Web services exchange data between web-based applications using open standard applications, XML, and various protocols. They connect applications on different platforms and offer benefits such as ease of understanding and good support. They can use different protocols for data exchange and work easily through firewalls.
Web services are web-based software applications that exchange data with other web-based applications. Open standard applications, Extensible Markup Language (XML), and various other protocols are used for these exchanges. In their original capacities, these services have been used in larger private network interactions. Today, however, they also include Internet interactions.
Integral to web services, XML is a web document description language. XML is used to describe web page content using the application of hidden tags and identifying labels. This method of classifying web data is extremely effective and makes web content quite easy to identify, analyze and trade.
Web services are useful for connecting applications that operate on different network, hardware, software, and database platforms, performing critical functions for many businesses. For example, they can be used to provide seamless interaction between certain business functions and important applications shared with an organization’s customers, partners, and vendors. These services are also useful for combining software and services from different companies to provide a seamlessly integrated service.
Web services offer many benefits, including, but not limited to, ease of understanding. Processes and data are often text-based to ensure they are as simple as possible for developers to understand. With the access XML provides, developers working on a variety of technologies are able to get started using web services.
Developers have relied on other technologies in the past. Unlike some of the technologies used previously, however, web services are considered easy to control. They also have good levels of support on Unix and Windows systems.
Services of this type can rely on many different protocols to exchange data. Such protocols include HyperText Transfer Protocol (HTTP), File Transfer Protocol (FTP), and Simple Mail Transfer Protocol (SMTP). You can also use XMPP (Extensible Messaging and Presence Protocol).
Another advantage of these services, compared to other technologies, concerns firewalls. With web services there is no need to change the filtering system of the firewall. This is because a web service, which uses HTTP, can work relatively easily through the most commonly used firewall security measures.
