Transaction Processing System Design

[Natalie Kopple]

I do not know it this is the right forum for two of my questions:

1. What general design/architecture would you recommend using to design a transaction processing system with the highest possible throughput?

2. What externally developed components (i.e., database, messaging systems, caching software) should be used for the design?

Thank you.

Natalie,
Yes, this is the correct forum.

1) Avoid stateful session beans like the plague .

2) It depends on your requirements. A "transaction processing system" isn't enough detail. What does it do?
