Nos dias de hoje o acesso à informação por parte das empresas é vital para o bom desempenho das suas funções. As empresas de telecomunicações não fogem à regra, a sua posição no mercado está dependente das decisões que são tomadas com base na avaliação dessa informação. Para suportar os processos de apoio à decisão é coerente recorrer-se a Data Warehouses que permitem integrar informação de diversas fontes, verificando a sua qualidade, actualização e coerência, organizando-a para um fácil acesso e consulta de vários pontos de vista. Numa empresa de telecomunicações móvel, um Data Mart geográfico baseado na informação de tráfego da companhia que pode identificar as localizações preferenciais dos utilizadores na rede é muito importante porque fornece indicadores muito úteis para o departamento de marketing e negócio da empresa de maneira a que se saiba onde e como actuar para permitir que esta se desenvolva e ganhe vantagem no mercado. ABSTRACT: Today the access to information by enterprises is vital for the company’s performance. Telecommunications companies are no exception. Their position in the market is dependent on the decisions that are taken based on the evaluation of such information. To support the decision making process Data Warehouse is today an extremely useful tool; it integrates information from different sources, checking on its validity, quality and update, coherence, organizing it for an easy access and search from various perspectives. ln a mobile telecommunications company a geographical Data Mart-based traffic information that can identify the preferential locations of users on the network is very important It provides useful indicators to the Department of Marketing and Business there by allowing you to know where and how to act and boosting the development of the company.

Montados form a heterogeneous landscape of wooded matrix dominated by cork and/or holm oak with open areas characterized by fuzzy boundaries. Montado supports a high biological diversity associated to low intensity management and a landscape diversity provided by a continuous gradient of land cover. Among other features this permits the classification of montados as a High Nature Value (HNV) system. We assessed the role of birds as HNV indicators for montado, and tested several bird groups—farmland, edge, forest generalists and forest specialists species; and some universal indicators such as species conservation status, Shannon’s diversity index and species richness. Our study areas covered the North–South distribution of cork oak in Portugal, and we surveyed the breeding bird communities across 117 sampling sites. In addition to variables related to management and sanitary status, we considered variables that characterize the landscape heterogeneity inside the montado—trees and shrub density and richness of woody vegetation. Our results suggest that specific bird guilds can be used as HNV indicators of particular typologies of montado, and highlight the need to develop an indicator that could be transversally applied to all types of montado.
