XML Data Storage Technologies & Trends
While file systems, relational, and object-oriented database management systems have met our needs in prior years for data storage and retrieval, XML imposes new requirements on how that information needs to be stored so that it can be retrieved in a structured, hierarchical manner. This ZapThink report, “XML Data Storage Technologies and Trends” covers the various commercial options that focus on meeting the requirements for XML storage and retrieval, and identifies benefits, disadvantages, key market drivers, and sizing and growth of the market for these products.

ZapNote: eXcelon
There are two major categories of XML data store: extensions to relational database systems (RDBMS) and a new category of "Native" XML data stores (NXDs). While extensions to RDBMS systems simply enable RDBMS databases to map XML documents to relational tables, NXDs allow users to insert XML documents directly into the system without need for mapping or interacting with anything besides the XML document. eXcelon’s eXtensible Information Server (XIS) is an "XML data management system (XDBMS)" that is aimed squarely at the problem of storing arbitrarily structured XML documents. Among other features, XIS provides node level management of XML data, dealing with XML document information at the element level, rather than the document level.
ZapNote: Infonyte
The increasing use of XML is necessitating a general storage and retrieval system that can handle the specific needs of XML document archival. Infonyte provides a Native XML Data store (NXD) solution that is a compact called Infonyte-DB that uses a persistent implementation of the Document Object Model (DOM) as its primary storage mechanism.
ZapNote: Altova
While previous versions of Altova’s XML Spy product were focused on serving solely the needs of XML developers, the new version of the product adds a new market — XML content creators and users. The Austrian company hopes to bring XML spy from developer-focused IDE to a comprehensive product line that covers two major markets: developers and non-technical content users.
ZapNote: XML Global
Starting from roots in the text search engine business, XML Global has produced a platform called GoXML Transform that aims to provide a means for storing and manipulating native XML data. Leveraging Java and this text search experience, GoXML provides a combined Native XML data store, search engine, registry, and enterprise-class transformation and mapping system.
ZapNote: XYZFind
XYZFind provides a general-purpose NXD storage and retrieval system for XML documents, regardless of their content or schema. XYZFind aims to solve the problem of search and query over identifiable "islands of data" where the content its too varied to accommodate with file system tools. XYZFind’s utilizes a proprietary query language and has a proprietary, text-based storage architecture that utilizes a meta-schema encompassing an aggregate, schema-independent view of the data.
