Web Services Description Language (WSDL) is an XML-based language used to describe web services. It provides a standardized way to define the structure and behavior of a web service, allowing different applications to communicate and interact with each other over a network.

WSDL defines the following components of a web service:

  1. Service: Represents the collection of related operations offered by a web service.
  2. Port: Specifies the network address for accessing the web service.
  3. Binding: Describes the protocol and message format used for communication with the web service.
  4. Operation: Defines the specific actions that can be performed on the web service, along with their input and output parameters.
  5. Message: Represents the data exchanged between the client and the web service, including the message structure and data types.

WSDL allows developers to generate client-side code or stubs based on the provided service description, making it easier to consume web services in various programming languages. It promotes interoperability by providing a standard way to describe web services, enabling seamless integration between different systems.

With WSDL, service providers can expose their functionalities, and service consumers can understand and utilize those functionalities without having prior knowledge of the implementation details. It plays a crucial role in enabling the development of distributed and interoperable systems based on the principles of Service-Oriented Architecture (SOA).
