An ETL Metadata Model for Data Warehousing
Metadata is essential for understanding information stored in data warehouses. It helps increase levels of adoption and usage of data warehouse data by knowledge workers and decision makers. A metadata model is important to the implementation of a data warehouse; the lack of a metadata model can lead to quality concerns about the data warehouse. A highly successful data warehouse implementation...
متن کاملGraph-based ETL Processes for Warehousing Statistical Open Data
Warehousing is a promising mean to cross and analyse Statistical Open Data (SOD). But extracting structures, integrating and defining multidimensional schema from several scattered and heterogeneous tables in the SOD are major problems challenging the traditional ETL (Extract-Transform-Load) processes. In this paper, we present a three step ETL processes which rely on RDF graphs to meet all the...
متن کاملAn Integrative and Uniform Model for Metadata Management in Data Warehousing Environments
Due to the increasing complexity of data warehouses , a centralized and declarative management of metadata is essential for data warehouse administration, maintenance and usage. Metadata are usually divided into technical and semantic metadata. Typically, current approaches only support subsets of these metadata types, such as data movement meta-data or multidimensional metadata for OLAP. In pa...

Requirements from all over the bank have to be met by FDWH projects in an ongoing proce...
متن کاملKnowledge and Metadata Integration for Warehousing Complex Data
With the ever-growing availability of so-called complex data, especially on the Web, decision-support systems such as data warehouses must store and process data that are not only numerical or symbolic. Warehousing and analyzing such data requires the joint exploitation of metadata and domain-related knowledge, which must thereby be integrated. In this paper, we survey the types of knowledge an...
