design assumption

In this case, developers often assume that the EJBs do not need to be secured since they are not "user-accessible" in their application design, but this assumption is dangerously wrong.

在这种情况下，开发人员常常认为EJB组件不需要保护，因为它们在应用程序设计中不是“用户可以访问的”，但这种想法是一个危险的错误。

This design decision is based on the assumption that a typical portal page contains many URLs and requires the navigational state to be serialized multiple times per request.

这个设计决策基于一个假设，即典型的门户页包含很多url，要求按请求对此对导航状态进行序列化。

This is particularly true since many managers operate under the assumption that any project going long enough cannot avoid periodical design and re-implementation from scratch.

尤其有许多经理总是假定任何项目只要存续的时间够长，肯定免不了周期性地完全推倒，再重新设计和实现。
