Abstract:

Online Analytical Processing (OLAP) has become the de facto data analysis technology used in modern decision support systems. It has experienced tremendous growth, and is among the top priorities for enterprises. Open source systems have become an effective alternative to proprietary systems in terms of cost and function. The purpose of the study was to investigate the performance of two leading database storage engines in an open source OLAP environment. Despite recent upgrades in performance features for the InnoDB database engine, the MyISAM database engine is shown to outperform the InnoDB

Abstract:

[Truncated abstract] Many databases in scientific and business applications have grown exponentially in size in recent years. Accessing and using databases is no longer a specialized activity as more and more ordinary users without any specialized knowledge are trying to gain information from databases. Both expert and ordinary users face significant challenges in understanding the information stored in databases. The databases are so large in most cases that it is impossible to gain useful information by inspecting data tables, which are the most common form of storing data in relational data

On the other hand, Geographic Information Systems (GISs) provide a wide range of tools to analyze spatial phenomena and therefore must be included in the analysis phases of a decision support system (DSS).

Abstract:

As the rate of annual data generation grows exponentially, there is a demand to manage, query and summarise vast amounts of information quickly. In the past, frequency scaling was relied upon to push application throughput. Today, Dennard scaling has ceased, and further performance must come from exploiting parallelism. Vector architectures offer a highly efficient and scalable way of exploiting data-level parallelism (DLP) through sophisticated single instruction-multiple data (SIMD) instruction sets. Traditionally, vector machines were used to accelerate scientific workloads rather than busi

Abstract:

Over the last four decades, relational database systems, with their mathematical basis in first-order logic, have provided a congenial and efficient environment to handle enterprise data during its entire life cycle of generation, storage, maintenance and processing. An organic reason for their pervasive popularity is intrinsic support for declarative user queries, wherein the user only specifies the end objectives, and the system takes on the responsibility of identifying the most efficient means, called “plans”, to achieve these objectives. A crucial input to generating efficient query execu

Abstract:

The thesis discusses a series of related techniques that prepare and transform raw linguistic data for advanced processing in order to unveil hidden grammatical patterns. A threedimensional array is identified as a suitable data structure to build a data cube to capture multidimensional linguistic data in a computer's temporary storage facility. It also enables online analytical processing, like slicing, to be executed on this data cube in order to reveal various subsets and presentations of the data. XML is investigated as a suitable mark-up language to permanently store such an exploitable d

Abstract:

A evolução dos sistemas de Data Warehousing em dimensão e utilização impôs uma agitação contínua sobre os sistemas de processamento analítico. A materialização de estruturas multidimensionais de dados é, desde à muito, vista como uma forma de optimizar o tempo de resposta às interrogações de natureza agregada. Para além da temporalidade, é necessário considerar uma outra perspectiva: o espaço necessário para armazenar todas as agregações calculadas. Na prática, o problema da selecção de estruturas multidimensionais de dados traduz-se principalmente na escolha das vistas que mais evidenciam a d

Abstract:

Dissertação de mestrado em Sistemas de Dados e Processamento Analítico<br>A garantia da qualidade da água para consumo humano constitui um elemento essencial das políticas de saúde pública. A monitorização da qualidade da água em Estações de Tratamento de Água assenta em métodos analíticos cada vez mais sofisticados e eficientes, dispondo de mecanismos que registam automaticamente valores fiáveis dos diversos parâmetros que condicionam a qualidade da água. Face ao volume de dados armazenados, é necessário dotar as instituições de meios tecnologicamente avançados que proporcionem aos seus

Abstract:

Dissertação de mestrado em Engenharia de Informática<br>Nos últimos tempos os sistemas de bases de dados orientados por colunas têm atraído muita atenção, quer por parte de investigadores e modeladores de base de dados, quer por profissionais da área, com particular interesse em aspectos relacionados com arquiteturas, desempenho dos sistemas e sua escalabilidade ou em aplicações de suporte à decisão, nomeadamente em Data Warehousing e Business Inteligence. Ao contrário dos sistema de bases de dados mais tradicionais (“orientados à linha”), neste tipo de sistemas cada coluna de uma tabela de um
