In the earlier period, large enterprise, developed its management reports system based on files system and the 3rd-generation language. The managers of several departments access management information from the reports system. Because competition stress increasing quickly and information requirement changing frequently, the legacy system could not satisfy the information need of managers. The maintainability of legacy system is decreasing, and the cost is growing up. How to solve the difficulties on system maintenance ? System reengineering is commonly used as a solution. How to choose a good migration strategy is also a big issue. This research focuses on finding a migration strategy for the legacy systems and a methodology of developing EIS based on users¡¦ needs via current new information technologies. The methodology is applied to implement a EIS for a large enterprise in order to verify the feasibility of the methodology. A questionnaire investigation among the users of the new system has clearly shown a fairly good users¡¦ satisfaction.

Nesta dissertação, são discutidas as vantagens e dificuldades de um Sistema Gerencial de Apoio a Decisão em um ambiente Intranet/Internet, sua execução, bem como a utilização de aplicações de bancos de dados na web. Um sistema dessa natureza, denominado SAG (Sistema de Apoio Gerencial), foi concebido para dar suporte às atividades de gerência, supervisão e controle da rede de distribuição de energia elétrica da Eletropaulo Metropolitana (São Paulo, Brasil). O SAG possibilita o estabelecimento de uma sistemática de supervisão, visando, a partir da análise das condições atuais da rede de distribuição e em função dos recursos disponíveis, permitir o acompanhamento da evolução da qualidade do fornecimento de energia elétrica. Disponibilizando informações que irão orientar ações para corrigir os possíveis desvios inadequados e fixar políticas e diretrizes a serem seguidas nos níveis gerenciais. Como resultado, é esperado tornar mais ágil o processo decisório, bem como o acesso a dados técnicos e de carregamento dos equipamentos da rede de distribuição. / In this dissertation are discussed the advantages and difficulties of an Executive Information System (EIS) implementation on an Intranet or Internet environment, as well as the use of Database applications on the web.

The ROC Government began to develope its e-Government- Infrastructure since 1997, and up-to-date is expanding the e-Taiwan Project as a whole by Executive Yuan. The computerization of administration processes within various government agencies push forward fast development of administration information systems via handling administrative works and lead to utmost opportunities for the government statistics by means of very large databases. Starting from a survey on developements of e-Government, administrative processes for interior affairs, and knowledge mining as well as discovery techniques, this study brings out reference data models, potential statistical softwaretools, and an experimental framework as a whole for knowledge discovery in the context of e-Government. In the next step, this study experiments with applying clustering techniques such as K-means, ANN, and Twostep on datamart regarding marriage of foreigners ( including citizens from Mainland China ) in Taiwan, and with employeeing multi-modes approach on population forecasting. The results of aforementioned analysises are feed into backend database. At last, this author carries out a prototype of knowledge discovery system which includes front-end data base, data marts, knowledge base and interfaces to EIS. The results of the research can be summarized as following: 1.Knowledge derived by means of data mining is capable to represent social events / affairs as well as to serve as a kind of guideline for developing government ploicies. 2. The modern data-ming techniques and classical data-analysis approaches complement with each other in the system developed in this research. 3. Certain mining technique is suitable of corresponding data pattern, for example, expotential smoothing is more suitable for our population data than ANN, which means that we may often achieve better result by multi-mode analysis and comprison with the outputs of different modes. 4. Knowledge creation, sharing, and management can be achieved by means of the knowledge discovery processes on the framework developed in this research. 5. We can figure out errorful raw data in the mining output and feedback to the data source to improve its quality.
