Hi All,
SCEA Part II assignment does not state any interface type for one of the external systems. It only says, that there is an existing system. Then can i assume that it will expose a web service.
I have 2 points here -
1)If I assume for external system to expose a Web Service, then is it wrong, because i am assuming something that may not exist at the time of actual implementation.
And If assumption for Web Service is OK, then does actual Web Service need to be shown in Class and sequence diagrams, and if answer is yes then how, because i dont know, which business method it will expose as a part of Web Service.?
2)
OR Shall i keep a placeholder for future implementation depending on the type of the interface it will provide. Do SCEA exam try to asses the candidate for assumption? Would i be regretting by not assuming any type for external interface? Again question arises that how should I represent in class/sequence diagrams?
Please suggest.
Thanks
