NLM APIs. An Application Programming Interface (API) is a set of routines that an application uses to request and carry out lower-level services performed by a computer's operating system. For computers running a graphical user interface, an API manages an application's windows, icons, menus, and dialog boxes. We invite you to develop computer and mobile applications using National Library of Medicine (NLM) resources. We request that any application that makes use of NLM data include the following statement: "This product uses publicly available data from the U.S.

National Library of Medicine (NLM), National Institutes of Health, Department of Health and Human Services; NLM is not responsible for the product and does not endorse or recommend this or any other product. " Service-oriented architecture. Service-oriented architecture (SOA) is a software design and software architecture design pattern based on discrete pieces of software providing application functionality as services to other applications.

Service-oriented architecture

This is known as service-orientation. It is independent of any vendor, product or technology.[1] A service is a self-contained unit of functionality, such as retrieving an online bank statement.[2] Services can be combined by other software applications to provide the complete functionality of a large software application.[3] SOA makes it easy for computers connected over a network to cooperate. Every computer can run an arbitrary number of services, and each service is built in a way that ensures that the service can exchange information with any other service in the network without human interaction and without the need to make changes to the underlying program itself. Overview[edit]

Service Component Architecture. Service Component Architecture (SCA) is a software technology created by major software vendors including IBM, Oracle and TIBCO.

Service Component Architecture

SCA provides a model for composing applications that follow Service-Oriented Architecture principles.[1] The technology encompasses a wide range of disparate technologies and as such is specified in various independent specifications in order to maintain programming language and application environment neutrality.[1] Partners[edit] Partner vendors include: WebSphere Application Server V7 Feature Pack for Service Component Architecture - FAQ. What is Service Component Architecture?

Service Component Architecture (SCA) was conceived through industry collaboration to provide a language-neutral programming model for building applications based on Service Oriented Architecture. First published in 2005, the Open SOA Collaboration ( finalized the SCA 1.0 specification and submitted to OASIS for standardization in March 2007. The SCA programming model benefits architectures where business function is partitioned as a set of services.

Open SOA Collaboration. Last month an alliance of leading vendors announced progress on specifications to define a language-neutral programming model for application development in SOA environments.

Open SOA Collaboration

They call this specification Open SOA Collaboration. In essence, they are proposing a new standard to create and manage IT, making the process of integrating different third-party SOA technologies "less onerous," they say. Or, we can call this a standard way of delivering services, making it easier to work and play well together.

So, who's in the gang? OASIS (organization) The Organization for the Advancement of Structured Information Standards (OASIS) is a global consortium that drives the development, convergence, and adoption of e-business and web service standards.

OASIS (organization)

With its headquarters in the United States, members of the consortium decide how and what work is undertaken through an open, democratic process.[1] Technical work is being carried out under the following categories: Web Services, e-Commerce, Security, Law & Government, Supply Chain, Computing Management, Application Focus, Document-Centric, XML Processing, Conformance/Interop, and Industry Domains. OASIS was first formed as SGML Open in 1993 as a trade association of SGML tool vendors to cooperatively promote the adoption of SGML through mainly educational activities, though some amount of technical activity was also pursued including an update of the CALS Table Model specification and specifications for fragment interchange and entity management.

OASIS. OASIS SOA Reference Model. A reference model in systems, enterprise, and software engineering is an abstract framework for understanding significant relationships among the entities of some environment, and for the development of consistent standards or specifications supporting that environment.

OASIS SOA Reference Model

A reference model is based on a small number of unifying concepts and may be used as a basis for education and explaining standards to a non-specialist. A reference model is not directly tied to any standards, technologies or other concrete implementation details, but it does seek to provide a common semantics that can be used unambiguously across and between different implementations. The Reference Model for SOA is a lexicon that captures the style of architecture known as SOA. Advancing open standards that simplify SOA application development. Aspect-oriented programming. AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while "aspect-oriented software development" refers to a whole engineering discipline.

Aspect-oriented programming

Logging exemplifies a crosscutting concern because a logging strategy necessarily affects every logged part of the system. Logging thereby crosscuts all logged classes and methods. History[edit] AOP has several direct antecedents A1 and A2:[1] reflection and metaobject protocols, subject-oriented programming, Composition Filters and Adaptive Programming.[2] Gregor Kiczales and colleagues at Xerox PARC developed the explicit concept of AOP, and followed this with the AspectJ AOP extension to Java.

AspectJ Development Tools (AJDT) Integrated development environment. An integrated development environment (IDE) or interactive development environment is a software application that provides comprehensive facilities to computer programmers for software development.

Integrated development environment

An IDE normally consists of a source code editor, build automation tools and a debugger. Most modern IDEs offer Intelligent code completion features. Overview[edit] One aim of the IDE is to reduce the configuration necessary to piece together multiple development utilities, instead providing the same set of capabilities as a cohesive unit. Eclipse. Java - eclipse view classes dependency graph plugin. Osx - Open multiple Eclipse workspaces on the Mac. Java (programming language) Duke, the Java mascot Sun Microsystems released the first public implementation as Java 1.0 in 1995.[1] It promised "Write Once, Run Anywhere" (WORA), providing no-cost run-times on popular platforms.

Java (programming language)

Fairly secure and featuring configurable security, it allowed network- and file-access restrictions. Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular. With the advent of Java 2 (released initially as J2SE 1.2 in December 1998 – 1999), new versions had multiple configurations built for different types of platforms. For example, J2EE targeted enterprise applications and the greatly stripped-down version J2ME for mobile applications (Mobile Java). The switch Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

Unlike if-then and if-then-else statements, the switch statement can have a number of possible execution paths.

The switch Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Enum Types), the String class, and a few special classes that wrap certain primitive types: Character, Byte, Short, and Integer (discussed in Numbers and Strings). The following code example, SwitchDemo, declares an int named month whose value represents a month. The code displays the name of the month, based on the value of month, using the switch statement. Concurrency (The Java™ Tutorials > Essential Classes) Computer users take it for granted that their systems can do more than one thing at a time. They assume that they can continue to work in a word processor, while other applications download files, manage the print queue, and stream audio. Even a single application is often expected to do more than one thing at a time.

For example, that streaming audio application must simultaneously read the digital audio off the network, decompress it, manage playback, and update its display. JUnit.

Web development. Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services.

A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. For larger organizations and businesses, web development teams can consist of hundreds of people (web developers). Web application framework. Ruby on Rails. Ruby on Rails. Spring Framework.
