ZapNote: NeoCore

Rather than being forced to map XML documents to an alternate data representation format or insert an entire XML document into a single field as is the case with XML-enabled RDBMS, the Native XML Data Store (NXD) can accept XML documents for storage and retrieval without any modifications, mapping, or transformations. NeoCore provides a patented NXD approach that assigns a unique fingerprint called an "icon" to each XML document and then applies hashing and storage techniques to these iconic representations. This approach allows the user to experience speed and indexing improvements over other methods of XML storage and retrieval and exploits XML structure by self-constructing the data store, reducing development time.

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.

“When Will XML’s Time Come?”

In financial services, the picture is murkier. Plenty of financial service providers have implemented XML. But too many companies are trying to be the first to gain a competitive advantage with XML-based systems, and then force their own standards on their partners. The result: confusion, acrimony and duplication of effort, says Ron Schmelzer, founder and senior analyst with XML market researcher ZapThink LLC.

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: 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.
