Application Program Interface. See application program, definition interface.
A set of public programmatic interfaces that consist of a language and message format to communicate with an operating system or other programmatic environment, such as databases, Web servers, JVMs, and so forth. These messages typically call functions and methods available for application development.
A server designed to host applications and their environments, permitting server applications to run. A typical example is OAS, which is able to host Java, C, C++, and PL/SQL applications in cases where a remote client controls the interface. See also Oracle Application Server.
A property of an element that consists of a name and a value separated by an equals sign and contained within the start tags after the element name. In this example, <Price units='USD'>5</Price>, units is the attribute and USD is its value, which must be in single or double quotes. Attributes may reside in the document or DTD. Elements may have many attributes but their retrieval order is not defined.
Business Components for Java.
A term describing the communication between businesses in the selling of goods and services to each other. The software infrastructure to enable this is referred to as an exchange.
A term describing the communication between businesses and consumers in the selling of goods and services.
External binary files that exist outside the database tablespaces residing in the operating system. BFILES are referenced from the database semantics, and are also known as External LOBs.
A Large Object datatype whose content consists of binary data. Additionally, this data is considered raw as its structure is not recognized by the database.
See Binary Large Object.
A programmatic technique in which one process starts another and then continues. The second process then calls the first as a result of an action, value, or other event. This technique is used in most programs that have a user interface to allow continuous interaction.
A stored program in Java or PL/SQL that adds the necessary functionality for the database to understand and manipulate a new datatype. Cartridges interface through the Extensibility Framework within Oracle 8 or 8i. interMedia Text is just such a cartridge, adding support for reading, writing, and searching text documents stored within the database.
See character data.
Channel Definition Format. Provides a way to exchange information about channels on the internet.
See Common Gateway Interface.
Cascading Style Sheets.
Text in a document that should not be parsed is put within a CDATA section. This allows for the inclusion of characters that would otherwise have special functions, such as &, <, >, etc. CDATA sections can be used in the content of an element or in attributes.
The generic acronym for the programming interfaces enabling Web servers to execute other programs and pass their output to HTML pages, graphics, audio, and video sent to browsers.
An element that is wholly contained within another, which is referred to as its parent element. For example <Parent><Child></Child></Parent> illustrates a child element nested within its parent element.
A utility that accepts an input file and creates a set of output classes that have corresponding functionality. In the case of the XML Class Generator, the input file is a DTD and the output is a series of classes that can be used to create XML documents conforming with the DTD.
The operating system environmental variable that the JVM uses to find the classes it needs to run applications.
The term used to describe the application architecture where the actual application runs on the client but accesses data or other external processes on a server across a network.
The LOB datatype whose value is composed of character data corresponding to the database character set. A CLOB may be indexed and searched by the interMedia Text search engine.
See Character Large Object.
The interface method in which the user enters in commands at the command interpreter's prompt.
An Object Management Group standard for communicating between distributed objects across a network. These self-contained software modules can be used by applications running on different platforms or operating systems. CORBA objects and their data formats and functions are defined in the Interface Definition Language (IDL), which can be compiled in a variety of languages including Java, C, C++, Smalltalk and COBOL.
The library of functions written in C that provides developers the ability to create code that can be easily ported to virtually any platform and operating system.
See Common Object Request Broker.
A DAD is a named set of configuration values used for database access. A DAD specifies information such as the database name or the SQL*Net V2 service name, the ORACLE_HOME directory, and NLS configuration information such as language, sort type, and date language.
A text fragment, which may be in XML format, that is returned to the requester embedded in an HTML page from a SQL query processed by the XSQL Servlet.
The term used as the tag name designating the DTD or its reference within an XML document. For example, <!DOCTYPE person SYSTEM "person.dtd"> declares the root element name as person and an external DTD as person.dtd in the file system. Internal DTDs are declared within the DOCTYPE declaration.
An in-memory tree-based object representation of an XML document that enables programmatic access to its elements and attributes. The DOM object and its interface is a W3C recommendation. It specifies the Document Object Model of an XML Document including the APIs for programmatic access. DOM views the parsed document as a tree of objects.
A set of rules that define the allowable structure of an XML document. DTDs are text files that derive their format from SGML and can either be included in an XML document by using the DOCTYPE element or by using an external file through a DOCTYPE reference.
See Document Object Model.
See Document Type Definition.
Electronic Data Interchange.
An independent program module that runs within a JVM on the server. CORBA provides the infrastructure for EJBs, and a container layer provides security, transaction support, and other common functions on any supported server.

An element without text content or child elements. It may only contain attributes and their values. Empty elements are of the form <name/> or <name></name> where there is no space between the tags.
A string of characters that may represent either another string of characters or special characters that are not part of the document's character set. Entities and the text that is substituted for them by the parser are declared in the DTD.
An open standard for describing data developed by the W3C using a subset of the SGML syntax and designed for Internet use. Version 1.0 is the current standard, having been published as a W3C Recommendation in February 1998.
The language used within stylesheets to transform or render XML documents. There are two W3C recommendations covering XSL stylesheets--XSL Transformations (XSLT) and XSL Formatting Objects (XSLFO).
(W3C) eXtensible Stylesheet Language, XSL consists of two W3C recommendations - XSL Transformations for transforming one XML document into another and XSL Formatting Objects for specifying the presentation of an XML document. XSL is a language for expressing stylesheets. It consists of two parts:
An XSL stylesheet specifies the presentation of a class of XML documents by describing how an instance of the class is transformed into an XML document that uses the formatting vocabulary.
