web development


SOAP, the Simple Object Access Protocol, is the powerhouse of web services. It's a highly adaptable, object-oriented protocol that exists in over 80 implementations on every popular platform, including .NET, JavaScript, and PHP. It provides a flexible communication layer between applications, regardless of platform and location. As long as they both speak SOAP, a PHP-based web application can ask a C++ database application on another continent to look up the price of a book and have the answer right away.

SOAP was created collaboratively as an open protocol. Early in its development, XML-RPC was spun off, and now enjoys its own popularity as a simpler alternative to SOAP. Both encode messages as XML, and both use HTTP to transport those messages. SOAP, however, can use other transport protocols, offers a number of high-end features, and is developing rapidly.

A SOAP transaction begins with an application making a call to a remote procedure. The SOAP client script then encodes the procedure request as an XML payload and sends it over the transport protocol to a server script. The server parses the request and passes it to a local method, which returns a response. The response is encoded as XML by the server and returned as a response to the client, which parses the response and passes the result to the original function.

A journey of a thousand miles begins with a single step!

Every project is an opportunity to learn, to figure out problems and challenges, to invent, to reinvent and innovate. Without change there is no innovation, creativity, or incentive for improvement. Those who initiate change will have a better opportunity to manage the change that is inevitable...
