真的很抱歉,由于能力有限,上次的数据库方案写的很是不清楚,那个图的排版更是渣到自己都不想看。。。
无奈,这次好像也和上次一样渣?。。。
在这里稍微解释一下,文档中有两张表,第一张叫概念模型,其实就是ER图啦,方框表示实体,连线表示关系,图中的关系大部分都是一对多的关系,所以一头是一根线的,到另一头则是三根分叉。
第二张叫物理模型,其实就是数据库表的结构,方框表示数据表,连线表示表与表之间的外键联系。从引用外键的表指向被引用的表。
这次主要根据第2、3组提出的问题,增加了一些属性字段,同时加了几张表。
现在的方案一共有19张表(真心没想到会那么多,还是没有算上论坛,在线测试等模块的)
嗯,反正先硬着头皮发上来了,然后周五开会的时候我具体跟大家讲下各个表的内容吧,包括仍然存在的一些不清楚的地方。
下一步我的想法是,大家先针对这些表的结构整理下大概会有些什么样子的数据请求需要我们组做接口的,先把接口定下来。前期还是多多交流吧~~
