设计一个简单的课程管理系统（CourseManager）。主要功能包括： 课程信息的录入。主要包括：课程号（no）、课程名（name）、学分（grade）等； 课程信息的查询。根据课程号、课程名和学分等查询课程的信息。注意：查询结果可能不唯一。 课程信息的修改。根据课程号查询到指定课程的信息，再用新的内容替换。 课程信息的删除。根据课程号删除指定课程的信息。 设计时，采用层次化设计法，将类分为界面层（ui）、功能层（business）和持久层（persistence）3层，放在不同子包中。整个系统的代码放在exe4_2包中。(Design a simple course management system (CourseManager). Key features include: Entry course information. Including: course number (no), course name (name), credits (grade) and the like Queries course information. Information based curriculum, course name and credit and other inquiries courses. Note: query results may not be unique. Modify course information. Inquiry based curriculum to the specified courses, and then replaced with new content. Remove course information. Remove a specified course of information based curriculum. Design, the use of hierarchical design method, the class is divided into the interface layer (ui), the functional layer (business) and persistence (persistence) 3 layers in different sub-packages. The system code in the exe4_2 package.)

说明：  专门为kettle这款优秀的ETL工具开发的web端管理工具。 kettle作为非常优秀的开源ETL工具得到了非常广泛的使用，一般的使用的都是使用客户端操作管理，但问题是当投入生产环境使用时，动辄上百或几百个job需要管理，这时在使用客户端管理已经很难完成了。我所知道的解决方案有用命令行的调用的，操作麻烦，总之还是很难用啦，还有就是开发web端管理工具，kettle自带了一个web端管理工具，界面极其简陋不说，还很难用，基本无法投入生产环境使用，其他没留意到还有没有较好对众多job进行管理的工具。(A web-side management tool specially developed for kettle, an excellent ETL tool. Kettle as a very excellent open source ETL tool has been widely used, the general use is the use of client operation management, but the problem is that when used in production environment, hundreds or hundreds of jobs need to be managed, when the use of client management has been very difficult to complete. The solution I know has command-line calls, troublesome operation, in short, it is difficult to use, but also the development of web-side management tools, kettle has a web-side management tool, the interface is extremely simple, not to mention, it is also difficult to use, basically can not be put into production environment, other did not notice there is no better. Tools for managing many jobs.)
