Denial of Service

A denial-of-service attack is one in which a malicious hacker takes over computers on the Internet and causes them to flood a target site with demands for data and other tasks. Denial of service does not involve a computer break-in; it simply keeps the target machine so busy responding to the automated requests that legitimate users cannot get work done.(DoS攻击是一个恶意的黑客接管了因特网上的电脑并且使他们向目标网站涌出数据需求和其他的任务。DoS不涉及到电脑的入侵,它仅仅保持目标机器非常繁忙地响应自动请求从而使合法的用户无法得到工作量。)

创建一个带有输入参数的嵌套调用的存储过程的方法

在学习SQL的时候,发现我们的教材里没有存储过程的描述,实在是太水了!于是到图书馆借了本SQL server的书,希望能找到完成以下的要求的方法。因为对SQL的语法不熟悉,还是没做出来。上网查阅了之后,还是没有找到我想要的结果。最后,跟同学讨论之后,完成了这个问题,在这里,给出这个问题的解决方法,希望在未来能给网友带来帮助。

题目:

创建并执行带有输入参数的嵌套调用的存储过程proc_嵌套_学生成绩,输入学生的姓名,可以查询学生的每门课的成绩。首先创建一个带有输入和输出参数的存储过程proc_STU,查询指定学生姓名的学生编号,输入参数保存在“@Sname”,输出参数保存在“@Sno”中,最后根据Sno在Reports表中查询成绩。

首先,先创建存储过程proc_STU:

 

 

 

这个存储过程是用来嵌套在下面这个“proc_嵌套_学生成绩”存储过程中的。接着,就要创建“proc_嵌套_学生成绩”

 

 

 

 

 

要注意以上的语句的!最后,只要输入语句“EXEC proc_嵌套_学生成绩 @Sname=’某某某’”并执行就行了。

RTM(Requirements Traceability Matrix)需求跟踪矩阵

RTM(Requirements Traceability Matrix需求跟踪矩阵,用比较通俗的话来说,就是为了杜绝需求遗漏的表格。

An RTM identifies precisely what each requirement is. A requirements trace matrix is simply a spreadsheet. Let all the stakeholders agree on
documentation is very important. RTM helps keep the traceability between requirements and their sources.(RTM精确地确定每个需求是什么,需求跟踪矩阵仅仅是一个电子表格。让所有的利益相关者同意文档是非常重要的。RTM帮助保持需求和他们的来源的追踪能力)

Requirements Traceability Matrix is used to check to see if the current project requirements are being met, and to help in the creation of a Request for Proposal(提案申请), various deliverable documents, and project plan tasks. If requirements change, it is important to identify when and why they change.

triple constraint(三角约束)

An important focus of project management is the need to manage the so-called triple constraint.(工程管理的一个重要的焦点是管理所谓的三角约束)

Constraint           Importance

Time                The time constraint refers to the amount of time available to complete the project. A tight time constraint could mean increased costs and reduced scope.(时间约束是指用来完成工程的可用的时间量,一个紧的时间约束意味着花费的增加和范围的减少。)

Cost                The cost constraint refers to the amount of budget available to complete the project. A tight cost constraint could mean increased
time and reduced scope.(费用约束是指用来完成工程的可用的预算,一个紧的费用约束意味着时间的增加和范围的减少。)

Scope               The scope constraint refers to what must to be done to produce the project’s end result. Scope is based on customer’s requirements.
Increased scope means increased time and increased costs.(范围约束是指为了做出工程结果什么必须做,范围是建立在客户的需求的基础上的,增加范围意味着时间的增加和费用的增加。)
