Análise, projeto e implementação de um gerente web de metadados extensível para um processo de data warehousing.

Abstract

Decision Support Systems based in Data Warehouses has a critical component: the metadata. Known as “information about data”, metadata are required for understanding of data within time and, mainly, make the necessary instrument to turn them into knowledge. As organizations grew up, the problem with metadata has multiplied itself. However, metadata own problem presents good opportunity for software developers. In fact, this is more evident in the corporate Data Warehouse environment, because the users work on the process of taking companies decision, that acquire knowledge about all semantic involved in data’s formation. This work presents the analyses, design and implementation, of an Extensible Metadata Manager – The Metha Manager. The Metha Manager is a framework built for construction and use of a Metadata Repository for Data Warehouses, and it has, as main characteristic, the extensibility of its metadata to provide information for different types of tools that work on the process of Data Warehousing.
