Unfortunately, no standard XML data warehouse architecture emerges. ... Data warehousing and OLAP applications must nowadays handle complex data that are not only numerical or symbolic. The XML language is well-suited to logically and physically represent complex data. ... The authors show how data warehouse multidimensional design may be carried out starting directly from XML sources. ...arXiv:1701.08033v1 fatcat:dfuzbfzhizhapnp5kuqxtujq6e

Interchanging metadata between software components of a data warehouse environment is the foundation for leveraging the various benefits of an integrated metadata management for data warehousing. ... We therefore propose a software architecture for metadata interchange that incorporates a shared metamodel to agree on metadata syntax and semantics, XML as a standard interchange language, and XML Metadata ... Future research will concentrate on how to integrate metadata that cannot be extracted from DWH components, but resides in various other sources. ...doi:10.1007/3-540-36128-6_1 fatcat:cvraztumgfchdg7mlv6rfyl6ni

XML is suitable for structuring complex data coming from different sources and supported by heterogeneous formats. It allows a flexible formalism capable to represent and store all types of data. ... We propose an XML-based methodology, called X-Warehousing, which designs warehouses at a logical level, and feeds them with XML documents at a physical level. ... Our approach does not only use the XML formalism to design data warehouses (or data cubes), but also feeds them with data. We use XML documents to support information relative to the designed facts. ...doi:10.1007/11827252_6 fatcat:itg5fqrbhrfynlzefdyttgtaue
