Description: 程序说明：
Form1.cs是应用聚类算法DBSCAN (Density-Based Spatical Clustering of Application with Noise)的示例，可以通过两个参数EPS和MinPts调节聚类。
DBSCAN.cs是实现文件，聚类算法的进一步信息请参考“数据挖掘”或者相关书籍
聚类示例数据来自于sxdb.mdb，一个Access数据库。
已知问题及进一步改进建议：
问题：dbscan.cs行64，SortedList不支持重复键，因此若两个数据点距离相同则无法加入集合
解决：采用人为减小一个微小量，使数据点距离不同且不影响聚类结果
上一解决方案的问题：减小double.Epsilon微小量无助于使SortedList认为两点距离以及不同
解决：采用一个指数增长的微小量，连续重试直至SortedList认为距离已经不同
进一步改进建议：可能通过double的强制转型为内存中的byte类型（假设double型转为8个byte）
然后最后一个byte减去0x01可比较漂亮的解决问题，但是……呵呵，C#中我不会这个操作
也可以自己实现一个SortedList，支持重复键，当然，这，好像是微软应该做的工作了 ^_^

Description: 人事,工资,考勤系统,C#实现
1、查看建模图
本文件夹中的Model目录下包含了系统的数据库模型图和系统建模图，分别使用PowerDesigner和Rational Rose打开。
2、数据库安装
本安装说明是以Microsoft Access 2000为例来阐述的，数据库文件为文件夹ManPowerManage/ManPowerManage/bin/debug目录下的ManPowerManage.mdb文件。数据库无须安装设置，直接就可以运行。
3、把员工照片文件夹picture复制到C:盘的根目录。
4、如果用户安装的是Microsoft Visual Studio .Net 2003，那么可以直接打开ManPowerManage文件夹下的工程，查看代码并进行调试。
5、把数据导入Excel要用到Excel.dll,Office.dll,VBIDE.dll 3个dll文件，请按照本章所讲方法，安装Excel并生成这些dll文件。注意，可执行示例程序的同一目录下必须有Excel.dll文件，否则示例程序将不能把数据输出到Excel。请读者自己按照本章所述，获取Excel.dll文件。
6、本程序没有设置登录窗口，读者可以参照前面的例子自行开发。
