Semi-structured Information Warehouses

چکیده
During the last decade, data warehouse and OLAP techniques have helped companies to gather, organize and analyze the structured data they produce. Simultaneously, digital libraries have applied Information Retrieval mechanisms to query their repositories of unstructured documents. In this context, the emergence of XML means the convergence of these two approaches, making possible the development of warehouses for semi-structured information. Although there exist several extensions of traditional data warehouse technology to manage semi-structured information, none of them are based on an underlying document model able to exploit this kind of information. Along this paper we expose our vision of what a semistructured information warehouse should be, by identifying a set of requirements throughout an example scenario.

Automating conceptual design of web warehouses
Web warehousing plays a key role in providing the managers with up-to-date and comprehensive information about their business domain. On the other hand, since XML is now a standard de facto for the exchange of semi-structured data, integrating XML data into web warehouses is a hot topic. In this paper we propose a semi-automated methodology for conceptual design of web warehouses from XML sourc...
متن کاملIndexing Real - World Data using Semi - Structured
We address the problem of deriving meaningful semantic index information for a multi-media database using a semi-structured document model. We show how our framework, called feature grammars, can be used to (1) exploit third-party interpretation modules for real-world unstructured components, and (2) use context-free grammars to convert such poorly or unstructured input to semi-structured outpu...
متن کاملDevelopment of Secure XML Data Warehouses with QVT
Context: Data warehouses are systems which integrate heterogeneous sources to support the decision making process. Data from the Web is becoming increasingly more important as sources for these systems, which has motivated the extensive use of XML to facilitate data and metadata interchange among heterogeneous data sources from the Web and the data warehouse. However, the business information t...
متن کاملSemi-automatic Discovery of Mappings Between Heterogeneous Data Warehouse Dimensions
Data Warehousing is the main Business Intelligence instrument for the analysis of large amounts of data. It permits the extraction of relevant information for decision making processes inside organizations. Given the great diffusion of Data Warehouses, there is an increasing need to integrate information coming from independent Data Warehouses or from independently developed data marts in the s...
متن کاملConceptual Design of Data Warehouses from E/R Schemes
Data warehousing systems enable enterprise managers to acquire and integrate information from heterogeneous sources and to query very large databases efficiently. Building a data warehouse requires adopting design and implementation techniques completely different from those underlying information systems. In this paper we present a graphical conceptual model for data warehouses, called Dimensi...
