排球计分(三层架构)

排球比赛计分,现场工作人员

 

1.  估计时间:一周左右。

2.  开发

需求分析:

作为一个排球比赛的现场工作人员,我需要统计每一名

队员的得分及技术统计,以便颁发每场比赛的最有价值球员奖,

以及确定赛会的最佳阵容。

设计文档:

在界面通过队球员信息进行操作,可以同步到数据库中。查询分数和统计。从数据库中获取运动员分数

设计复审:

自己。

代码规范:

c#对设计进行具体操作;

具体设计:

Dal层

public int regist(TeamInfo team)
{
string strcom = "insert into Team(Team,Number,Name) values(@team,@number,@name);";
SqlParameter[] pms = { new SqlParameter("@team",team.Team ), new SqlParameter("@number", team.Number), new SqlParameter("@name", team.Name)};
return SqlHelper.ExecuteNonQuery(strcom, pms);
}
public bool updateScore(ScoreInfo score)
{
string strcom = "update Score set score=@score,reason=@reason where name=@name;";
SqlParameter p = new SqlParameter("@name", score.Name);
SqlParameter p1 = new SqlParameter("@score", score.Score);
SqlParameter p2 = new SqlParameter("@reason", score.Reason);
int i = SqlHelper.ExecuteNonQuery(strcom, p, p1, p2);
return i > 0;
}
public List<ScoreInfo> search(string where)
{
string strcom = "select * from Score " + where;
using (SqlDataReader dr = SqlHelper.ExecuteReader(strcom, null))
{
if (dr.HasRows)
{
List<ScoreInfo> students = new List<ScoreInfo>();
while (dr.Read())
{
ScoreInfo student = new ScoreInfo(dr[0].ToString(),dr[1].GetHashCode(), dr[2].ToString());
students.Add(student);
}
return students;
}
else
{ return null; }
}
}

bll 层

public bool updateStudent(ScoreInfo score)
{
return scoreinfo.updateScore(score);
}
public List<ScoreInfo> search(string where)
{
return scoreinfo.search(where);
}
public bool regist(TeamInfo stu)
{
return scoreinfo.regist(stu) > 0;
}

事后总结:

对于三层架构不能熟练使用。具体功能的实现要多于其他人交流。以上就是这次的总结。
