Web service implementation 10 2. PHP SOAP critique 10 3. Online test 10   ASSESSMENT - DETAILED REQUIREMENTS The following is an outline of the requirements of the task. You MUST clarify any uncertainties with module lecturers Task 1 You are required to implement a PHP SOAP based Web Service and demonstrate its operation through the implementation of suitable client and server code. The web service must:  provide a function called xquery which takes a single string parameter representing an XQuery statement and returns a string (xml) representing the results of the query.  provide the means to catch, return and report errors as appropriate.  utilise the functionality and features of PheXist to process XQuery statements upon xml stored in an eXist XML database. Your PHP client code should include suitable xquery calls to your web service server to adequately demonstrate the server's functionality. The output reported to the user must be in the form of the returned xml or a suitably formatted error message You are required to produce a document describing:  the design, implementation and operation of your web service.  the integration of your client and server code with all required elements to provide the web service e.g. Xampp, PheXist and the eXist XML database Task 2 You are required to produce a written critique of the SOAP provision/functionality provided by the current version of PHP. Your text must include a demonstration of how SOAP is employed during the exchanges between the web service client and server. This must include text identifying the SOAP content employed during the Client/Server interaction. You MUST present the material in a standard expected of level III studies i.e. must present arguments of critical evaluation demonstrating an understanding of the concepts investigated/evaluated including references. Although the submission is completed electronically on Blackboard, you are required to submit a CD comprising a copy of your report and all associated files ( php, wsdl, XML and XQuery); Task 3 You are required to attempt an online closed-book test on 24/3/2017 in your timetabled lab. session.
