本论文阐述了软件工程专业教辅支撑平台数据库的设计与实现。在明确管理员、教师和学生三个角色的功能时,采集各个不同角色在教辅支撑平台中所需要的数据并进行分析,建立支撑平台的ER模型。在此基础上,在MySQL中设计了数据库software,其中共有16个表格,在一些表格上建立了索引,并使这些表格尽量满足较高的规范化要求。
为了永久保存对象的状态,运用对象-关系映射(ORM)模式中的Hibernate技术实现对象的持久化,把对象存储到数据库中,将关系模型转换为面向对象模型,封装底层数据库的实现。本系统设计了持久化类和作为JavaBean来包装查询结果中的关系数据的类。此外还为管理员域、教师域和学生域提供了访问数据库的接口。本系统使用的是Java语言,开发工具有eclipse、MyEclipse(在MyEclipse里面包含有Hibernate3.0)、Tomcat。
关键词 ER模型 ORM 持久化

The present paper elaborated the software engineering specialized teaching assistant supports the platform database the design and the realization. When is clear about the manager, the teacher and the student three roles functions, gathers each different role to support the data in the teaching assistant which in the platform needs and to carry on the analysis, establishes supports the platform the ER model. In this foundation, has designed database software in MySQL, its Chinese Communist Party 16 forms, have established the index in some forms, and causes these forms to satisfy the higher standardized request as far as possible .
For the permanent preserved object condition, the utilization object - relations mapping (ORM) in the pattern Hibernate technology realization object is lasting, saves the object to the database in, the relational model will transform into the object-oriented model, will seal the first floor database the realization. This system design lasting kind and packed in the inquiry result as JavaBean the relational data kind. In addition also for the manager territory, the teacher territory and the student territory has provided the visit database connection. This system use is the Java language, the development kit has eclipse, MyEclipse (package includes Hibernate3.0 inside MyEclipse), Tomcat .
