EXTENSIBLE MARKUP LANGUAGE (XML) SCHEMAS FOR DATA VAULT MODELS

摘要

With the conceptualization of next generation architecture for Data Warehousing, that is the DW 2.0, there is now an increased emphasis on using fully-temporalized databases, in particular with approaches such as the Data Vault. In this paper we present a template XML Schema for Data Vault model concepts (at a metamodel level) and a process for creating XML Schemas for data warehouse designs represented as Data Vault models. These templates can be used to describe and present data from disparate systems in a structured format suitable for exchange and loading into a data warehouse.
