问题 单项选择题

以下是关于结构化系统开发方法的描述。 Ⅰ.逻辑设计与物理设计分开进行,即先建立系统的逻辑模型,然后再建立系统的物理模型。 Ⅱ.阶段的依赖性。即前一个阶段工作的结果是后一个阶段工作的基础, Ⅲ.文档资料可以在系统开发完成后统一编写。 Ⅳ.任何信息系统的开发都适合用结构化分析与设计方法。 Ⅴ.该方法采用自顶向下、由粗到精的思想建立企业的信息模型。 上述描述中,错误的有哪个(些)

A.Ⅰ和Ⅲ

B.Ⅲ和Ⅴ

C.Ⅳ和Ⅴ

D.Ⅲ和Ⅳ

答案

参考答案:D

解析: 文档的标准化是结构化系统分析与设计方法的一个基本原则。文档是用户、系统开发人员之间交流手段,文档对信息系统的开发过程有重要的控制作用。文档通常是对某一阶段的工作成果的记录,也是下一阶段:正作的基础和依据。从这个角度上来讲,所采用的技术必须具有一致性、连贯性,每一个阶段都要追求需求和文档定义的严格性、完整性和准确性。所以文档的编写必须在每个阶段及时进行,不能出现事后文档。

Most recently, it's very common in students who need a parent present for job interviews. Naturally, it's easy to blame the students in these situations, but the bigger problem is us. We—as parents—are so eager to shelter our kids that we fail to realize that this in itself is harming them. As the mother of two young sons, I have to remind myself constantly that the biggest responsibility I have as a parent is to help them develop the skills needed to live in, to live without me. So, I'll let them fail.

I'll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow. And failure along with loss, heartbreak, disappointment, etc.—will be part of growth for them. Call me the anti-tiger mom, but leaving them alone is, my way of helping them become equipped to fit in this world as we know it today. From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish.

My children now are becoming little masters of compromise, but they try to negotiate everything now. It's a small price to help them learn a skill they'll use for the rest of their lives, including when I don't accompany them on job interviews.
