1. 系统需求分析
1.1 需求概述
DMS数据挖掘项目是一个基于C/S(Client/Server,客户/服务器)架构的系统。
1.2 需求说明
由DMS客户端和DMS服务器端两部分组成:.
●DMS 客户端作为系统的一部分，其主要任务是对数据进行采集、分析和匹配，并将匹配成功的数据发送到DMS服务器端。
●DMS 服务器端用于接收DMS客户端发送来的数据，并将数据保存到数据库中，DMS服务器端对接收的数据提供监控功能。
2. 系统总体设计
2.1 编写目的
DMS数据挖掘项目可以对多种数据类型进行采集，例如:日志数据信息的采集、物流数据信息的采集等，多种数据信息都是基于继承关系。
2.2 总体设计
2.2.1 功能划分
2.2.2 数据库及表
2.2.3 主要业务流程
3. 详细设计与实现
3.1 表设计
用户表
匹配日志表
匹配物流表
DataTableModelFromList类实现了从文件中读取出日志或物流数据，然后将数据以表格的形式显示出来的功能。
java
package com.qst.dms.entity;
import javax.swing.table.AbstractTableModel;
import java.util.ArrayList;
import java.util.List;
public class DataTableModelFromList<T> extends AbstractTableModel {
// 使用List来创建TableModel
private List<String[]> datas = new ArrayList<>();
// 标志位，区分日志和物流：1，日志；0，物流
private int sign;
public DataTableModelFromList(List<T> data, int sign) {
// TODO Auto-generated constructor stub

String[] arr = (String[])obj.getClass().getMethod("toArray").invoke(obj);
datas.add(arr);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
// 获取表格的行数
public int getRowCount() {
return datas.size();
}
// 获取表格的列数
public int getColumnCount() {
