Data are the lifeblood of an organisation, being employed by virtually all business functions within a firm. Data management, therefore, is a critical process in prolonging the life of a company and determining the success of each of an organisation’s business functions.

Abstract:

An increasing number of organizations are implementing data warehouses to strengthen their decision support systems. This comes with the challenges of the population and the periodic update of data warehouses. In this thesis, we present a tool that provides users with features to create a warehouse database and transform structures of the source database into structures for the warehouse database. It is highly interactive, easy to use, and hides the underlying complexity of manual SQL code generation from its users. Attributes from source tables can be mapped into new attributes in the w

Abstract:

The amount of data accumulated by organizations have grown significantly during the last couple of years, increasing the importance of data quality. Ensuring data quality for large amounts of data is a complicated task, but crucial to subsequent analysis. This study investigates how to maintain and improve data quality in a data warehouse. A case study of the errors in a data warehouse was conducted at the Swedish company Kaplan, and resulted in guiding principles on how to improve the data quality. The investigation was done by manually comparing data from the source systems to the data integ

Abstract:

A database system for storing and querying data of a dynamic schema has been developed based on the kdb+ database management system and the q programming language for use in a financial setting of order and execution services. Some basic assumptions of mandatory fields of the data to be stored are made including that the data are time-series based.A dynamic schema enables an Order-Management System (OMS) to store information not suitable or usable when stored in log files or traditional databases. Log files are linear, cannot be queried effectively and are not suitable for the volumes produced

Abstract:

Conseguir informações que permitam a tomada de decisões baseadas num volumoso histórico de dados torna-se difícil quando as grandes empresas detêm um enorme volume de dados espalhados em diversos sistemas. Os sistemas de Data Warehouse surgiram da necessidade de transformar e organizar estes dados para a geração de informações estratégicas úteis. Com o avanço exponencial do progresso tecnológico, o ciclo de vida de desenvolvimento dos produtos torna-se menor, obrigando as empresas a tomarem decisões operacionais e estratégicas em curtos intervalos de tempo.
