The term 'SOAP' refers to a form of web service protocol. Specifically, SOAP stands for Simple Object Access Protocol, and it is a protocol for exchanging structured information in web services using XML. SOAP enables communication between applications over the internet, acting as a messaging framework that allows different systems to communicate with one another regardless of their underlying technologies or languages. It is widely used for web services due to its robustness, standardization, and ability to provide features like security, transaction handling, and remote procedure calls.
The other options do not accurately describe SOAP. It is not a programming language or a type of database technology, nor is it a user authentication framework. SOAP is specifically focused on enabling communication and data exchange between web services, which is crucial in building interoperable applications.
