S-R-W-based Trading System

With the development of e-commerce, payment platform plays a much more important role than before in internet applications. The payment license which was issued by central bank, quickly accelerates the growth of payment industry.So I will say something about the transaction system with high concurrent in this essay to learn how to achieve a better implementation on doing such a system.As we all know, most system, transaction system included, is database centered. Any operation in such system will rely on database, which makes huge pressure on database and thus the database became the bottleneck of the system. In this situation, in order to expand the ability of request processing, we have to spend more money, and risk more to achieve the target.The architecture I study here may rescue the system from the risk of the bottleneck. The data processing will be placed to application side. Many processing will be done in ram, which will increase the speed of processing. Also we can add ram to enhance the processing ability convinently. So this architecture can not only faster processing speed but also lower our cost. Meanwhile, I also did many tries on reforming the business logic, architecture, rpc protocol, and cache.
