做一个简单的交易平台，用户A上传某商品信息，用户B选择商品后，通过支付宝或者微信将钱支付到平台。用户B收到东西后，确认收货，然后钱会到用户A的余额中。用户A可提现到自己的银行卡。或者平台给他转账到支付宝。如果用户A没有发货，钱会退回用户B的余额，用户B通过提现或者平台转账来把钱取出来。
从订单生成到交易完毕，再到用户A提现，这中间都需要记录哪些数据呢？比如，用户的流水信息之类的。
麻烦解答详细一些，不胜感激。

There are two types of users here, one is an ordinary user and the other is a merchant. They are probably: product table, miscellaneous product table, order table, which can be partitioned by month. User table, merchant table, user log, merchant log
