任务提前加入数据Coursera大数据

这是一个生成全排列的程序,采用最小变化算法,相邻两个序列之间只有两个数的次序不同,每交换两个数,便形成一个新的序列,速度非常快.-This is a whole generation with a procedure using the smallest change algorithm sequence between two adjacent only two of several different order every two exchanged a few, it will lead to a new series, very fast.

最短路径2 是有关数据结构的知识 但是程序稍稍有一个小小的失误-Shortest Path 2 is the data structure of knowledge but the procedures are a little bit errors

所有的数据管理都在类模块中进行,在窗体中不直接对结果集和字段操作 , 操作对象是类 属性和类方法.真正实现了数据管理逻辑和用户接口逻辑的分离-all the data management in the category module, the window of which do not directly result sets and field operations, Operation Object class attribute is referring. truly realize the data management logic and the user interface logic of separation

串行口是计算机一种常用的接口，具有连接线少，通讯简单，得到广泛的使用。常用的串口是 RS-232-C 接口（又称 EIA RS-232-C）它是在 1970 年由美国电子工业协会（EIA）联合贝尔系统、 调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是"数据终端设备（DTE）和数据通讯设备（DCE）之间串行二进制数据交换接口技术标准"该标准规定采用一个 25 个脚的 DB25 连接器，对连接器的每个引脚的信号内容加以规定，还对各种信号的电平加以规定。传输距离在码元畸变小于 4% 的情况下，传输电缆长度应为 50 英尺。

Town是一个100% 纯Java API，它位于JDBC API的顶部。这个API的目的是简化和一个JDBC兼容的关系数据库的交互。通过使用Town,可以执行和管理select/insert/update/delete　SQL语句，而不用真正写一行SQL。Town也可以使用任何JDBC连接字符串和内部连接池。-Town is 100% pure Java API, it is located JDBC API the crown. This API goal is the simplification and a JDBC compatible relational database interactive. Through uses Town, may carry out and manage select/insert/update/delete the SQL sentence, but does not need truly to write line of SQL. Town also may use any JDBC to connect the character string and internal connection pond.
