Mark Logic Corporation introduced an enterprise-scale database specifically designed for content. Mark Logic Content Interaction Server enables organizations to build content-centric applications on their documents and business content, just as relational databases allowed applications to be built on numerical data. XML, SGML, XPath and XQuery serve as building blocks for Content Interaction Server to power parametric searches in conjunction with text search to deliver contextually relevant results. Content Interaction Server sees “inside” documents to identify precise sections of content (at any level of document granularity, chapter, paragraph, sentence, word, etc.) across an entire document collection. There is no need to pre-process the documents before loading them into the server. In addition to full XQuery support, Mark Logic has added extensions to XQuery to incorporate transactional update and more search capabilities.
