I am not sure when we have existing services what diagram we use to
show integration/interfacing of services. I would also like to show
that client is calling service for what reason. If service is going
to publish information then it sends to subscriber for what reason.
So this sounds to be that we are showing processes on diagram and why
one interfaces to other.
If you have link to article talking about such a case please guide me.
Thanks.
On same lines when we connect two services and apply some message note
to it showing say for database access we shall get Pricing data which
direction should be show the arrow. It it be arrow from client to
database or should we show database to client. So whichever diagram
we decide also specify the arrow directions.
