Bluestream XStreamDB

XStreamDB™ is a native XML database server for storage and retrieval of XML documents. Customers find XstreamDB to be a robust, extensible, yet lightweight database application useful for content management, web publishing, and enterprise application integration. It has a transaction-based architecture, support for XQuery with update extensions, XML Schemas, value and full text indexes, resource locking, and WebDAV sharing. It is accessible using a Java API, or the included XStreamDB™ Explorer application for configuration, ad hoc queries, and administration.

Features

The power of XStreamDB comes from the following features:

• XQUERY Powerful, purpose-built XML Query language developed by the W3C provides a rich programmatic language for search, manipulation, and control of XML documents.
• XQUERY EXTENSIONS XStreamDB has many other extensions to XQuery including:
• Stored XQuery Function Modules
• Precompiled module functions for improved performance
• Integrated Update Language - any node update
• XSLT transform function
• JDBC Connector function
• Parameterized Queries
• JAVA SERVER Built using Pure Java technology, deployable on any platform that supports the Java VM 1.4 or greater, including Windows, Mac, Linux and other Unix-based operating systems.
• ZERO ADMINISTRATION Easy to install, and requires no administrative procedures, such as index compaction or disk compaction. Supports hot backup, scheduled or immediate.

• JAVA CLIENT API Uses a familiar JDBC-like client, the Java API provides broad programmatic control over data and document content.

• INDEXING Index XML content by multiple value indexes and/or a full-text index. Indexes create a perpetual dictionary for element and attribute level searches over document collections.
• FULL-TEXT SEARCH Finds text within document content using wildcard matching, word proximity, and/or phrase matching. Matches results to elements or attributes in matching documents. Instantaneous queries through full text indexing.
• SCHEMA VALIDATION Schema manager loads either DTD or W3C schemas. When a schema is attached to a root, the schema validation rules are enforced on all XML documents stored there. Because schemas are enabled as resources with URIs, other web applications can freely access the schemas.
• SUPPORT FOR ATTACHMENTS Non-XML content, such as documents, images, or other digital assets, are stored as binary files, and identified with its associated mimetype.
• RESOURCE MANAGER Any document, schema or binary can be enabled as a web resource. Once enabled, a web resource can be accessed using WebDav or the XdbWeb web application. As well, the Resource API allows applications to access resources directly.
• WEBDAV XStreamDB makes resources accessible as URIs using its WebDAV connector. Documents and resource categories in the server appear as Web folders and files to a WebDAV client. WebDAV is supported in the operating system, or directly in applications which include XMLSpy and XMetaL.
• SECURITY XStreamDB supports users, groups, and permission scoping for a complete and easy to use permissions system. Extended, user definable permissions and Http digest authentication are further features that make application writing easier with XStreamDB.
