XQJ
XQuery API for Java (XQJ) refers to the common Java API for the W3C XQuery 1.0 specification. The XQJ API enables Java programmers to execute XQuery against an XML data source (e.g. an XML database) while reducing or eliminating Vendor lock-in, vendor lock in. The XQJ API provides Java developers with an interface to the XQuery Data Model. Its design is similar to the Java Database Connectivity, JDBC API which has a client/server feel and as such lends itself well to Server-based XML database, XML Databases and less well to client-side XQuery processors, although the "Database connection, connection" part is a very minor part of the entire API. Users of the XQJ API can bind Java (programming language), Java values to XQuery expressions, preventing Code injection, code injection attacks. Also, multiple XQuery expressions can be executed as part of an atomic transaction. History and implementation The XQuery API for Java was developed at the Java Community Process as Java Spec ...

BaseX
BaseX is a native and light-weight XML database management system and XQuery processor, developed as a community project on GitHub. It is specialized in storing, querying, and visualizing large XML documents and collections. BaseX is platform-independent and distributed under the BSD-3-Clause license. In contrast to other document-oriented databases, XML databases provide support for standardized query languages such as XPath and XQuery. BaseX is highly conformant to World Wide Web Consortium (W3C) specifications and the official Update and Full Text extensions. The included GUI enables users to interactively search, explore and analyze their data, and evaluate XPath/XQuery expressions in realtime (i.e., while the user types). Technologies * XPath query language * XQuery 3.1 ** XQuery Update (W3C) ** XQuery Full Text (W3C) * Support for most EXPath/EXQuery modules and packaging system * Client-Server architecture with user and transaction management and logging facilities * ...

EXist
eXist-db (or eXist for short) is an open source software project for NoSQL databases built on XML technology. It is classified as both a NoSQL document-oriented database system and a native XML database (and it provides support for XML, JSON, HTML and Binary documents). Unlike most relational database management systems (RDBMS) and NoSQL databases, eXist-db provides XQuery and XSLT as its query and application programming languages. eXist-db is released under version 2.1 of the GNU LGPL. Features eXist-db allows software developers to persist XML/JSON/Binary documents without writing extensive middleware. eXist-db follows and extends many W3C XML standards such as XQuery. eXist-db also supports REST interfaces for interfacing with AJAX-type web forms. Applications such as XForms may save their data by using just a few lines of code. The WebDAV interface to eXist-db allows users to "drag and drop" XML files directly into the eXist-db database. eXist-db automatically indexes d ...

Java Community Process
The Java Community Process (JCP), established in 1998, is a formalized mechanism that allows interested parties to develop standard technical specifications for Java technology. Anyone can become a JCP Member by filling a form available at thJCP website JCP membership for organizations and commercial entities requires annual fees – but is free for individuals. The JCP involves the use of Java Specification Requests (JSRs) – the formal documents that describe proposed specifications and technologies for adding to the Java platform. Formal public reviews of JSRs take place before a JSR becomes ''final'' and the JCP Executive Committee votes on it. A final JSR provides a ''reference implementation'' that is a free implementation of the technology in source code form and a ''Technology Compatibility Kit'' to verify the API specification. A JSR describes the JCP itself. , JSR 387 describes the current version (2.11) of the JCP. List of JSRs There are hundreds of JSRs. Some ...

Java API
There are two types of Java programming language application programming interfaces (APIs): * The official core Java API, contained in the Android (Google), SE (OpenJDK and Oracle), MicroEJ. These packages (java.* packages) are the core Java language packages, meaning that programmers using the Java language had to use them in order to make any worthwhile use of the Java language. * Optional APIs that can be downloaded separately. The specification of these APIs are defined according to many different organizations in the world (Alljoyn, OSGi, Eclipse, JCP, E-S-R, etc.). The following is a partial list of application programming interfaces (APIs) for Java. APIs Following is a very incomplete list, as the number of APIs available for the Java platform is overwhelming. ; Rich client platforms * Eclipse Rich Client Platform (RCP) * NetBeans Platform ;Office_compliant libraries * Apache POI * JXL - for Microsoft Excel * JExcel - for Microsoft Excel ;Compression * LZM ...

XQuery
XQuery (XML Query) is a query and functional programming language that queries and transforms collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats (JSON, binary, etc.). The language is developed by the XML Query working group of the W3C. The work is closely coordinated with the development of XSLT by the XSL Working Group; the two groups share responsibility for XPath, which is a subset of XQuery. XQuery 1.0 became a W3C Recommendation on January 23, 2007. XQuery 3.0 became a W3C Recommendation on April 8, 2014. XQuery 3.1 became a W3C Recommendation on March 21, 2017. Features XQuery is a functional, side effect-free, expression-oriented programming language with a simple type system, summed up by Kilpeläinen: 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 or office documents.

XML Database
An XML database is a data persistence software system that allows data to be specified, and sometimes 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. Rationale for XML in databases There are a number of reasons to directly specify data in XML or other document formats such as JSON. For XML in particular, they include: * An enterprise may have a lot of XML in an existing standard format * Data may need to be exposed or ingested as XML, so using another format such as relational forces double-modeling of the data * XML is very well suited to sparse data, deeply nested data and mixed content (such as text with embedded markup tags) * XML is human readable whereas relational tables require expertise to access * Metadata is often available as XML * Semantic web data is available as RDF/XML * Provides a solution for Objec ...

Java Package
A Java package organizes Java classes into namespaces, providing a unique namespace for each type it contains. Classes in the same package can access each other's package-private and protected members. In general, a package can contain the following kinds of types: classes, interfaces, enumerations, and annotation types. A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all have to do with a specific application or perform a specific set of tasks. Programmers also typically use packages to organize classes belonging to the same category or providing similar functionality. Using packages In a Java source file, the package that this file's class or classes belong to is specified with the package keyword. This keyword is usually the first keyword in the source file. At most one package declaration can appear in a source file. package java.awt.event; To use a package's classes inside a Java source ...

XQuery Update Facility
XQuery Update Facility is an extension to the XML Query language, XQuery. It provides expressions that can be used to make changes to instances of the XQuery 1.0 and XPath 2.0 Data Model. It became a W3C Candidate Recommendation on 31 July 2009 and was finalised as Recommendation on 17 March 2011. A version to work with XQuery 3.0 was drafted, but was never completed, and is archived as a W3C Working Group Note.

Document Object Model
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. Nodes can have event handlers attached to them. Once an event is triggered, the event handlers get executed. The principal standardization of the DOM was handled by the World Wide Web Consortium (W3C), which last developed a recommendation in 2004. WHATWG took over the development of the standard, publishing it as a living document. The W3C now publishes stable snapshots of the WHATWG standard. In HTML DOM (Document Object Model), every element is a node: * A document is a document node. * All HTML elements are element nodes. * ...

Simple API For XML
SAX (Simple API for XML) is an event-driven online algorithm for parsing XML documents, with an API developed by the XML-DEV mailing list. SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM). Where the DOM operates on the document as a whole—building the full abstract syntax tree of an XML document for convenience of the user—SAX parsers operate on each piece of the XML document sequentially, issuing parsing events while making a single pass through the input stream. Definition Unlike DOM, there is no formal specification for SAX. The Java implementation of SAX is considered to be normative. SAX processes documents state-independently, in contrast to DOM which is used for state-dependent processing of XML documents. Benefits A SAX parser only needs to report each parsing event as it happens, and normally discards almost all of that information once reported (it does, however, keep some ...
