The specification defines the data type XML, functions for working with XML, including element construction, mapping data from relational tables, combining XML fragments, and embedding XQuery expressions in SQL statements. Functions which can be embedded include XMLQUERY (which extracts XML or values from an XML field) and XMLEXISTS (which ...
XQuery provides the means to extract and manipulate data from XML documents or any data source that can be viewed as XML, such as relational databases [9] or office documents. XQuery contains a superset of XPath expression syntax to address specific parts of an XML document. It supplements this with a SQL-like "FLWOR expression" for performing ...
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.
XML is `shredded` into a series of Tables based on a Schema [5] XML is stored into a native XML Type as defined by ISO Standard 9075-14 [6] RDBMS that support the ISO XML Type are: IBM DB2 (pureXML [7]) Microsoft SQL Server [8] Oracle Database [9] PostgreSQL [10] Typically an XML-enabled database is best suited where the majority of data are ...
An XML data generation tool to generate an arbitrary number of XML documents with well-defined value distributions and referential integrity across documents. The XML data is generated conforming to industry schema such as FIXML to model real-world applications. Workloads which are executed on the generated data. A workload is a set of ...
XML databases are a subclass of document-oriented databases that are optimized to work with XML documents. Graph databases are similar, but add another layer, the relationship, which allows them to link documents for rapid traversal. Document-oriented databases are inherently a subclass of the key-value store, another
Its design is similar to the JDBC API which has a client/server feel and as such lends itself well to Server-based XML Databases and less well to client-side XQuery processors, although the "connection" part is a very minor part of the entire API. Users of the XQJ API can bind Java values to XQuery expressions, preventing code injection attacks ...
SQLXML may refer to: . SQL/XML, extension to the SQL standard that specifies SQL-based extensions for using XML in conjunction with SQL; SQLXML, a technology to support XML for Microsoft SQL Server 2000, being mostly deprecated (see Microsoft Data Access Components
