Which design pattern should I use?

I am about to start constructing class diagrams for this system:

or

I obviously want to reuse a tried and tested design pattern for such a
system but unfortunately I don't have great experience in designing systems
like this.

Which design pattern(s) would you recommend I use for this system?

Design patterns can't be chosen from such broad brush information.
They are for solving particular problems that come up in coding.

I read a good bit of the thread you indicated.

a) don't write a high-end system with low-end software and hardware. Assume
less than 100 transactions per second and write accordingly. When you have
the customers, you can afford a better system. Be agile. Write what you
need right now.

b) Each of your components will have different needs, and therefore will
need different patterns applied. RTFM. An excellent starting place for a
beginner in DP is "Design Patterns Explained" by Shalloway and Trott.
(Examples are in Java).

c) Mixing the technology like that is going to cost you a fortune to
maintain. Write the whole thing in Java or in C#. Don't swap back and
forth between Java, C++, and PHP.

Good Luck,
