Final answer:
The primary purpose of SOAP is communication between web services.
Step-by-step explanation:
The primary purpose of SOAP (Simple Object Access Protocol) is communication between web services. SOAP is a protocol designed to facilitate the exchange of structured information in web services. It defines a set of rules for formatting and transmitting messages between applications over a network.
SOAP allows for interoperability between different systems by providing a language-agnostic way to communicate. It allows web services to interact with each other, regardless of the programming language or platform they are implemented on.
For example, if a web application needs to retrieve data from a database on another server, it can make a SOAP request to the web service running on that server, which will process the request and return the requested data back to the application.
