Web Applications Services Examples

A web application service is defined by the W3C as a software system capable of supporting machine-to-machine (M2M) interaction over an Internet, i. H. A network that was developed. Web services are only Web APIs that can be accessed over a network, such as the Internet, and that run on a remote system that also hosts the requested services.

The W3C web service definition includes many different systems. However, in common usage, the term refers to clients and servers that communicate about particular types of messages that conform to the SOAP standard. It is common in both the field and terminology that there is also a machine-readable description of the operations supported by the server written in the Web Services Description Language (WSDL).

The latter is not a requirement for a SOAP endpoint, but it is a prerequisite for automated client-side code generation in many Java and .NET OAP frameworks (frameworks such as Spring and Apache CFX are important exceptions). Some industry organizations, such as WS-I, require both SOAP and WSDL to define a web service.

A redesign of website design is increasingly leading to the use of web application services. The aim of this article is to highlight some uses. In general, services that provide content for web pages are included in their code. The integration of other sources is possible in different ways:

o from i-Frame (Inline Frame)

o with framesets

o With Ajax

o and using server technologies

Integration of web applications

Inline frame

Integration with Inline Frame i-Frame technology is quite simple and requires no special knowledge. A webmaster (or an editor) just needs to know where to put the content, the expected size, and the URL.

frameset

Framesets should only be used if not otherwise possible. Some Internet applications require frames because they reduce the volume of data. A good example of such an application is an internet chat. Nevertheless, there are AJAX techniques that can be used to avoid the use of framesets.

ajax

AJAX and JavaScript technology is one of the most advanced ways to improve the functionality of web applications. The term AJAX for asynchronous JavaScript and XML was first used in February 2005, although JavaScript has been supporting asynchronous requests since 2004.

AJAX uses the XML HTTP request object (XHR) for remote data calls. It is used in some popular services like Gmail, Mambo, Maps, Windows Live Virtual Earth or Map Quest. Unfortunately, this technology has many versions (like HTML) and so there have been attempts to standardize their functionality, and many have come up with projects that support an object-like look of JavaScript such as Prototypes or ASP.net AJAX.

This technology is subject to a security restriction on iframes or framesets. This is an unavailability of pages (data) that are not on the same web server (or even in the same URL path).

server technologies

The limitation of AJAX can still be suppressed by using server-side techniques. Server programming languages ​​can also read remote Web pages.
ASP example:

In combination with server-side and client-side methods, it is possible to create interactive websites with numerous user-supporting elements.

A server programming interaction has prepared several web application services. We would like to introduce some of our own solutions.

Examples of services for websites:

o Support of a short message service

o a meteorological forecast

o Calendar services

o RSS feeds

RSS feeds:

The RSS service has four different versions so far. These are the versions 0.9, 0.9x, 1.0 and 2.0. Each version has its own specifics, but all are based on XML. The 1.0 version is applied with RDF. The simplest versions for developers are 0.9x and 2.0. These use a lightweight XML code and are the easiest to understand.

Syndication is used in different ways, but always associated with certain types of readers. There are AJAX readers such as Google Reader, PHP and ASP readers or even stand-alone applications.
