自己总结的一些思路，欢迎讨论
1. 需求分析，问问题，列出input, output，可以根据input, output设计API /
interface
2. 分析流程，设计use scenario, 可以用(Given, When, Then)关键词描述
eg: 取款流程
Give a person has a bank account with balance 100
When the person withdraw 30
Then the balance will be changed to 70
3. 根据use scenario设计data model
将上面例子中的名词抽取出来作为对象或属性，动作抽取作为方法
class Person{
long personId;
List accounts;
}
class BankAccount{
long accountId
double balance;
}
class AccountService{
boolean withdraw(long personId, long accountId, double amount){}
double deposits(long personId, long accountId, double amount){}
double getBalance(long personId, long accountId)
}
4. 然后考虑高并发情况下，如何提升Scalability. 可以往LoadBalance, Partition/
Shading，cache等方面考虑
