ExTENSIBLE MARKUP LANGUAGE (xML) SCHEMAS FOR DATA VAULT MODELS
نویسندگان
چکیده
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.

A Web-Based Metadata Schema Repository
The metadata schema of a digital archive describes the structure and attributes of metadata. Analysis and definition of metadata schema for a new digital archive must be carefully carried out and determined at the first stage of development. To ease the task, we used an Extensible Markup Language (XML) structure to represent the metadata schema, and then designed and implemented a metadata sche...

Securing electronic data has evolved into an important requirement in domains such as health care informatics, with the eXtensible Markup Language (XML) utilized to create standards such as the Clinical Document Architecture and the Continuity of Care Record, which have led to a need for approaches to secure XML schemas and documents. In this paper, we present a method for generating eXtensible...

The ability of providing a “standardized, extensible means of coupling semantic information within documents describing semistructured data” (Chaudhri, Rashid, & Zicari, 2003) has led to a steady growth of XML (extensible markup language) data sources, so that XML is touted as the driving force for representing and exchanging data on the Web. The motivation behind any clustering problem is to f...
