True or False: A web service uses open standards like SOAP, WSDL, and XML to integrate applications.

A web service indeed utilizes open standards such as SOAP (Simple Object Access Protocol), WSDL (Web Services Description Language), and XML (eXtensible Markup Language) to facilitate the integration of applications. SOAP is a protocol that allows for the communication between applications over the internet using XML as its message format. WSDL is an XML-based language that is used to describe the functionalities offered by a web service, allowing other applications to understand how to interact with it. Furthermore, XML serves as the medium for transferring data between the web service and the requesting applications.

This combination of standards enables interoperability between different software applications, regardless of the programming languages or platforms they are built on. As a result, the statement is true since it accurately reflects how web services integrate applications by using these established open standards.
