thank you for your answer…ok… what I understood is I will take the input to a webservice and invoke my top level service… but my questions are
kindly name a few systems that can give input to a webservice
before SOA how was the architecture to get the input to my top level service ( in older versions)…
If my partner also has a webMethods integration server , is there any need of getting input to the webservice? because he can invoke my top level service remotely right?
I don’t really know of any modern IT system, framework, language etc that doesn’t support web services, even the mainframe can handle that.
Services aren’t new to SOA and web services != SOA. The goal here is not to tightly couple your architecture/design. Exposing a flow service to be directly invoke by another system can lead to that aka spaghetti architecture. Before SOA became the hot buzz word it was still a bad idea to tightly couple your flow services. After all someone spent a lot of money to bring in webMethods, tightly tying everything together would defeat the purpose.
Why yes they can but see above why that’s a bad idea. Program to an interface not an implementation.
