Zorba provides a pluggable store so it can be used on different kind of environments: disk, database, browser. By default, Zorba is built with a main memory store. 28msec implements a store on top of MongoDB. The XQuery in the Browser project has built a browser plugin for Zorba and leverages the DOM as its store.
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [ 1 ] and can be used to compute values (e.g., strings , numbers, or Boolean values ) from the content of an XML document.
The use of XML syntax also enables the use of XML-based tools for managing XSLT code. By contrast, XQuery syntax is more suitable for embedding in traditional programming languages such as Java (see XQuery API for Java) or C#. If necessary, XQuery code can also be expressed in an XML syntax called XQueryX.
Ranking in XML-Retrieval can incorporate both content relevance and structural similarity, which is the resemblance between the structure given in the query and the structure of the document. Also, the retrieval units resulting from an XML query may not always be entire documents, but can be any deeply nested XML elements, i.e. dynamic documents.
The event-driven model of SAX is useful for XML parsing, but it does have certain drawbacks. Virtually any kind of XML validation requires access to the document in full. . The most trivial example is that an attribute declared in the DTD to be of type IDREF, requires that there be only one element in the document that uses the same value for an ID attribu
An XML database is a data persistence software system that allows data to be specified, and stored, in XML format. This data can be queried , transformed, exported and returned to a calling system. XML databases are a flavor of document-oriented databases which are in turn a category of NoSQL database.
XML data binding refers to a means of representing information in an XML document as a business object in computer memory. This allows applications to access the data in the XML from the object, rather than using the DOM or SAX to retrieve the data from a direct representation of the XML itself.
The database system supports document store as well as key/value and graph data models with one database core and a unified query language AQL (ArangoDB Query Language).
