What is the difference between the top-down and bottom-up approaches in SOAP Web services?

<> Top-down SOAP Web services include creating WSDL document to create a contract between the web service and the client, with a required code as an option. This is also known as the Contract-first approach. The top-down approach is difficult to implement because classes must be written to confirm the contract defined in WSDL. One of the benefits of this method is that both the client and server code can be written in parallel.

<> Bottom-up SOAP web services require the code to be written first and then WSDL is generated. It is also known as the Contract-last approach. Since WSDL is created based on the code, the bottom-up approach is easy to implement and client codes must wait for WSDL from the server side to start working.
