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. " Developers may not use the NLM name and/or logo in conjunction with their applications. Supported NLM APIs are listed below, along with information about any additional terms and conditions of use.

Service-oriented architecture. See also the client-server model, a progenitor concept A Service-Oriented Architecture (SOA) is a design pattern in which software/application components provide services to other software/application components via a protocol, typically over a network and in a loosely-coupled way. The principles of service-orientation are 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] By that definition, a service is a discretely invokable operation. However, in the Web Services Definition Language (WSDL), a service is an interface definition that may list several discrete services/operations. And elsewhere, the term service is used for a component that is encapsulated behind an interface. This widespread ambiguity is reflected in what follows.
Definitions[edit] A paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. Service Component Architecture. Service Component Architecture (SCA) is a software technology created by major software vendors including IBM, Oracle and TIBCO. 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: Supporters[edit] In addition to the partners above, the SCA community has a significant set of formal supporters.[3] The Supporters Program remains open for any interested vendor, ISV, customer or user of the SCA technology to contribute to its evolution.
Definition[edit] On March 21, 2007, the OSOA Collaboration released the V1.0 level of specification.[4] The specifications specify that an application designed with SCA should have the following advantages: Further analysis[edit] Advantages: Disadvantages: [edit] 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 (osoa.org) 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. These services are then assembled into solutions called composite applications to address a particular business need. In addition to providing a model to compose services, SCA can be utilized in the creation of service components to be used in composite applications.
Is SCA standardized? While made up of many industry leading vendors, the Open SOA Collaboration is not intended to be a standards body. The list of participating vendors and supporters is always increasing. No, it is not. Yes. No. 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. 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? BEA, IBM, Oracle, and SAP first got together last November to begin work on the common programming model, along with Iona, Sybase, Xcalia SA, and Zend Technologies Ltd.
Others are joining the mix, including Software AG and Red Hat. This group has concentrated its efforts on two projects - service component architecture (SCA) and service data objects (SDO). Consume functions offered by other components through services called references. New? 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. 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. 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. Description[edit] History[edit] The OASIS SOA Reference Model, is a product of the OASIS SOA Reference Model (SOA-RM) Technical Committee (TC).[1] Prior to this initiative, no standard definition of SOA had existed. Current status[edit] Notes[edit] OASIS Open CSA | Advancing open standards that simplify SOA application development. Aspect-oriented programming. Programming paradigm 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.
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. IBM's research team pursued a tool approach over a language design approach and in 2001 proposed Hyper/J and the Concern Manipulation Environment, which have not seen wide use. The examples in this article use AspectJ. The Microsoft Transaction Server is considered to be the first major application of AOP followed by Enterprise JavaBeans.[3][4] Motivation and basic concepts [edit] A version with all those new concerns might look like this: When the advice can run.
Advice. SpringSource.org. 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. 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.
Reducing that setup time can increase developer productivity, in cases where learning to use the IDE is faster than manually integrating all of the individual tools. Tighter integration of all development tasks has the potential to improve overall productivity beyond just helping with setup tasks. History[edit] IDEs initially became possible when developing via a console or terminal.
One of the first IDEs with a plug-in concept was Softbench. Topics[edit] 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.
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). J2SE designated the Standard Edition. In 2006, for marketing purposes, Sun renamed new J2 versions as Java EE, Java ME, and Java SE, respectively. There were five primary goals in the creation of the Java language:[23] Major release versions of Java, along with their release dates: 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.
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. In this case, August is printed to standard output. The body of a switch statement is known as a switch block. You could also display the name of the month with if-then-else statements: int month = 8; if (month == 1) { System.out.println("January"); } else if (month == 2) { System.out.println("February"); } ... // and so on Another point of interest is the break statement. The output from this code is 8. 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.
Even the word processor should always be ready to respond to keyboard and mouse events, no matter how busy it is reformatting text or updating the display. Software that can do such things is known as concurrent software. The Java platform is designed from the ground up to support concurrent programming, with basic concurrency support in the Java programming language and the Java class libraries. JUnit. Copyright © 2007, 2008, 2009, 2010, 2011, 2012 Lars Vogel Unit testing with JUnit This tutorial explains unit testing with JUnit 4.x. It explains the creation of JUnit tests and how to run them in Eclipse or via own code. This tutorial is part of this Kindle book: 1. Introduction to unit testing 1.1. A unit test is a piece of code written by a developer that executes a specific functionality in the code which is tested.
Unit tests ensure that code works as intended. Typically unit tests are created in their own project or their own source folder to avoid that the normal code and the test code is mixed. 1.2. JUnit unit test in version 4.x is a test framework which uses annotations to identify methods that specify a test. The following code shows a JUnit test method which can be created via → → → . @Test public void testMultiply() { MyClass tester = new MyClass(); assertEquals( "10 x 5 must be 50" , 50 , tester.multiply( 10 , 5 )); } 1.3.

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 development as an industry[edit] Since the commercialization of the web, web development has been a growing industry. Typical areas[edit] Basic[edit] Web application framework. History[edit] Around the same time, full integrated server/language development environments first emerged, such as WebBase and new languages specifically for use in the web started to emerge, such as ColdFusion, PHP and Active Server Pages. Types of framework architectures[edit] Most web application frameworks are based on the model–view–controller (MVC) pattern. Model–view–controller (MVC)[edit] Push-based vs. pull-based[edit] Three-tier organization[edit] In three-tier organization, applications are structured around three physical tiers: client, application, and database.[7][8][9][10] The database is normally an RDBMS.
Framework applications[edit] General-purpose website frameworks[edit] For example, Zend Framework. Discussion forums, wikis and weblogs[edit] For example, WikiBase/WikiWikiWeb. Organizational portals[edit] For example, JBoss Portal or eXo Platform.
