free ebook and tutorial - Querying XML Views of Relational Data

XML has emerged as the standard data exchange format for Internet-based business applications. This has created the need to publish existing business data, stored in relational databases, as XML. A general way to publish relational data as XML is to provide XML views over relational data, and allow business partners to query these views using an XML query language. In this paper, we address the problem of evaluating XML queries over XML views of relational data.

free ebook and tutorial - XML Metadata Services

As the Service Oriented Architecture (SOA) principles have gained importance, an emerging need has appeared for methodologies to locate desired services that provide access to their capability descriptions. These services must typically be assembled into short-term service collections that, together with code execution services, are combined into a meta-application to perform a particular task. To address metadata requirements of these problems, we introduce XML Metadata Services to manage both stateless and stateful (transient) metadata.

free ebook and tutorial - XML with SQL

Most business data are stored in relational database systems, and SQL (Structured Query Language) isused for data retrieval and manipulation. With XML (Extensible Markup Language) rapidly becoming the defacto standard for retrieving and exchanging data, new functionality is expected from traditional databases. Existing SQL applications will evolve to retrieve relational data as XML data using database or SQL extensions for XML. New XML data will be stored, searched, and manipulated in the database as a “first class” citizen along with existing relational data.

free ebook and tutorial - Wf_XML Binding

This document represents a specification for an XML language designed to model the data transfer
requirements set forth in the Workflow Management Coalition’s Interoperability Abstract specification (WFMC-TC-1012) [1]. This language will be used as the basis for concrete implementations of the functionality described in the abstract in order to support the WfMC’s Interface 4 (as defined by the workflow reference model [2]).
