I have to draw a component diagram that depicts the architecture of my system along with its subsystem decomposition and its dependencies.

My app follows a 3 tier architecture. All the business logic is contained inside the middle layer, while the upper layer just acts as a system boundary: it gets the HTTP parameter, calls a method and returns a simple response.

For this reason, my presentation layer is composed by only one subsystem. Later, during object design or implementation phase, it might be composed of many classes (For example many Java Servlets) but still part of a single subsystem.

For the middle layer i've adopted a different approach: I partitioned the layer "horizontally" so that each partitions covers different areas of the application domain.

Now i need to depict the interfaces and relationships between my subsystem. This is how it would look like:

The question is: is it possible for a single socket to connect to many balls? Also, can i omit the arrows?
