简易汽车零部件管理系统设计与实现(JAVA)
课程设计 纯Java　 代码完全，有数据库
1) 汽车零部件管理系统中存在如下业务实体：整车（编号、名称、型号、类型、排量、重量、外观尺寸、颜色、生产日期、产地等，也可以看成是一个部件），部件（编号、名称、装配时间、重量、外观尺寸、产地、备注等），零件（编号、名称、类型、材料、重量、外观尺寸、颜色、生产日期、产地等），装配信息（部件编号、零部件编号、装配时间、备注等，部件之间可以嵌套，亦即部件也可以由子部件构成）；
2) 支持对以上相关业务实体的新增、删除、属性编辑、查询等操作；
3) 该管理系统中以上所有业务实体的保存与打开等文件操作。(The curriculum design of pure Java code, database

1) there are business entities of auto parts management system: Vehicle (number, name, type, type, displacement, weight, size, color, production date, origin, can also be regarded as a component part,) (number, name, assembly time, weight, size, origin, notes etc. (), part number, name, type, material, weight Volume, size, color, production date, origin, etc.) the assembly information (part number, part number, assembly time and remark, between the parts can be nested, i.e. parts can also be sub components);

2) support add, on the above related business entity attribute editing, delete, query and other operations;

3) save the management system in all business entities and open file operations.)
