalmente, face à heterogeneidade de aplicações existentes e que lhe são solicitadas,
não é possível utilizar um SGBD único, devendo, no entanto, ser uniformizado sempre que
possível.
Abstract: Nowadays, with the technological evolution and the increasing volume of information that needs to be stored, it also become necessary to have Database Management System (DBMS) with specific characteristics, making the number and type of DBMS to multiply. The Directorate of Information and Communication Technologies (DITIC), by virtue of its mission, has over the years developed several applications that use different DBMS. In this context, this research aims to identify existing DBMS for DITIC developed applications and evaluate the requirements, advantages, disadvantages and impact of the migration of the current running applications to a single DBMS. The results show that DITIC uses several of the main DBMS in the market and that due to legal impositions and strategies should opt for open source solutions. In addition, given the heterogeneity of existing and under development applications, it is not possible to use a single DBMS, but should be standardized whenever possible.
