What is XQJ?
XQJ, the XQuery API for Java, is based on XQuery, a query language promulgated by the W3C that can operate both on physical XML documents, and also on virtual XML documents that have been derived from data sources such as relational or object databases. XQJ is a powerful new API standard developed for invoking XQuery expressions against virtually any XML or relational database and processing query results. XQJ makes the full power of the XQuery language available to Java applications. You can programmatically process the results in your Java code in a JDBC-like manner. XQJ is to XQuery what JDBC is to SQL.
The XQJ standard specifies a number of Java interfaces. The CentraSite XQJ interface implements the functionality defined by these interfaces, and thus makes XQJ available to the application; in addition, the CentraSite XQJ interface implements extensions that support CentraSite-specific features.
Note: | Beginning with version 8.2, CentraSite supports the final release of the XQJ specification (in contrast, earlier versions of CentraSite supported a preliminary release of the XQJ specification). Note that the XQJ interface that is implemented by current versions of CentraSite is not compatible with the interface that was implemented by versions of CentraSite prior to version 8.2. Documentation of the prior XQJ interface is available to Software AG customers who have a current maintenance contract in Empower. |
