DAO模式会破坏内聚性/SRP吗? [英] Does the DAO pattern spoils cohesion /SRP?

问题描述

以我们为例:

class AccountDAO {
    create(){..}
    read(){..}
    update(){..}
    delete() {..}
}

有多少职责? 1或4?

How many responsibilities are there? 1 or 4?

推荐答案

不应严格理解SRP.一个对象应该承担的责任很少，而不是一个".

SRP shouldn't be understood in a strict manner. One object should have very few responsibilities, not "one".

在这里AccountDAO仅负责帐户的持久性，因此它只负责一项.

Here AccountDAO is only responsible for Account persistence, so it has only one responsibility.
