The establishment of the internet has become one of the main highlights of the 21st century.

The popularity of the internet has also led to the founding of different web-based business by means of web services. These web services expand the infrastructure of the internet by means of software in providing connections to other software applications. Simply put, it is just like connecting two electronic devices using the internet as a medium. Web services continue to introduce new things in the World Wide Web. The newest addition of this web service nowadays is the introduction of XML.

XML web services are the newest and are considered as the essential building blocks in terms of distributed computing over the internet. XML has become the platform where open standards as well as communication and association among individuals and applications have established an environment. Different applications are constructed using multiple XML web services from different sources that collaborate regardless of where they are or how they are being implemented. This means that these applications are written in a variety of programming languages which run on various platforms, but because of XML, they can use web services in order to exchange data over a network of computers such as the internet. Using XML web service, all the data that are exchanged are formatted and standardized into XML tags.

There are the three particular advantages in using XML web services. First is that XML web services expose functionality to the web users using a standardized protocol which is usually SOAP. Secondly, they tend to describe the interfaces with accurate detail in order to allow users to build client applications to communicate with them which are provided in an XML document called a Web Services Description Language (WSDL) document. Thirdly, XML web services are registered, enabling potential users to find them easily, which is commonly done through the Universal Discovery Description and Integration (UDDI). With the use of the these web services, users will be able to build new as well as more powerful applications using XML as its building blocks.

There is a number of popular software that uses XML. Many of these were created by Microsoft Corporation thru the .NET using XML web services. This allows users to access the internet using any smart device such as tablets, pocket PCs, internet phones, etc. thru a number of products such as SQL Server 2000, Application Center 2000, Commerce Server 2000, Mobile Information Server, Exchange Server 2000, among others.

With the growing popularity of XML web services, it is expected that in the future, many more applications will be supported and use the internet in order to do things that cannot be done at present. It is possible that in the near future web services such as a calendar service can be made available where setting up appointments with other people can be done online. With imagination and the right vision, the possibilities are endless in making life more convenient thru the World Wide Web.

These actually refer to a set of services that can convert the application you developed into a web application that you can post online so that you will be able to share it to the rest of the world. For example, a Java-based application can be designed in such a way that it will be accessible from a Visual Basic program on Windows. What it essentially does is that it standardizes the language used by the different applications on the Internet so that different types of applications will be able to open other applications, making for higher compatibility.

Web services use the following components in order to work:

  • WSDL (Web Services Description Language);
  • SOAP (Simple Object Access Protocol); and
  • UDDI (Universal Description, Discovery, and Integration).

What are the benefits of getting web services tutorials?

Aside from learning about web services, you will also be able to enjoy several benefits by going through these tutorials. These include:

  • Allowing you to share your applications to different users. With web services, you will essentially be allowing different applications to “talk” with each other.

Furthermore, you will be able to make your application more user-friendly, which increases the likelihood of bringing potential customers to check out what you have to offer to them.
  • Reduced costs. With web services, you no longer have to worry about having to develop different applications for different types of users, since you will essentially be building one that will be compatible for everything else.
  • Understanding the functionality of your own codes. These tutorials will allow you to examine the functionality of the existing codes you’re using over the network. That way, you will be able to manipulate it so that other applications will be able to use it. That way, you will have a broader audience reach instead of just being limited to a certain group of users.

These are only some of the benefits that you can get from web services tutorials. If you’re planning on studying up on web services, make sure that the tutorials that you read are from a reliable source. That way, you are guaranteed that what you are studying is actually correct and relevant to what you’re looking for.
