Quote2Order Project, Senior Systems Developer
Quote2Order, part of a supply-chain initiative to automate order processing, is now handling over $1 billion in orders per year.
The top level design is model / view / controller on top of a mediator pattern of order-dependent services. All services implement a common interface which passes a sales order as a proprietary network packet.
This design was based on considerations of time, current knowledge of J2EE and robust hardware. The high-level design trades off scalability in favor simplicity and quick development time. Most services use stateless session beans because of minimal requirements for scalability and transaction management.
