某高校开发了一套基于Web的教务管理系统，实现教务管理人员课程设置、学生选课和成绩查询、教师上传成绩以及特殊情况下教务处对成绩进行修改等功能。系统基于Java EE平台实现，采用表单(Form)实现用户数据的提交并与用户交互。
系统要支持：
7在特定时期内100个用户并发时，主要功能的处理能力至少要达到10个请求/秒，平均数据量8KB/请求；
8用户可以通过不同的移动设备、操作系统和浏览器进行访问。
系统实现时，对成绩更新所用的SQL语句如下：
"UPDATE StudentScore SET score="+intCTientSubmitScore+"WHERE Stuent_ID='"+strStudentID+"';"
设计1个测试用例，以测试该SQL语句是否能防止SQL注入，并说明该语句是否能防止SQL注入，以及如何防止SQL注入。

Teams are required for most engineering projects. Although some small hardware or software products can be developed by individuals, the scale and complexity of modem systems is such, and the demand for short schedules so great, that it is no longer ___71___ for one person to do most engineering jobs. Systems development is a team ___72___, and the effectiveness of the team largely determines the ___73___ of the engineering.
Development teams often behave much like baseball or basketball teams.Even though they may have multiple specialties, all the members work toward ___74___. However, on systems maintenance and enhancement teams, the engineers often work relatively independently, much like wrestling and track teams.A team is ___75__ just a group of people who happen to work together. Teamwork takes practice and it involves special skills. Teams require common processes; they need agreed-upon goals; and they need effective guidance and leadership. The methods for guiding and leading such teams are well known,but they are not obvious.
A.size
B.quality
C.scale
D.complexity
